The elements that make up weather are temperature, humidity, precipitation, visibility, wind and atmospheric pressure. Weather describes the behavior of the atmosphere and what effect it is expected to have on the population.
The temperature element is the numerical measure of air in the atmosphere. Temperature is found using a thermometer and can be in Fahrenheit or Celsius. The temperature of the air has an effect on the rate of evaporation in the atmosphere, the amount of humidity and what form precipitation is in. Any state of water that falls from the sky is defined as "precipitation." This can be rain, sleet, snow or hail.
"Humidity" is defined as how much water vapor is in the air. The state in which water is a gas is defined as "water vapor." Humidity is used to predict the chances of precipitation, dew or fog in the atmosphere.
Visibility is the distance in which one can see prominent objects with the naked eye. It is used in weather to describe how far one can see in heavy precipitation.
"Wind" is defined as air that flows in relation to the surface of the Earth. It is measured by direction, speed, characteristics and shifts. Air pressure is caused by the weight of the air pushing down on the surface of the Earth.
