Météo France plans to revolutionize its forecasts with the acquisition of new supercomputers: the goal is to make weather forecasts much more accurate within two years.
To develop their forecast, MeteorologistsMeteorologists Of Weather reportWeather report France uses a climate model. These are programs that simulate the evolution of the environment from the data they collect. To work, these models are based on supercomputers that process weather observation data and calculate the evolution of these parameters.
Météo France has decided to renew its two. Super CalculatorSuper Calculator :” The general public, civil security, air navigation, defense, agriculture, transportation, construction… A supercomputer is beneficial to society, because better forecasting can reduce the impact of extreme weather phenomena and many weather-sensitive systems. Makes it possible to optimize activities. And the climate », announced by Météo France.
The forecasting organization therefore launched a call for tenders in which “ The first deployment in 2025 will be in 2027. with additional computing power in 2029. On that date, Météo France’s supercomputers aim to increase their computing capacity by six times, compared to their current performance. ».
Rain, wind and storms will be better predicted.
Accuracy will be greatly improved: 750 meters for the Arome weather model (compared to 1.3 km currently) and 2.5 km for the Arpège model (compared to 5 km currently). ” For comparison, in the early 1990s, Météo France’s first supercomputer operated on 35 meshes. km”
Concretely, these supercomputers will:
- Orange and Red Alerts with at least six hours notice for further assessment.
- An improvement of about 10 percent in the prediction of rainrain and gusts.
- More reliable forecasting of hurricanes and flood risk in offshore areas.
- To improve the quality of air sector forecasting, and thus better traffic management.
- To better predict climate change, the frequency and intensity of extreme events.
