| Climate and weather take an essential position in our living. Climate defines the environmental conditions, flora, fauna and plenty of other things. For example, equatorial zone is famous for luxuriant vegetation and high humidity. It is understandable that conditions of living there will differ from antarctic area. Unlike climate weather presents atmospheric conditions during a short period. Weather conditions greatly differ according to the season. But even during one season they can be different. Weather changes influence not just the choice of clothes, but our daily activity as well. For instance, in case you are going to spend this or that day in the open air, sudden rain can ruin your plans. That is where forecasts of weather are of great help.
Weather forecasting constitutes scientifically-proved assumption concerning the conditions of weather in the nearest future. It refers to a definite place and a certain period. Since the earliest times people used to predict the development of weather, but official forecasts appeared just in the nineteenth century. Weather forecasts are a result of collecting quantitative data about the state of the atmosphere. With the use of scientific understanding of atmospheric processes it becomes possible to guess how the atmosphere will evolve.
There are various sorts of weather forecasting according to their term. Short-dated forecasts are usually made for 36 hours. Long-term forecasts may represent a period of three or more months. The exactness of weather forecasts is in inverse proportion to their period. This way, short-dated forecasts of weather are the most accurate.
It will be interesting to learn that the first weather forecast was presented on TV in England on November 11, 1936. Nowadays forecasts of weather are available not only on television, but in the Internet as well. You have a possibility to get to know weather forecast for any period of time in any place on the Earth. Forecasts of weather are of great help in planning – everything from clothing to wear tomorrow to when it is the best time to go on vacation. |
