Weather forecasting is a branch of meteorology that involves predicting the future state of the atmosphere based on current weather patterns and data. This field uses a combination of scientific principles, computer modeling, and observations from ground-based and satellite instruments to predict factors such as temperature, precipitation, wind speed, and atmospheric pressure. Weather forecasts are used for a variety of important purposes, including aviation, agriculture, disaster preparedness, and daily planning for individuals and businesses. Forecast accuracy has improved significantly in recent years with advancements in technology and data collection methods.
