Oh yeah, he'll just get that rainstorm that knocked out his internet to give him a warning next time.

Done and done.

Extra snow is pretty consistent with warming: http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=1427 The atmosphere holds more moisture at the same relative humidity in a warmer world so precipitation events can end up stronger than usual. Snow is just one form of precipitation.

Well, it's all relative.

    From This report

    "SGR 180620 was 5.25 from the Sun at the time of these observations"

    From This report

    "The times of the flares were 21:28:03.5 and 21:30:26.6 UTC"

    So, if you could see our Sun at those times (+- 5.25), or you could see the moon, you could see it. Other reports indicated that it was clearly reflected off the moon also, which would be expected.

    Check the star chart for that time. If Sagittarius was visible, it's likely the flash was too.

    Your repeated question of where are we looking is kind of redundant. We have a full view of the sky at all times. The location of the observer is key to this though. I have no idea where you are, so we may be standing on opposite sides of the planet looking up. For the galactic center, check the star charts for your location and local time, for visibility of Sagittarius A. From my location, I'll be able to see it on Dec 21, 2012, around 2pm, low to the south. It'll be kinda bright, so unless the sun happens to burn out I won't be seeing much other than blue skies.

Point me to a source that shows the lows in Copenhagen were records...

The record for low temperature in Copenhagen on 17 December was 24F set in 1997. The actual temperature for 17 December 2009 was...23F which was a new record low temperature. You can verify this at wunderground...

Typical northern-hemisphere-centredness.

Better yet, make them live here: http://www.wunderground.com/global/stations/WCYLT.html/

... for what should be settled through scientific debate has become. Jeff Masters gives another example.

Except that superconducting power transmission lines are likely to be buried along with their cooling systems. There are a couple of places on Earth where overhead superconducting power lines might work year round, but there's really not much call for a power grid in Antarctica.

Actually not only is that a good idea, but Antarctica could definitely use some long haul power transmission lines.
While I don't think the usual 'grid' method would be worth while (at least financially) a ring or star where each major end point had at least 2 and possibly 3 legs out, for some basic redundancy.

The weather in Vostok for example, where there is a research compound for sure (It is the only one I personally keep tabs on, but for all I know there is more than one) and such places, and their slightly more remote sensor grids could benefit from such a power supply.

One of the colder days just this week is at -90 F (-68 C) with a -126 F (89 C) wind chill factor.
In the March-April months I've seen as low as -120 F (-84 C) with -160 F (-107 C) wind chills.

I'm not sure what the peak temperatures in the summer months are, but assuming the range isn't too wild, that could simplify the cooling systems needed just by taking advantage of the environment.
Of course the reverse is also true. A wide range of temperatures between highs and lows would most likely complicate the cooling systems to be able to maintain a steady cold environment for the super conducting material.

could a 99% efficient solar cell even provide enough electricity to cool/warm/light my home? Of course, but how large of a setup would one need?

Let's see.

according to http://www.wunderground.com/calculators/solar.html I have no idea what I'm talking about.

How much electricity do I need in my home? http://tonto.eia.doe.gov/ask/electricity_faqs.asp says the 2007 average was 936 kWh per month. I'll say I'm average in that respect with a gas furnace and clothes dryer.

that's 11,232 kWhs per year?

At my location, upstate NY on a line from Buffalo to Albany, at 99% efficiency, I would need one 10'x10' panel to generate 13,938 kWhr/year.

So, there you go, Yes, I would like one 12'x12' 99% efficient solar cell (larger than I need, to cover for growth and storing for a rainy day), and really, the cost is important so I would like it for free.

I got tired of repeating myself on Slashdot without cashing in, so I made a blog full of ads and posted there. Now I can repeat myself multiple times in the same article, but at least I'll be shamelessly self promoting at the same time.

Fixed that for you.

Oh, and that version of the Vostok ice core graph you included is horrendously misleading. If you don't overlay the two graphs on top of each other you can easily be fooled into thinking the data suggests that increased atmospheric CO2 lead to higher temperatures. When you do overlay the charts, it becomes clear that the increase in temperature slightly preceded the increase in CO2 in each cycle, including this one.

Are you just making this stuff up?
NASA's Goddard Institute ranks July 2009 as the 2nd warmest July globally ever (right behind July 1998). http://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=1285&tstamp=
And I don't know what 'scientists' you're talking about, but 97% of climatologists agree that global warming exists, and is being influenced by humans. http://news.mongabay.com/2009/0122-climate.html
I've seen the 'petitions' put out by conservative think tanks asking 'scientists' who disagree with global warming to put their names on a list. Their definition of 'scientist' is anyone with a Bachelor of Science. Sorry...but if you're an econ major, you're opinion on global warming pretty much holds no weight. I'll stick with what the climatologists have to say, since they're the ones who would know.

Here you go

Remember Simcity Tornado? ;)

What's the point of these mobile sites again? Why are they different?

Low bandwidth, for one. This weekend I was at a campground, right on the edge of having no signal at all (had to walk a half mile from our campsite to get out of totally dead space), and wanted to check the weather report to see if a storm would hit us. m.wund.com is much more useful than www.wunderground.com in such a circumstance.

Isn't this what's supposed to be solved by different stylesheets for different viewing devices anyway?

Of course stylesheets help, but often you want to send different content to mobile users.

DFW and "downtown Dallas" still appear to cool down at night at least according to:

I guess their measuring points are cooler than some "built up" places with plenty of hot buildings around.

A hot dusty room would have been very welcome at the East camp of the Vostok station, one of the coldest places on earth. I was working to support research at Lake Vostok. At various times, the outside air at the Vostok Station approached and a few times was colder than Dry Ice (colder than -78.5 C (-109.3 F)).

Life outside during the summer was livable (sometimes as warm as -40 C (-40 F)) when the wind was not too strong. But constant daylight made things dull, IMHO. I made better progress in winter and actually felt better during periods of constant darkness but with wind chill factor approaching -90 C (-130 F) you did not get to go outside much and enjoy the darkness.

One annoying thing was having to code and bunk near some potheads in a tiny room. The room was about the size of a three-person pup tent. It had a very low ceiling and just enough room for 3 people to sleep on the floor plus a small table. The table would have been OK for coding, but it had been taken over by the pot plant tanks. I had to code sitting on the floor where I slept.

BTW: They claimed pot helped them deal with the cold, but they left by the end of summer so I suspect they just liked to smoke. Even 6 months later I could still detect the odor in the room. These guys grew their plants in hydroponics tanks with grow lights. Even after they left I kept the tanks going because the plants added color to an otherwise mono-color room. My best moments where coding in the dark with the glow of grow lamps from the corner.

While the inside room temp was OK, the air tended to get stale. The station is high on the ice shelf 3488 m (11444 ft). Being near the pole, the oxygen level drops so the thin air was equivalent to 5000 m (16400 ft) in more common latitudes. So on top of the thin air, it was odd. There was a slight lack of CO2 (I was told due to the difference in partial pressure) that made breathing slightly irregular (according to the base doctor). The air at the station was very very dry (so the hydroponics tanks were very welcome in that regard).

During the summer I had to code on a "Billy Box" laptop. What a worthless pile of crap that XP development environment was! (Sorry MS fans, I don't mean to troll but it was one of the worst aspects of the job). Things got "better" when the laptop hard drive crashed. I managed to convince my boss to let me switch over to my non-Windoz laptop since the final target (a controller for an experiment) didn't care. Most of my work was backed up, but I still had to "code double-time" to catch up form the time lost.

The food was not great. I'm a vegetarian so veggie food was re-hydrated stuff. The pay was OK (and mostly tax free).

OK maybe it is not the worst coding conditions posted, but I'm guessing mine was one of the oddest (coding in the land way down under), driest (almost no moisture at all), thinnest air (equivalent to 5000m (16400 ft)), and coldest (reaching -80 C (-112 F)) at times with a wind chill of almost -90 C (-130F)) you might find.

Oh, and as for using any relevant amount of nuclear weapons on the surface at once -- say, the amount that would be exchanged between India and Pakistan in a nuclear war -- um, no. That would be a Bad Thing(TM).

Looks like a decent solution to the global warming issue... Also if more people starved and died it would leave more room for other species and kick of more evolution. An extra bonus would be even more evolution, again, thanks to all the resulting mutations.

As Nike would had put it: Just do it!

And the radioactivity is really problematic for some of these tasks. For example, oil shale. That was studied a lot in the 70s, and last I saw, it was deemed infeasible because it'd leave the oil too radioactive to be usable.

Oh, and as for using any relevant amount of nuclear weapons on the surface at once -- say, the amount that would be exchanged between India and Pakistan in a nuclear war -- um, no. That would be a Bad Thing(TM).

I think you can actually SEE the ash cloud on Doppler.... (not from Sarah's yard). Try antimating this map and comparing it to this map.

Looks like the Doppler is picking up the plume.

Bah. I don't know why, but the second link got stripped. (Did it think there was a domain mismatch between wunderground.com and WeatherUnderground? Or does someone elsewhere just not like sites named for 60s domestic terror groups?]

You can calculate how much solar energy you get per year by using solar radiation data collected by the weather community. http://www.wunderground.com/calculators/solar.html . You can then use this information to do a calculation on what solar panels will do for your particular location.

http://www.wunderground.com/ uses a subscription-or-advertising model where you can have an add-free experience, if you pay a nominal yearly subscription ($5 USD).

When printing articles or copying text from an article, in an encyclopedia, you really need to have add-less pages.

1 and 2 are a given, right? They may not be the rule on the internet as a whole, but certainly for any self-respecting site.

4 - do you want to spend your time on wikipedia looking up information or playing some game with the advertisers? I don't see the point to this one.

3 - wtf. Like the anti-pirating inserts in my recent DVD's ?! Or perhaps you could propose an example. I'm just having trouble seeing any advertising as 'for the common good' and especially for whose good by whose measure.... sorry, not meaning a troll here but you asked.

I would add a number 5 - adds must be as irrelevent to the content as possible. In a page describing heart medications, would you want a specific brand name to have a presence? So #2 would be modified to stress the not-insensitive part.

However, I'd most certainly prefer Wikipedia remain independent of add revenue.

Uhhh...no.

The big "gotcha" is the 10mph wind.

Go pull up your local weather station on the Weather Underground, and take a look at what percentage of the time the wind was blowing at above 10mph.

It's not terribly *rare*, but also not terribly *common*. The reason why wind turbines and sailboats both tend to be extremely tall is that the winds become both stronger and more reliable at higher altitudes.

Think about it: Air currents are going to be substantially lower at low altitudes, especially when surrounded by houses, trees, and other obstructions that block the wind.

It's a really cool energy source, particularly for devices that don't need to be constantly (or reliably) powered. However, I have some serious doubts as to whether or not this can be used as a primary power source.

On the other hand, if we can make wind power cheap (cheap turbines, which might not be quite as efficient, but still work, and towers constructed out of locally-available materials), a huge impact will be made.

Like it or not, abundant cheap energy will be the quickest route for the 3rd-world nations to eradicate extreme poverty. If we solve this problem, many other problems will be solved very quickly along with it. If we can't provide a solution, there are alternatives, though none are quite as attractive.......

All the Gustav-related nerdiness you could ever wish for over at the Wunderground. Shame the data's not live RSS streaming feeds or somesuch... unless anyone would like to whip up a 'NOLA catastrophe II: this time it's personal" feed? Where's Spider when you need him?

Because, unlike what many of the Global Warming camp would like you to believe, high SSTs are not the only significant factor in the strength of a hurricane.

Jeff Masters has a great blog entry with details on what they think Gustav will do, and that they expect wind shear to limit its strength despite traveling over the warmest waters in the Atlantic.

It doesn't have as nice an interface, but if you're switching in support of NOAA you may as get it from them directly, at weather.gov. (I generally use Weather Underground, which is pretty good, though last I checked they have a lot of ads if you don't block them)

Well, it's not really a "map of disease"
breakouts. In fact the map part is rather just
a shiny pony?

A list could have done just the same amount
of good. Since for the most part each area has
one pushpin that just sums up the area.
[FWIW, I only looked at US pins.]

I was expecting a cluster map, like you see on...
Wunderground Wundermaps

or on...
http://www.housingmaps.com/

At least if it was a cluster map I could
look at an area and think, "I sure as heck
ain't traveling there for work this week."

I think if public interaction would be
allowed, that would turn up the dial to
a more 'fine' resolution rather than the
grainy "Cryptosporidium in local pools"
that I already know about cause I read
the local paper. Or that the measles
outbreak is almost contained. I can get
that from the 10pm news.

That further detracts from the usefulness
of this website as it stands, because I
doubt someone that reads the news less
than I do, would be more likely to go to
a website and search what new diseases
popped up this week. [All hypochondriacs
aside]

It's a good seed/foundation as long as
they have the financial stamina to keep
it going.

Now even weather forecast websites are considered terrorists ?!? Bush HAS got to be stopped !!! C;-)

I knew the FBI were essentially terrorists, I just didn't know they had such a penchant for bombing public buildings. I thought they pretty much stuck to blowing up private buildings of citizens.

Even further I didn't realize the FBI was so seriously against the weather underground. I mean really, they probably have better data than the weather channel.

Yes. Seattle is in Western Washington. If you drive East from Seattle until you cross over the Cascade Mountains, you find yourself in very different weather: dry and hot in the summer. One time I passed through Moses Lake in August, and the temperature was over 100 degrees F (Seattle was more like 75 or 80 degrees F, IIRC).

Moses Lake is in the dry part of the state, and there is a decent airport there, so that's probably why NASA is testing there. Yakima would also be a good choice.

http://en.wikipedia.org/wiki/Moses_Lake,_Washington

Weather data here:

http://www.wunderground.com/US/WA/Moses_Lake.html

Right now it's 77 degrees F in Moses Lake, while it is 63 F in Seattle. (The whole month has been cold and wet. People are calling it "June-uary".)

As for the famous rain in Seattle, it is indeed exaggerated. But we really do get about nine months out of the year with slate grey overcast; heavy clouds block out the sun. I don't mind; I'm happiest in a dark office writing software. But some people get "Seasonal Affective Disorder" (SAD) from the months of bleak darkness. It sure makes you appreciate the other 3 months, though. And you can always drive over to Eastern Washington for some sun.

It joins these wonderful architectural accomplishments:

I'd love working in the building, myself. I can imagine each time I cross over the big gap between the most offset buildings. Each time I did this, I'd need to go up a level to the walkway and cross over a bunch of unused space which will provide more external surface area, thus making cooling more expensive. I'd just love it. People wasting my time on something inefficient is what I live for.

But why a bar code? Why not a bug? Or a CD ROM? Or a finger pressing an ANY key?

It supports both WiFi (WPA2-PSK, if you want it) and 100BT. There's no IR illuminator, but they claim 2 LUX sensitivity. You can find them on the 'Net for about $400.00.

They should definitely check the weather there before attempting to send anyone.

No. At best your going to have an average of different locations at certain temperatures but that has no real reflection of the situation.climate zones depend on climate falling within a given statistical range or anything, or that changing that range would be a change to a completely different zone. What was I thinking?

First, A feedback can have a forcing effect.

Look, you can argue against definitions all you want. Feedback is, by definition, not forcing.

That is to say that a feedback can raise temperatures which under the Co2 model would generally be a forcing.

No! That is feedback. It occurs in response to a long-lasting stimulus, and only in response to that stimulus. Feedback can be positive or negative. What you described is known as "positive feedback".

Water vapor is a feedback and a forcing though, I though I made that clear.

You made it clear that you're wrong.

But under the Co2 models, they aren't prepared to account for water vapor as a variable which is why you see explanations using it as a constant.

In *NO* model is water vapor a constant.

And no, water doesn't average 10 days in the atmosphere because the saturation points differ.

Wow, do we need to go all the way back to the definition of the word average?

I suggest you quite getting your information from loaded sites designed to convince you regardless of the truth. Real science and at least one of the scientist contributing to it is one of them.

I suggest you get your data from somewhere other than your a**^H^H^Himagination.

Because I'm posting late and anonymously.

2008, 30th of January @ 4:30 UTC - Marseille, France: Submarine cable SEA-ME-WE 4 gets cut.

2008, 30th of January @ 8:00 UTC - Alexandria, Egypt: Submarine cable FLAG Europe-Asia gets cut.

2008, 1st of Febuary "early morning" - 56km from Dubai: Submarine cable FLAG FALCON gets cut.

No news of a disruption in SEA-ME-WE-4 is given until after the failure of FLAG Europe-Asia.

FLAG tells the press that for reasons unknown ships were told to drop anchor 86km off shore of Alexandria, Egypt instead of at the usual distance and this damaged the cable.

No official reason from the agency in charge of monitoring SEA-ME-WE 4 (which is owned by a consortium of companies, not FLAG) is given. However some ISPs told their populace that 'tropical storms' had damaged the cable. No evidence of a tropical storm exists

At a yet unspecified time FLAG FALCON is damaged 56km from Dubai. Only explanation given by FLAG is the 'anchor story' repeated from Alexandria.

Speculation:

Distance from Marseille to Alexandria is approximately 2500km.

Top speed of a US Seawolf class submarine is 46km/h.

If a government is involved in the damaging of these submarine cables, it involved more than one vessel. Two at minimum. One for Marseille, and at least one for Alexandria / Dubai.

Most telephone and internet traffic in the middle east has been greatly reduced in capability. If this were intentional it is most likely either the act of the U.S., U.N., or E.U. all of which currently have some armed forces engaged in conflicts in either Iraq or Afghanistan.

At first glance it appears Iran is suffering the worst, and given the recent political atmosphere surrounding the country this is suspicious.

It is too early to tell exactly what is/has happened. Hopefully events start to become clear on February 12th, 2008 as this is the date FLAG has announced it will have the repairs start on the cable.

Currently I am checking to see how extensive the damage is to communication from the Middle East to the rest of the world. At this time it is highly suspicious that not one, not two, but three submarine cables would near simultaneously be severed at major chokepoints in this part of the world, forcing their traffic to pass through U.S. or U.K. networks before the rest of the world.

I sincerely hope my fears are completely unfounded, but there are an awful lot of coincidences piling up at one time.

(Should have hit preview. :( )

I set up my dad's weather station (a Davis Vantage Pro2. Highly recommend it, as does Make Magazine)) is part of cwop.

If you get a good weather station, the system comes with sunshades for thermometer, and obviously you won't put it under a tree if you want the rain gauge to work. The only real guidelines they give you about placement is where to setup your anemometer if you have one. You want to put it 7 meters above ground level, and ideally 20 meters from any obstructions. If there are obstructions (e.g. trees and houses), you want to put it at least 2 meters above them. Of course these siting preferences are some times impractical. In these cases, you can still upload your anemometer data, but it's flagged as suspect. Basically ground level wind readings are worthless, so the NWS doesn't really care.

Each station is part of a sensor network, and like many sensor nets, some nodes are more precise, more accurate, and more timely than others. By combining the data from all the nodes in the net, outliers can be found and corrected. So you see, it's okay that not every node is perfect, just as long as most of the nodes are pretty good, you can still get good data.

Countering systematic errors actually isn't that much more difficult. You have to realize that no station is in isolation. They're part of a network. Like all sensor networks, some sensors are going to be more accurate and more precise than others. All of this data is put together and outliers can be detected and corrected.

There is a box on the page called "Current Conditions." Scroll to the bottom of that box and click on the link called "Google Map of Personal Weather Stations." Here is an example link:

http://www.wunderground.com/stationmaps/gmap.asp?zip=94608&magic=1&wmo=99999

Each of the station icons, which indicate current conditions, can be clicked on to access much more detailed current conditions and often extensive history as well. I'm lucky that a nearby neighbor has one, and I get accurate data from his station all of the time. It's really the ultimate site for weather geeks.

A few years ago I was managing a hazardous material removal in a high profile public location. All of the work was done late at night to maintain access for the public to the building. Each night the crew had to build a 2 story containment of poly sheeting. Of course the site was near the shore and subject to high winds which could blow down even the best containment. Since there was a personal weather station very close by I was able to monitor the windspeed from the comfort of my home. On two nights the wind got over 20mph, and I shut them down for the night to prevent the containment from being blown down.

Why should the government buy you a station? If they are going to put up stations, they'll just put up their own wherever they want them. Why give you a grant so you can have your own weather station, unless you're some kind of weather guru, in which case you probably already bought your own.

The administration on a government grant program alone would cost more than the station, its installation and maintenance. This is a voluntary program of citizens working to help a portion of the government help other citizens. For practical access, go to Weather Underground. They both promote the NOAA program and publish the values from participating stations.

The Davis Vantage models are great and reasonably priced, compared to a year of Starbucks, say, and there are other usable less expensive types available.
Ambient Weather sells stations and software. I have no financial connection with them, other than buying stuff from them. They helped a weather noob (moi) get a system that works well for me. And, yes, I participate in the uploads.

If you've never seen it, Weather Underground uses Google Maps and overlays all the personal weather stations (PWS)in an area view. They even have a published iGoogle gadget.
