1. T he six components of weather

2. Temperature Temperature is measured with a thermometer and refers to how hot or cold the atmosphere is. Meteorologists report the temperature in two ways: in Celsius (C) and Fahrenheit (F). The United States uses the Fahrenheit system; in other parts of the world, Celsius is used.

3. Atmospheric pressure A high-pressure system usually brings cool temperatures and clear skies. A low-pressure system can bring warmer weather, storms, and rain. Atmospheric pressure changes with altitude.

4. Wind The wind is the movement of air. Wind forms because of differences in temperature and atmospheric pressure between nearby regions.

5. Humidity Humidity refers to the amount of water vapor in the air.

6. Cloudiness Clouds come in a variety of forms. Not all of them produce precipitation. Clouds can affect the amount of sunlight reaching the Earth’s surface.

7. Precipitation Precipitation is water that falls from the clouds towards the ground, especially as rain or snow. Clouds come in a variety of forms.
