Z. Liu et al., THE APPLICATION OF ADAPTIVE MESH GENERATED BY ANALYTICAL SOLUTION IN THE TROPICAL CYCLONE TRACK PREDICTION, Progress in Natural Science, 7(6), 1997, pp. 715-722
Based on the former adaptive mesh model for a tropical cyclone track p
rediction, the following improvements were made: (i) an analytical sol
ution was utilized to generate adaptive mesh, so that the consumed CPU
lime was reduced by solving a quasi-linear elliptic equation compared
with that needed by the former scheme; (ii) spherical barotropic prim
itive equations were adopted to replace the local coordinate system; (
iii) the equations under adaptive mesh coordinate were rededuced, whic
h are much simpler than the old ones; (iv) under the condition of cons
erving the resolution near the typhoon center, the number of grid poin
ts were reduced so that CPU time was saved greatly.
