Concerning the relationship between
vorticity aloft and the
deepening/filling of surface lows,
all EXCEPT which of the following
statements is correct?
1.
2.
3.
4.
Increasing cyclonic (positive)
relative vorticity induces
downstream surface pressure
falls
Increasing anticyclonic
(negative) relative vorticity
induces downstream surface
pressure rises
A wave will be stable if the
700-hPa wind over it possesses
anticyclonic relative vorticity
A wave will be stable if the
700-hPa wind field over it
possesses cyclonic relative
vorticity
