Weather Forecasting.

Satellites,Maps, Accuracy and DIY

Although the weather is of interest to, and affects, us all, there are specialised scientists who study the weather in great detail. These people are known as meteorologists and they measure and record lots of different aspects of the weather, including temperature, rainfall and wind speed and direction. By doing this and carefully studying the weather, it is possible to forecast how it will change in the future.
In order to do this, information is collected on all the different weather variables from around the world. Weather stations, balloons high in the atmosphere, satellites in space and ships at sea all contribute by collecting the data we require. An example can be seen with this satellite photograph, taken by the Meteosat satellite on 20th March 2000. This shows radiation variations over the Atlantic and Africa, and material of this sort is used all the time in weather forecasts.

Data obtained from all these sources is then fed into computers. The results are plotted on maps which are then used by meteorologists to forecast the weather all over the world.

However, despite all this data and information, the weather is still very difficult to predict. Forecasts are usually fairly accurate, and improving all the time, but they are still not perfect. Weather can change very quickly (for example, if the wind changes direction slightly the rain may pass over and fall somewhere else) which means the forecast can quickly be out of date. Sometimes it can also be difficult to collect all the necessary information at the right time, and incomplete or missing data can cause just as much of a problem. In this sense it is a bit like doing a jigsaw puzzle – it’s not really complete until you have all the pieces!
