Short-term precipitation forecast
How the precipitation forecast is made
Meteum makes the precipitation forecast based on the data received from weather radars and satellites. Information from weather stations is not suitable for this, as it is updated not often enough and is not always accurate. The stations cover the areas unevenly and are located at a great distance from each other.
- Stage 1. Getting data from weather radars and satellites
Weather radars make a 3D image of the atmosphere within a radius of 200-250 km every 10 minutes.
A satellite registers the position of clouds over Europe and part of Asia every 15 minutes.
- Stage 2. Image processing
- The radar and satellite images are uploaded in two convolutional neural networks . Both networks predict precipitation independently:
- They analyze the sequence of images and compare them with the weather forecast made using the Meteum technology.
- They forecast where precipitation areas will move and how their shape will change.
- They make precipitation maps for the next two hours.
- Stage 3. Making the final forecast
The service combines the maps received from the neural networks and displays the final forecast on the weather map layer.
Where to see the precipitation forecast
The forecast is displayed on the weather map layer .
In contrast to other weather maps, the forecast on the precipitation map is made based on the current data received from weather radars and the satellite. The map will tell you whether precipitation is expected near where you live, in which direction a thunder cloud is moving, or when the snowfall is going to end.
The precipitation map covers the territory of Europe, Asia, North and South America.

How often data is updated
The data on the map is updated every 10 minutes (as soon as the service receives information from the radars).
