Numerical Simulation of Near-Surface Wind during a Severe Wind Event in a Complex Terrain by Multisource Data Assimilation and Dynamic Downscaling

<div>The proportion distribution (unit: %) regarding the difference of absolute error of near-surface wind speed simulation between WRF + 3DVAR + CALMET and WRF + 3DVAR (WRF + 3DVAR + CALMET <i>minus</i> WRF + 3DVAR) for (a) the whole simulation period (0000 UTC 21 Oct to 1200 UTC 23 Oct), (b) the severe wind period (0000 UTC 21 Oct to 0800 UTC 22 Oct), (c) the severe wind decay period (0800 UTC 22 Oct to 2200 UTC 22 Oct), and (d) the weak wind period (2200 UTC 22 Oct to 1200 UTC 23 Oct). The negative values represent smaller simulation biases in WRF + 3DVAR + CALMET than in WRF + 3DVAR. The zero scale is denoted by black dashed line.</div>
