East Coast Cyclone:
Initial Development
The jetstreaks in the polar and subtropical jetstreams move eastward and are on top of the surface coastal front.
The upper-level
divergence associated with
the jetstreaks induced upper-level divergence which then begin the development of a low pressure center on the surface.
Latent and sensible heat releases from the ocean help the development.
The pressure can drop as much as 30mb in 24 hours.
Strong winds and heavy snows lead to blizzard conditions.
East Coast cyclones are
called Noreaster.
