Weather Flashcards
Air mass
A large body of air with similar properties through it (temperature and water vapor are most important).
Continental polar
A cold and dry air mass.
Maritime polar
A cold and wet air mass
Maritime tropical
A warm and wet air mass
Continental tropical
A warm and dry air mass
Front
Boundary between two air masses
Warm front
Warm air mass meets and overrides a cold air mass. Warm air moves over cold air. Brings long periods of light drizzle. Brings warmer temperatures.
Cold front
Cold air mass meets and causes a warm air mass to rise. Fast moving. Produces thunderstorms, heavy rain or snow. Brings cooler temperatures
Occluded front
A cold air mass over takes a slower moving warm air mass and forces warm air up. The cold air continues advancing until it meets another cold air mass. Brings cooler temperatures. Usually brings more precipitation.
Stationary front
Cold air mass meets a warm air mass and results in little movement. Drizzles, does not bring heavy precipitation. Little movement or moves back and forth in the same area.
Wind Vane
A wind vane shows the direction the wind is blowing from.
Rain gauge
A rain gauge measures how much rain has fallen
Thermometer
thermometer measure the temperature
Hygrometer
A hygrometer measures the moisture in the air
Barometer
A barometer measures air pressure
