Weather variables are the different factors that describe the state of the atmosphere at a given time. Key variables include temperature, which measures how hot or cold the air is, and humidity, which indicates the amount of moisture in the air. Other important variables are wind speed and direction, which affect how weather systems move, and atmospheric pressure, which influences weather patterns. These variables interact with each other to create various weather conditions. For example, high humidity combined with high temperatures can lead to thunderstorms, while low pressure often brings cloudy skies and precipitation. Understanding these variables helps meteorologists predict weather changes and inform the public.
