Inverted V Pattern

[GeneratorPower]

Senorpepr can you explain what the "inverted V pattern" is and why it is significant? If you could mark-up a satellite image with the V they are talking about, that would be great.

The only Inverted V I'm aware of is on a sounding where you have a mid level moist layer and the TT/TdTd spread diverges below that. If the sounding is unstable enough, this can lead to high based thunderstorms and with the dry air below, evaporative cooling from the falling rain can lead to intense and highly dangerous dry micro or downbursts from the thunderstorms. Here in AZ these can lead to the Haboobs which are quite common here when the downbursts consolidate.

I think he's talking about with tropical waves.

Not a good idea to have the same term applying to two different things.

Yes, tropical waves and visual appearance with an inverted V pattern. What does this look like?

I was thinking the same thing Steve was thinking, but then I Googled and this is what I found:

Yeah, that's a good paper, even if it is a little old (i.e almost 40 years). For those with low-speed connections, be careful, as that PDF is almost 10MB because instead of being text, the file contains images of each page of the printed paper.
