A weather system refers to the atmospheric conditions in a specific area at a given time, including factors like temperature, humidity, wind, and precipitation. These systems can be large, like a storm front, or small, like a localized rain shower. They are influenced by various elements, including the Earth's rotation, the sun's energy, and geographical features such as mountains and oceans. Weather systems are categorized into different types, such as high-pressure systems and low-pressure systems. High-pressure systems generally bring clear skies and stable weather, while low-pressure systems are often associated with clouds and precipitation. Understanding these systems helps meteorologists predict weather patterns and inform the public.
