Abstract:
With MM5V3 and its adjoint system, the bogus vortex and the method of 4DVAR are used to generate an optimal initial condition of the typhoon Ma-on, compared with the initialization schemes of traditional Bogussing and Nudging. The results show that the optimal initial field produced by BDA scheme is closer to the observations and the forecast accuracy for both track and intensity is improved effectively.
