Dominique's Q&A: Where's the Lightning in a Hurricane?
After the 10pm newscast last night, Dominique asked me why hurricanes don't have lightning? Some do, as we'll get to, but the simple answer is the structure: hurricane winds are on a horizontal trajectory, spiraling inward toward the center and for thunderstorms (and lightning) to develop you need vertical structure. What that means is fast rising air UPWARD into the sky where ice and rain collide in the cold air to create lightning as opposed to a hurricane's horizontal winds.
