ATMOS 1010 U OF UTAH EXAM 2 GUIDE
- Where do mid-latitude low pressure systems develop - Answers - o Along the polar
front
does the polar front have a straight structure - Answers - no, it has a wave like structure
what causes a polar front's wave structure - Answers - land masses and ocean
contrasts
large scale mountain ranges
what is an air mass - Answers - extended body of air in the lower troposphere
it has a more/less unifrom temp and moisture
maritime tropic characteristics - Answers - warm and moist
comes from the gulf of mexico
continental polar characteristics - Answers - cold and dry
comes from north/central canada
maritime polar characteristics - Answers - cold and moist
continental tropic characteristics - Answers - warm and dry
types of air masses - Answers - warm, cold, dry, moist
where is maximum wind speed - Answers - upper troposphere
jet stream - Answers - overlying the polar front
experiences upper convergence and upper divergence
weaker winds - Answers - found in the trough, due to weaker coriolis effect taking place
there
also causes upper divergence - Answers - jet max/jet streak
2 ways divergence can be set up - Answers - 2 divergences overlap
the jetmax coincides with the base of the trough
what forms where there is the max amount of upper troposphere divergence - Answers -
surface low pressure
prime formations of low pressure in north america - Answers - Gulf of Alaska
North Pacific Ocean
, East of the front range of the Colorado Rockies
East of the Canadian Rockies
Texas-Louisiana Coast
Coast of the Carolinas
examples of lee cyclogenesis - Answers - low pressure forming areas in the colorado
and canadian rockies
examples of sharp temp contrasts - Answers - low pressure forming areas in texas-
lousiana coast and carolinas
a front that occurs when a cold air mass moves in and replaces a warm air mass
what is a warm front - Answers - the boundary of an advancing mass of warm air, in
particular the leading edge of the warm sector of a low-pressure system.
fronts only occur during - Answers - surface low pressures
How do thunderstorms form? - Answers - warm, humid air rises in an unstable
environment, along the front
weather associated with advancing cold fronts - Answers - active weather
surface drag causes the slope of a frontal boundary to become more gradual - Answers
- true
clouds that form with an advancing warm front - Answers - cirrus, cirrostratus,
altostratus, nimbostratus
stationary front - Answers - a standoff between 2 air masses, no movement
cold vs warm
long periods of rain, often flooding, unsettled weather,
labeled with blue triangles and red semi circles POINTING OPPOSITE DIRECTIONS /
TOWARDS DIRECTION OF MOVING AIR MASSES
occluded front - Answers - a front where a warm air mass is caught between two colder
air masses and brings cool temperatures and large amounts of rain and snow
air masses move same direction
