Weather prediction

Definition

Weather prediction refers to the process of forecasting atmospheric conditions at a specific time and place based on scientific data and models. This practice relies heavily on various data sources, including satellite imagery, radar observations, and historical weather patterns to make informed forecasts. The complexity of the atmosphere and its chaotic nature makes accurate long-term predictions challenging.
