Lab 7a Meteorology
Cold, dry air is _______ relatively warm, humid air. Consequently, warmer (lighter) air is forced
to rise above the sloping front overlying colder (denser) air - ANS-denser than

Ascending, unsaturated air _________, cooling at about 10 degrees C per 1000 m of ascent
(5.5 degrees F per 1000 ft) - ANS-expands

The warmer air rising above the front expands and cools as it ascends, and its relative humidity
_________. If saturated, clouds develop and rain or snow may fall from those clouds -
ANS-increases

The relative humidity of saturated (cloudy) air is ___________ - ANS-100%

Clouds (and precipitation) can develop in the ascending branch of a convection current, along a

Comparing figure 7a-1 and figure 7a-2 the cold front with associated precipitation in Oklahoma
in figure 7a-1 advanced with the low-pressure center generally toward the _____. This
movement is evidenced by an increase in sea-level pressure fro Oklahoma City from figure 7a-1
to figure 7a-2 as well as the changing wind direction due to the passing front - ANS-east

Given the advancement described in #7, the advancing front(s) _________ have provided a
lifting mechanism for the air, leading to clouds and precipitation - ANS-would

There is _______ evidence in figure 7a-2 of radar-indicated rainfall ahead of the cold front in
Arkansas, compared to figure 7a-1 for the same location. Your answers to #7 and #8 support
this statement - ANS-more

The air mass on the western flank of the Ontario anticyclone (high pressure) and ahead of the
advancing fronts in the central U.S. in figure 7a-1 experienced seasonable temperatures for that
time of year. In fact, temperatures in Illinois and Indiana (to the north and east of the warm front)
were reported in the _________ degrees F. This air mass was distinct from the air mass to the
south of the warm front, as temperatures to the south (ex Arkansas, Mississippi) were warmer
with higher dew-points - ANS-50s
