Weather forecasts can be defined in many ways; One way is to apply science and technology to predict the state of the atmosphere at a future time and place. Although the concept of weather forecasting seems exciting, weather forecasters are taken for granted; people don't realize they have so much to contribute to the economy. ''Is it possible, by any means, to make weather forecasts beyond one or two weeks''. According to Matthew E. Kahn, atmospheric scientists have been proven to report some of the best long-term climate forecasts they have ever had, being able to predict the climate up to six months out. 'advance. a deadline greater than seven days in advance but there is no absolute deadline limit. While short-term forecasts are weather forecasts made for a period of up to 48 hours. Long-term forecasting still has its limitations despite its importance with the use of modern technology and improved techniques to predict the weather. For example, the weather forecast for today or tomorrow will likely be more accurate than the weather forecast two weeks from now. People seem to need to know what's going to happen further than the next few days. Some atmospheric scientists have therefore developed various methods to give general outlooks on what to expect in the longer term. But this outlook differs in several ways from the usual daily forecasts. Weather forecasts for the coming months do not attempt to state with certainty that areas will be hot or cold, humid or diurnal. Instead, outlook is about how the chances of a place being hot or cold will be changed.
