Until the 1950s and 1960s, meteorologists made weather forecasts exclusively by hand. After the Second! World War, forecasts were gradually automat through the development! of computer science. Today, supercomputers that simulate the processes taking place! in the atmosphere provide the basis for every forecast, regardless of type and for which user. By applying the laws of physics, supercomputers! calculate where the winds will move and mix cold and warm air! where the atmosphere is more unstable and more favorable for the development of thunderstorms! or where it is more stable.

for Mium-Range Weather Forecasts in Bologna! which has been active since 2021 and is also us by MeteoSwiss. The supercomputer fills an entire! room.

The data provid by weather satellites are essential for the quality of the forecasts calculat by this centre, which cover the entire globe. (Source: ECMWF)
blog series on satellite meteorology
On December 13, 2022, the first satellite of a new generation of European weather satellites was launch into space. The first satellite of the “Meteosat Third Generation”, or MTG for short, the European Organisation for the Exploitation of Meteorological Satellites,
EUMETSAT
, will make an important contribution to improving severe weather warnings, weather forecasts and research into climate change. MeteoSwiss is taking this as an opportunity to dicate a blog series to satellite meteorology.

A source photo that is as accurate as possible
>A description of the initial state of the atmosphere that is as accurate as possible is an essential prerequisite for the numerical prictions of supercomputers to be reliable and to help us. A afternoon tea wide variety of measuring systems from all over the world are us to create this “initial photo”: ground measuring stations provide the air pressure value, radio soundings record the vertical development of the wind direction and spe, sensors mount on aircraft measure germany cell number temperature and humidity at different altitudes and radar devices detect areas of precipitation.
Finally, satellites complete this picture with information covering the entire surface of the Earth. Thanks to their position hundrs or thousands of kilometers above the Earth’s surface, they also provide information about the state of the atmosphere in oceans or desert areas – regions where it is difficult or even impossible to install and operate a dense network of weather stations.
