Three basic elements of weather are sunlight, air and water Meteorology is the study of weather Meteorologist is a person who studies weather

Weather includes Temperature Air pressure Precipitation Wind direction and speed

Water Cycle: the journey water takes as it circulates from Earth to sky and back again

Water Cycle Vocabulary Accumulation Evaporation transpiration Condensation Precipitation rain, snow, sleet, and hail Accumulation surface runoff and subsurface runoff

Rain Gauges

Temperature scales Metric Standard Boiling point Freezing Point

Measuring Wind Wind is air moving sideways Anemometer measures wind speed Wind speed is measured in miles per hour (mph)

Weather Vanes/ Windsocks A weather vane observes wind direction A windsock shows direction and speed

Air Pressure The air around us has weight that can be measured. We use units called pounds per square inch to identify air pressure.

Barometers High pressure indicates fair weather Low pressure indicates changing, stormy weather

Humidity The measure of moisture in the air. Hygrometers measure humidity.
