ATMOS 1010 - EXAM 2 QUESTIONS AND ANSWERS
Mid-Latitude polar front separating low latitude warm air from high latitude cold air -
Answers - This ^
Polar front and overlying upper-tropospheric jet stream - Answers - this ^
Air Mass Types & their region of origin - Answers - - Continental Arctic: Forms in the
arctic
- Maritime Polar: Forms over water in the NE & NW North America/Adjacent oceans
- Continental Polar: Forms over Canada
- Maritime Tropical: Closer to the equator, gulf of ME or Pacific coast ME
Upper-Tropospheric divergence: due to 1) Curvature 2) Presence of jet max; why the
geostrophic wind is non-divergent - Answers - - Upper divergence can occur due to an
enhancement in curvature with hotter or colder air. (Ridge & Trough)
- Jet maxes can cause divergence as well as air enters and exits the jet max
-
Middle latitude low-pressure systems: horizontal dimensions ; comma-shaped cloud
structure - Answers - - These often have a horizontal dimension of 1,000 miles in each
direction
- The cloud distribution of a middle latitude low pressure system, as seen in a satellite
image, is shaped like a comma.
Formation regions of low pressure systems affecting North America - Answers - - Gulf of
Alaska in the North Pacific
- East of the front range of the CO Rockies
- East of the Canadian Rockies in Alberta
- Along the Texas-Louisiana coast
- Along the coast of the Carolinas
Weather fronts, associated with middle latitude low pressure systems, are boundaries
separating colder and warmer air masses, where warmer air is lifted over colder air.
Positioning of warm and cold fronts relative to the center of the low - Answers - - A cold
