大气边界层的研究——从均匀到非均匀

主要从理论、试验角度对大气边界层的研究进行了简要的回顾,尤其对近年来倍受关注的非均匀地表条件下的边界层研究进行了较详细的介绍,并对大气边界层的研究进行了展望。20世纪50年代,Monin和Obukhov提出的Monin-Obukhov相似理论,为现代大气边界层物理学奠定了基础。之后进行的多次大型综合性外场试验,不仅揭示和发现了大气边界层中的许多现象和规律,也验证和发展了Monin-Obukhov相似理论。80年代以后,非均匀地表条件下的大气边界层研究越来越受到关注,一些新的现象被揭示,新的问题被提出,同时也提出了一些新的概念和研究方法。未来10 a,除大气湍流机理等需长期坚持研究外,还应进一步开展非均匀复杂下垫面边界层研究、城市边界层研究和局地边界层气象预报研究。

Atmospheric Boundary Layer(ABL) Research: from homogeneous to heterogeneous

In this paper,the development of ABL research has been reviewed theoretically and experimentally.Especially the recent researches of ABL over heterogeneous surface are introduced in detail.And the prospect of ABL research has been presented.In 1950's,Monin and Obukhov proposed the theory of Monin-Obukhov similarity which is the basis of modern ABL physics.Then,several field experiments had been carried out which had not only shown many phenomena and laws in ABL,but also validated and developed the theory of Monin-Obukhov similarity.After 1980's,more and more attentions have been paid to the ABL over heterogeneous surface.Some new phenomena have been found,new questions have been proposed,and also some new concepts and methods have been proposed.In the next decade,we should further research on ABL over heterogeneous complex surface and Urban Surface and local prediction of ABL.
