Wind Vane-

A wind vane shows the direction of the wind

(North, East, South, or West)

Rain Gauge-

Measures the amount of rainfall

Anemometer-

A dropping barometer usually means we will have some form of precipitation

Front-

A place where two air masses meet

Warm fronts usually bring rain or snow that can last for hours.

Cold fronts usually brings heavy rain or snow-- but passes through QUICKLY

Air masses

An air mass is a large body of air that has about the same temperature, air, pressure and moisture throughout. Air masses are described by two conditions (temperature and humidity).

Humidity

The amount of water vapor in the air

Weather Factors

Weather involve all of the conditions of the atmosphere at a certain time and place. They include: humidity, wind, air pressure, and temperature.
