Abstract:A bogus vortex with tilt vertical structure is used in the numerical experiments. As shown by results of simulation of 9806 tropical cyclone (TC) after turning west, the simulated TC track resulting from an experiment using a baroclinic bogus vortex is superior to the one using a barotropic bogus vortex. Therefore, when a bogussing scheme for TCs having an analogy to 9806 TC is designed, the tilt vertical structure shall be introduced, which is a new way to improve the bogussing scheme of these TCs.Based on its further studies,it would have a broad prospect for operational practice.
