Polar Front Theory - Development and
Evolution of a Wave Cyclone, Cont.
(c)- A fully-developed "wave cyclone" is seen 12-24 hours from its inception. It
consists of:
- a warm front moving to the
northeast
- a cold front moving to the
southeast
- region between warm and cold
fronts is the "warm sector"
- the central low pressure (low,
which is deepening with time)
- overrunning of warm air over the
warm front
- cold air surging southward behind
the cold front
- wide-spread precip ahead of the
warm front
- narrow band of precip along the
cold front
- Wind speeds continue to get
stronger as the low deepens - the Available
Potential Energy (APE)is being converted to
Kinetic Energy (KE)
- The production of clouds and
precip also generates energy for the storm as
Latent Heat is released
