People used to assume the development of weather for centuries, but official forecasts appeared just in the 19th century. Forecasts of weather are a result of gathering quantitative data about the present atmospheric state. With the use of scientific conception of atmospheric processes it becomes possible to predict how the atmosphere is going to evolve.
There are different sorts of weather forecasts subject to their period. Short-term forecasts are commonly made for thirty-six hours. Long-dated forecasts can represent a term of three or more months. The exactness of weather forecasts is inversely proportional to their term. Thus, short-term forecasts are the most exact.
