图9 5月15日04:00实际(A)及植被、风速敏感性试验中casev1(B)、casev2(C)、casev3(D)、casev4(E)、casew1(F)、casew2(G)、casew3(H)、casew4(I)对应的临界摩擦速度的空间分布。栅格表示该时刻沙尘的起沙量在50~3 000 μg·m-2,蓝色框表示此次过程的沙源地
Fig.9 The spatial distribution of actual critical friction velocity (A) and critical friction velocity simulated by casev1 (B), casev2 (C), casev3 (D), casev4 (E), casew1 (F), casew2 (G), casew3 (H), casew4 (I) at 04:00 on May 15. The black grid area indicates sand emission flux is 50-3 000 μg·m-2. The blue box area indicates the sand source of the process
