| Climate and weather play an essential role in our lives. Climate determines the environment, flora, animal world and lots of other things. For example, equatorial area is known for luxuriant vegetation and high humidity. It is logical that conditions of living there will differ from arctic zone. As distinct from climate weather presents atmospheric conditions during a short period. Conditions of weather significantly differ according to the season. But even during one season they can be different. Changes in weather influence not just our clothing, but our daily activity as well. For instance, if you're going to spend a day out of doors, sudden rain may ruin your plans. That's where weather forecasts are of great help.
Weather forecasting is scientifically-grounded assumption about the weather conditions in future. It refers to a definite place and a certain period of time. For centuries people used to try to predict the development of weather, but official forecasts were created only in the 19th century. Forecasts of weather represent a result of gathering quantitative data about the present atmospheric state. With the use of scientific conception of atmospheric processes it's possible to guess how the weather will change.
There are different sorts of weather forecasts according to their period. Short-dated forecasts are usually made up to 36 hours. The longest forecasts may represent a term of three or more months. The accuracy of weather forecasts is inversely proportional to their period. In such a way, short-dated forecasts are the most accurate.
It'll be interesting to get to know that the first forecast of weather was presented on TV in England on November 11, 1936. Today forecasts of weather are easily available not only on TV, but in the World Wide Web as well. You get a chance to learn forecast of weather for any term in any place on the Earth. Weather forecasts help a lot in planning – everything from clothing to wear the next day to when it's the best time to go on vacation. |
