Weather forecasting is the scientific process of predicting the future state of the atmosphere by collecting meteorological data, analyzing atmospheric conditions, and applying scientific models. It helps in agriculture, aviation, navigation, disaster management, water resource planning, military operations, and daily human activities. Modern weather forecasting combines observational data, advanced technology, and numerical modeling to improve the accuracy and reliability of forecasts. The forecasting procedure begins with the systematic observation of weather elements such as temperature, atmospheric pressure, humidity, wind speed and direction, precipitation, cloud cover, and solar radiation. These observations are collected from a global network of surface weather stations located on land and at sea. Marine observations from ships and buoys provide valuable information about oceanic weather conditions, while automatic weather stations continuously record data without human intervention. The second step is upper-air observation, which provides information about atmospheric conditions at different altitudes. Radiosondes attached to weather balloons measure temperature, pressure, humidity, and wind from the surface to the upper atmosphere. Aircraft equipped with meteorological sensors also contribute valuable observations, especially along commercial flight routes. Remote sensing technologies have revolutionized weather forecasting. Weather satellites continuously monitor cloud formation, cyclone development, storm
