Weather phenomena refer to observable atmospheric events that occur due to various factors, including temperature, humidity, and air pressure. Common examples include rain, snow, thunderstorms, and hurricanes. These events can vary in intensity and duration, affecting local climates and ecosystems. Some weather phenomena are caused by specific conditions. For instance, tornadoes form from severe thunderstorms when warm, moist air meets cool, dry air, creating a rotating column of air. Similarly, fog occurs when water vapor condenses into tiny droplets near the ground, reducing visibility. Understanding these phenomena helps us prepare for and respond to changing weather conditions.
