Re: Gaia box
- Good question, Fred.
Fu's data set is essentially the same as Lindzen's and therefore
ignores direction of current, which can be east and west where the
study occurred. What I suggest is the sum of the forcings, with
electrical enhancement or without it, differs from what the forcing
would be without the electrical currents, such that it actually
appears as a "box" you can see. That box exists exactly where cirrus
clouds would exist to be moved electrically.
