ATMS 1002 EXAM 1 WITH
COMPLETE SOLUTION
What atmospheric quantity does not always decrease with height? - ANSWER
Temperature
What instrument do we use to measure wind speed? - ANSWER Anemometer
The Coriolis Force is (INSERT ANSWER) at the equator and increases with
latitude - ANSWER Zero
The (INSERT ANSWER) force acts to accelerate air horizontally from rest -
ANSWER Pressure Gradient Force
Where is friction strongest? - ANSWER In a city
Hydrostatic equilibrium is a balance between the vertical pressure gradient
force and - ANSWER Gravity
T or F: Air mass course regions are usually flat with strong surface winds -
ANSWER FALSE
T or F: Thunderstorms always occur along cold fronts - ANSWER FALSE
Which statement about warm fronts is True? - ANSWER Typically produce
longer periods of precipitation than cold fronts
Weather Profiles - ANSWER Know the drawings for snow, ice pellets, freezing
rain/sleet, and rain
Temperature - ANSWER Average speed (or kinetic energy) of molecules in a
substance
, Thermometer - ANSWER Measures Temperature Three scales (C, F, K)
Inversions - ANSWER Occur where temperature increases with height
Troposphere - ANSWER Where we live & where (most) weather occurs!
80% of mass
Temperature usually decreases w/height
Stratosphere - ANSWER 19.9% of mass
Temperature increases w/height
Poorly mixed air
Ozone absorbs UV radiation to break O3 molecules apart (released energy
causes T increase)
Density - ANSWER Mass/Volume
Pressure - ANSWER Force/Area
Standard pressure - ANSWER 1013 mb
500 mb - ANSWER half of sea-level pressure
