Decay rate of unique global solution for a class of 2D tropical climate model

摘要

This paper is concerned with a time decay for unique global strong solution of a modified version of the tropical climate model originally derived by Frierson-Majda-Pauluis. We prove that ||(u,v,theta)||L2(R2)-> 0 as t ->infinity and obtain the decay rates with ts2||(u,v,theta)(t)||Hs -> 0 as t ->infinity, where s >= 0.
