MultiModel For Nam - Meteoblue

Weather models comparison for Nam

• Every model is assigned one colour that is used in all diagrams. The legend next to the diagram has a list with the model names and the corresponding colours.
• The first diagram shows the predicted temperatures for each model. The yellow background indicates daylight. The dashed line represents the average of all models.
• The second diagram shows precipitation amounts: Blue bars indicate precipitation in mm accumulated over one hour. The bars get darker when more models predict precipitation.
• Weather icons are used to display the predicted weather conditions in the third diagram. The background is light blue for clear sky, light grey for light clouds, and dark grey for strong clouds.

The variables shown are from direct model output and not scaled to the exact altitude and position of the selected place.

Frequently, forecasts are spot on, sometimes less accurate and a few times they are completely wrong. It would be great to know in advance if the forecast is likely to be correct, but how? All weather forecasts are computed by computer models, and sometimes these differ significantly, which indicates uncertainty and difficulty to make an accurate forecast of the weather. In such cases, the weather forecast is likely to change on a daily basis. Our MultiModel diagram shows the weather forecast of multiple models from meteoblue and others, mostly national weather agencies. Generally, the uncertainty of the forecast increases with the differences between models.

What to do if the forecast is uncertain?

1. Develop alternatives for your decisions, which are feasible with every possible weather development.
2. Check forecast updates more frequently.
3. Check the progress of actual weather more frequently.
4. Postpone important activities, if they depend strongly on weather.
