Weather refers to the state of the atmosphere at a specific time and place, encompassing conditions such as temperature, humidity, precipitation, cloudiness, visibility, and wind. It is a day-to-day phenomenon influenced by the interaction of various atmospheric elements, including air masses, fronts, and pressure systems. Weather differs from climate, which is the average of atmospheric conditions over longer periods. Meteorologists use various tools and technologies, such as weather satellites, radar, and numerical models, to forecast weather conditions and issue warnings for severe weather events like hurricanes, tornadoes, blizzards, and thunderstorms. Understanding and predicting weather is crucial for daily planning, agricultural planning, and disaster preparedness, impacting almost all aspects of human activity.
