Fronts
cold fronts: move
fast, steep slope, vertical uplift, cumulus type clouds, narrow zone of
intense precipitation, rain, snow, hail, sleet; drama at the frontal
boundary,
warm fronts: move
less quickly, gentler sloping frontal boundary, overunning, stratus clouds
(some cirrus), wide zone of light precipitation, clouds and
precipitation preceed temperature change, rain, snow, sleet, freezing rain.
Sketch a
cross
section of a cold front, and one of a warm front showing:
direction of movement of air masses,
temperature of air masses, shape of front, cloud type and distribution,
and zone of
precipitation. Be able to
describe these
differences and show them on a weather map. Why is freezing rain
unlikely to form at a cold front? Why is hail unlikely to form at
a warm front?
