question
In characterizing an air mass, which of the following statements is NOT true? a) Air masses are usually several kilometers thick. b) Air masses may extend 1,600 km or more across. c) Air masses form only over cold, continental regions. d) Air masses generally have similar temperatures at any given level. e) Air masses are characterized by similar moisture content at any given level.
answer
Air masses form only over cold, continental regions. (Air masses can be greater than 1,600 km across, have similar temperatures and moisture conditions at given levels, and can be several kilometers in thickness. They are not, however, restricted to cold, continental regions.)
question
Which parameters characterize an air mass that develops over an equatorial ocean? a) dry and cold b) humid and warm c) warm and dry d) extremely unstable e) humid and cold
answer
Humid & Warm (an air mass that forms over an equatorial ocean such as the Indian Ocean or the Gulf of Mexico consists of air that is warm and laden with moisture.)
question
The classification of air mass types is based on which parameter? a) moisture content b) distance traveled c) source region d) temperature extremes they cause e) amount of snow or rainfall
answer
Source region (air masses are classified on the basis of the moisture and temperature of the source region where they are from.)
question
Which type of air mass is responsible for depositing large quantities of lake-effect snow during the winter in cities such as Marquette, MI, or Rochester and Buffalo, NY? a) continental polar air mass b) maritime polar air mass c) maritime tropical air mass d) continental tropical air mass
answer
Continental polar air mass (Lake-effect snowfall that arrives in Marquette, Rochester, and Buffalo is produced as cold and dry continental polar air masses move over the warmer Great Lakes, where they receive heat and moisture. This moisture is later deposited as snow as the now humid air mass reaches shore and becomes unstable.)
question
Living in Houston, TX, during the winter, you hear the weather forecaster say a maritime tropical air mass is headed toward the city. What type of weather would you expect to arrive over the next few days? a) colder and wetter than usual b) colder and drier than usual c) warmer and drier than usual d) warmer and wetter than usual e) unseasonably cold
answer
Warmer and wetter than usual (Because the air mass formed over the tropical ocean, the air will tend to be warm. The ocean will also cause an increase in moisture in air mass.)
