WEATHER is atmospheric condition for short- term and certain place which can

vary.

CLIMATE is the long-term of weather patterns for an area.

Meteorologists are scientists who study and predict weather, use several specific

factors, or variables to describe weather.

Elements of weather:

1- Temperature

2- Humidity

3- Precipitation

4- Air pressure

5- Wind speed

Elements of weather Definition

Temperature

Temperature is a measure of the average kinetic energy of

air particles.

Temperature is measured using a thermometer.

Humidity Humidity is the amount of water vapor in the air.

Humidity is measured by a psychrometer.

Air pressure Is the weight / force of the air pushing down on the

surface below.

Air pressure is measured using a barometer.

Wind speed Describes how fast the wind is blowing

Wind is measured by an anemometer.

Precipitation Rain, snow, sleet, or hail that falls from clouds to Earth’s

surface is called precipitation.

Precipitation is often measured using a rain gauge
