Weather

Question 1

Air Mass

Answer 1

a body of air with horizontally uniform temperature, humidity, and pressure.

Question 2

Continental Polar

Answer 2

Continental Polar Air Masses brings cold temperatures and little moisture. Those who live in northern portions of the United States expect cold weather during the winter months.

Question 3

Maritime Polar

Answer 3

Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot

Question 4

Maritime Tropical

Answer 4

Maritime tropical air masses originate over the warm waters of the tropics and Gulf of Mexico, where heat and moisture are transferred to the overlying air from the waters below. The northward movement of tropical air masses transports warm moist air into the United States, increasing the potential for precipitation.

Question 5

Continental Tropical

Answer 5

a tropical continental is a dry air mass formed over land in area close to the equator. An example of a tropical continental is a mass of warm air that forms over northern Mexico.

Question 6

Front

Answer 6

The boundary between two air masses that have different temperatures or humidity

Question 7

Warm Front

Answer 7

the boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system.

Question 8

Cold Front

Answer 8

the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.

Question 9

Stationary Front

Answer 9

A stationary front is a pair of air masses, neither of which is strong enough to replace the other. On a weather map, this is shown by an inter-playing series of blue spikes pointing one direction and red domes pointing the other.

Question 10

Occluded Front

Answer 10

a occluded front is formed when a cold front overtakes a warm front and forces it aloft.

Question 11

Wind vane

Answer 11

A wind vane is a device that measures the direction of the wind. The wind vane is usually combined with the anemometer. Wind direction is the direction from which the wind is blowing.

Question 12

Rain gauge

Answer 12

a device for collecting and measuring the amount of rain that falls.

Question 13

Thermometer

Answer 13

an instrument for measuring and indicating temperature

Question 14

Barometer

Answer 14

an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.

Question 15

Anemometer

Answer 15

An instrument for measuring the speed of the wind, or of any current of gas.
