How to 15 day weather forecastingThe weather forecast (also known as forecasts of the weather, prediction of weather, weather bulletin, meteorological bulletin, newsletter of the time, prediction of the time, weather or weather information) is the application of science and technology to predict the State of the atmosphere during a future period and a locality or region. The history of the weather forecast is old, but the paradigms and the techniques used have changed significantly. The forecasts are to gather as much data as possible on the State of the atmosphere (especially temperature, humidity, wind) and by known atmospheric processes (meteorology) to determine the future weather patterns. However, the chaotic nature of the atmosphere and the incomplete understanding of the processes to less secure forecasts raising the temporary rank of foresight.Citizenship is strongly influenced by the time. For millennia, people have predictions of what would be the time for a day and up for a station. In 650 BC, the Babylonians predicted the time according to patterns of clouds. In 340 BC, Aristóteles described in meteorology of Aristotle (Meteorologica) weather patterns. The Chinese predicted the time at least since 300 BC. The old methods of prediction of the time usually took into account the experience of noted patterns of events. For example, if the dawn was particularly reddish sky, he developed a bad weather. The experience accumulated by generations produced a protopronóstico (weather lore). However, these predictions were not fulfilled and it could not be rigorous statistical testing. With the invention of the Telegraph in 1837, he began the modern era of the weather forecast. Before, it was not possible to carry information about the weather at far distances, and if he was transported to the speed of a steam train, thus the Telegraph gave reports on the conditions of the time of a large area instantly. He thus improved forecasts knowing regional conditions. Imagine a sphere rotating 12,800 km in diameter, with an irregular surface, wrapped by a mixture of 40 km from different gas whose concentration varies spatially and temporarily, and it is heated by a nuclear reactor to 150 million km away. Imagine also that this sphere orbiting nuclear reactor and some regions are heated more during a part of the revolution and other locations are heated during another part of the revolution. And imagine that the mixture of gases generally receives inputs from the surface down, calmly but sometimes becomes violently and highly localized injections continuously. Then, imagine that after the mixture of gases, you are waiting to know the prediction of atmospheric state of a location in the area for one, two or more days in the future. This is essentially the challenge that is day to day by a predictor of the time. "On the difficulty of the forecast weather", Bob Ryan, Bulletin of the American Society of meteorology, 1982 The two personalities that most credited the birth of forecasting as a science were Francis Beaufort (remembered by the Beaufort scale) and his protégé Robert Fitzroy (developer of the Fitzroy barometer). Both were influential in the British Naval and Government circles, and were ridiculed by the press, although his works won academic strength, and were accepted by the Royal Navy, forming the basis of current knowledge of the weather forecast. 15dayweatherforecast.net, 10 day weather, Napoved vremena, Pocasiena10dni.com, http://hikingtiempo.sosblog.com | |
