| Abstract: | Based on the dynamic frame of mesoscale model MM5 and Reisner2 explicit cloud scheme,a LN(liquid nitrogen) -seeding scheme was developed and used to simulate the cold fog dissipation for the cold fog event on 26 December 2007 in Beijing area.The seeding effect and the physical mechanism were studied.Furthermore,two sensitive experiments were performed to study the seeding effect under different seeding distances and seeding amounts.The results indicate that when the seeding operation lasts 10 min at seeding... |
