Migrating low pressure system that occurs on the midlatitude. Form where two contrasting air masses meet.
Midlatitude cyclones are ___ in the NH
Counterclockwise
Midlatitude cyclones are ___ in the SH
Clockwise
Jet stream guide midlatitude cyclones ___
West to east
midlatitude cyclone paths are further __ in summer and __ in winter
Northward, southward
Cyclogenesis
Developing stage, begins along polar front where cold and warm air masses converge, creating instability
Open stage
Defined cold and warm fronts, maturing stage, warm air moving northward and cold air moving southward, counterclockwise flow in NH.
Occluded stage
Cold front overtakes warm front, creating and occluded front, surface war front is overrun by cold front; leads to lifting of warm air wedge off the ground, associates with moderate to heavy precipitation. Cyclone continues to wrap up the low pressure.
Dissolving stage
Cut off from energy and moisture sources, cyclone ides when cut off from warm air mass
