这幅图显示由ANV-模式算出的6到12点和12到18点UTC的最高温度。 
尽管模式算出的2米-温度同实测值常常不一致，但是只要满足下列条件:<br>
1. 有850百帕温度资料；<br>
2. 有天气报；<br>
3. 有经验的预报员，<br>
报好Tmax 2m 是完全可能的。 <br><br>

  <div class="eI2">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.<br>
