Weather prediction

Definition

Weather prediction is the process of forecasting atmospheric conditions at a specific time and location, utilizing data from various sources to determine future weather patterns. It incorporates both short-term forecasts, which focus on immediate changes, and long-term predictions, analyzing trends over days or weeks. This process plays a crucial role in understanding phenomena such as upper atmospheric discharges and wave patterns in the atmosphere.
