Weather Symbols And Tools

Question 1

Air mass

Answer 1

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

Question 2

Maritime polar air

Answer 2

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. Arctic air masses are extremely cold.

Question 3

Continental polar air

Answer 3

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

Question 4

Continental tropical

Answer 4

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 5

Maritime tropical

Answer 5

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 6

Fronts

Answer 6

A weather (state of atmosphere) front is a boundary separating two masses of air of different densities, and is the principal cause of meteorological phenomena outside the tropics. In surface weather analyses, fronts are depicted using various colored triangles and half-circles, depending on the type of front.

Question 7

Warm fronts

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

Anemometer

Answer 9

Measures wind speed

Question 10

Hygrometer

Answer 10

Measures moisture in the air (humidity)

Question 11

Rain guage

Answer 11

Measures the amount of rain fall

Question 12

Radar

Answer 12

Measures wind and precipitation inside a storm

Question 13

Borometer

Answer 13

Measures air pressure
Low pressure-cloudy/rain
High pressure-sunny/fair weather

Question 14

Wind vane

Answer 14

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 15

Occluded front

Answer 15

As the storm intensifies, the cold front rotates around the storm and catches the warm front. This forms an occluded front, which is the boundary that separates the new cold air mass (to the west) from the older cool air mass already in place north of the warm front.

Question 16

Stationary front

Answer 16

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 17

Climate

Answer 17

the weather conditions prevailing in an area in general or over a long period.

Question 18

Thermometer

Answer 18

an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol that expands and contracts in the tube with heating and cooling.

Question 19

Weather

Answer 19

1.

the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain
