Abstract

The influence of vertical wind shear on the initial vortex spin-up mechanism is investigated using a dry three dimensional nonhydrostatic model. A total of 36 experiments are conducted with different sets of Co, ro and U7.5. The time evolution of maximum vorticity at the level z=750km for U7.5=6m/s shows that vorticity hardly increases until the end of simulation in cases with Co=5k/day. The results of subjective judjements whether the vortex is extended to the ground for experiments with shear are also presented.
