摘要:

该文针对干的无粘大气环流方程组的混合问题,讨论其底部边界的混合问题.所采用的分析方法是将该混合问题分解成两部分:一个纯Cauchy问题和一组积分表达式.首先证明了这样的分解与原问题同解,然后用分层方法讨论相应Cauchy问题的适定性,从而得到了原混合问题的适定的充要条件.最后给出了构造适定混合问题解析解的计算方法.

Abstract:

The mixed problem with lower bound for dry inviscid atmospheric circulation equations is discussed. We decompose the problem into two parts: a pure Cauchy problem and a group of integration expressions. We show that such decomposition gives the same solution with the original problem, and discuss wellposedness of the Cauchy problem based on the stratification theory. A necessary and sufficient condition for wellposedness of the original mixed problem is then obtained. A method for obtaining an analytic solution to the wellposed mixed problem is given.

Key words: mixed problem, stratification theory, wellposedness
