Abstract: Since the earliest days of human existence, people have been intrigued by the ever-changing weather and have attempted to forecast its conditions. However, it wasn't until technological advancements provided sufficient support that precise and satisfactory results could be achieved. Even in ancient Greece, prominent mathematicians and philosophers such as Aristotle made endeavors to write books predicting the weather, but their efforts proved futile. Weather forecasting took a significant leap forward in the 17th century with successful data collection. In the 21st century, we now have the capability to collect and interpret weather forecasting data accurately. There are two primary methods of data collection: surface data collection and upper air data collection. Surface data collection involves gathering various atmospheric parameters like temperature, humidity, air pressure, and wind speed from different locations on the Earth's surface. This information offers valuable insights into current weather conditions and aids meteorologists in predicting future weather patterns. Upper air data collection involves observing cloud formations, heat signatures, and wind patterns at higher altitudes. By analyzing these upper air conditions, meteorologists can gain a deeper understanding of atmospheric dynamics and make more accurate predictions about forthcoming weather events. Several methods and techniques are employed in weather forecasting based on the collected data. Persistence forecasting assumes that the current weather conditions will continue without significant changes over a short period. Climatology forecasting relies on historical weather patterns and averages to predict future weather conditions. Barometers, which measure atmospheric pressure, are also used to provide insights into changing weather patterns. Nowcasting is a technique that utilizes real-time observations, radar data, and satellite imagery to make short-term forecasts about rapidly developing weather phenomena. Weather forecasts have numerous applications that extend beyond common knowledge. One of the most critical aspects is the provision of serious weather alerts, enabling people to take necessary precautions in the face of severe storms, hurricanes, or other hazardous conditions. The aviation industry heavily relies on accurate weather forecasts to ensure safe air traffic and minimize disruptions due to adverse weather conditions. Agriculture also greatly benefits from weather forecasts, as farmers can plan their planting, irrigation, and harvesting activities based on predicted weather patterns. Similarly, fishermen depend on weather forecasts to determine the best times for fishing, ensuring a more efficient catch and securing their livelihood. In significant progress has been made in the field of weather forecasting since ancient times. Technological advancements and improved data collection methods now enable us to collect and interpret weather forecasting data with greater accuracy. The diverse range of methods and techniques used in weather forecasting, along with its applications in serious weather alerts, air traffic management, agriculture, and other sectors, have made it an essential tool in our daily lives and economic activities.
