Dear folks;

I'm writing about the time I was at a public pool and a wind storm hit.
It's the kind which blows straight down and the wind fans out from the
base
of it. I know there's a special term for it but I can't remember it.
These
storms seem to happen in summer and, if I remember right, happen when cold
air suddenly sinks. I sure would appreciate any help. If you want to
write
me privately, is my address. Thanks in advance for
your help.

.... wind shear??
