Neerslag NAM Model

Model:

NAM: North American Mesoscale Forecast System "NOAA"

Ververst:
4 times per day, from 0:00, 06:00, 12:00 and 18:00 UTC
Greenwich Mean Time:
12:00 UTC = 13:00 MET
Resolutie:
32km
Parameter:
Neerslag in Europa in mm
Beschrijving:
De kaart "Neerslag" laat 6-uurlijkse model-neerslag in mm zien. Met isolijnen worden contouren van verschillende neerslaghoeveelheden getoond. De modelberekeningen zijn in veel gevallen te gebruiken als verwachte radarbeelden. In frontensituaties is het model behoorlijk nauwkeurig; in buiensituaties wordt het lastiger. Desondanks is het een zeer belangrijk hulpmiddel voor meteorologen, maar ook voor iedereen die neerslagrisico's wil inschatten.
NWP:
Numerical weather prediction uses current weather conditions as input into mathematical models of the atmosphere to predict the weather. Although the first efforts to accomplish this were done in the 1920s, it wasn't until the advent of the computer and computer simulation that it was feasible to do in real-time. Manipulating the huge datasets and performing the complex calculations necessary to do this on a resolution fine enough to make the results useful requires the use of some of the most powerful supercomputers in the world. A number of forecast models, both global and regional in scale, are run to help create forecasts for nations worldwide. Use of model ensemble forecasts helps to define the forecast uncertainty and extend weather forecasting farther into the future than would otherwise be possible.
