Weather forecasting

Definition

Weather forecasting is the process of predicting atmospheric conditions at a specific location and time based on the analysis of meteorological data. This involves using various techniques, including numerical models and observational data, to estimate future weather patterns, which are essential for planning daily activities and preparing for severe weather events.
