East Coast Cyclone:
Prior to Development
• East coast cyclones typically develop after an earlier cyclone originates east of the Rockies and progresses across the continent, which brings cold airs to the East Coast.
• The cold air damming
between the coast and
the Appalachian Mountain leads to the formation of a costal front.
• Prior to the cyclone
development, subtropical
jststream moves northward
to merge with the polar jetstream.
