Puzzling Electric Hurricanes

SpaceAdmiral writes "Hurricanes seldom have lightning because they primarily consist of horizontal winds (as opposed to vertical winds). However, three of the biggest storms of 2005 (Rita, Katrina, and Emily) had plenty of lightning and NASA has an interesting write-up about it." Bottom line is "we still have a lot to learn about hurricanes."

    Bottom line: we have a lot to learn about a great deal.

      In other news: Scientists admit that they don't know everything.

      Which wouldn't be noteworthy, except for the numerous other factions that make no such admission, ever.

      Your theology is sophisticated and admirable; unfortunately, it's also not typical of the people who use religion as a blunt instrument to attack science -- and like it or not, there are a lot of those people, and they have significant political power.

      Science could indeed be used as a doctrine of control, but if it were, it would of necessity be warped so far that it would no longer be "science" by any reasonable definition of the word. In fact, there are historical examples: Lysenkoism and Intelligent Design spring immediately to mind, and there are probably others. In order to function, um, scientifically, science requires freedom of both thought and action.

    I don't know much of anything about the equipment they use, but could it just be that we're seeing more lightning because we're lookinging harder and with better equipment?

    Judging by this picture, the moon looks just about the right size to plug the hole in this hurricane.
    Wouldn't that stop it?

  4. But there is Vertical movement... by JasperVal · · Score: 5, Interesting

    Major storms, including severe Thunderstorms and Hurricanes are an oddity in atmospheric conditions specifically because there is vertical movement. Normally the atmosphere is in hydrostatic balance and the vertical speed of an air parcel can be ignored. In a thunderstorm there are severe downdrafts that overpower the pressure gradient force and updrafts stronger than the force of gravity. It's only in severe storms when the atmosphere isn't in hydrostatic balance. Hurricanes couldn't develop without vertical movement; the eye in the center is a result of the surface low "pulling" air from the upper atmosphere down and clearing the clouds; the bands are similar downdrafts with updrafts occurring at the eye wall. There's more to the lack of lightning than no movement.

    "Generally there's not a lot of lightning in the eye-wall region," he says. "So when people see lightning there, they perk up -- they say, okay, something's happening."

    incase the 100mph winds didn't have your attention already..

    sigh.. hurricanes and their egos.
