Resolution:
0.125° x 0.125° (India, South Asia)
参量:
10米风:
地面以上10米高度处风场
描述:
这幅图显示每个模式格点(模式格距约为80公里)地面以上10米处模式计算的平均风矢量。 一般来说,地面以上10米处的实测风要比模式计算的小一些。尽管如此,计算的风速相当 接近实测值。因此,这幅图对水手、冲浪爱好者、滑翔运动爱好者和热气球驾驶员都十分 有用。 (风计算器)

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.
