Cyclogenesis
qCyclogenesis typically begins along the polar front but may initiate elsewhere, such as in the lee of mountains.
qMinor perturbations
occur along the boundary separating
colder polar easterlies from warmer
westerlies.
qA low pressure area
forms and due to the counterclockwise flow
(N.H.) colder air migrates equatorward
behind a developing cold front.
qWarmer air moves
poleward along a developing warm front
(east of the system).
qClouds and
precipitation occur in association with
converging winds of the low pressure center and
along the developing fronts.
