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:
Windvector in 10 m boven grondniveau
Beschrijving:
In deze kaart is voor elk modelroosterpunt (om de ca. 80 km)de gemodelleerde windvector op 10 m boven de grond (internationale standaard) getekend. De ervaring leert, dat de gemeten windsnelheden in de praktijk meestal wat zwakker zijn dan de berekeningen, maar het scheelt niet veel. Vooral voor zeilers, surfers en vliegeraars is het zeer waardevolle informatie. (wind-calculator)
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.
