Numerical Simulation of Near-Surface Wind during a Severe Wind Event in a Complex Terrain by Multisource Data Assimilation and Dynamic Downscaling
Figure 7
The vertical cross section (its position is shown as black solid line in Figure 1(b)) of potential temperature (shaded, unit: K, wind composed by horizontal and vertical velocity (vectors, unit of vertical velocity is 10−2 m s−1) and divergence (contours, unit: 10−5 s−1) at 1200 UTC 20 Oct 2010. (a) WRF; (b) WRF + 3DVAR; (c) the increment between WRF + 3DVAR and WRF (WRF + 3DVAR minus WRF). The white boxes show the downstream regions of the Alataw valley near the three wind towers. The red triangles denote the approximate location of the three wind towers as shown in Figure 1. The black-shaded color denotes the terrain height across the Alataw valley.
