| Abstract: | Comprehensive investigation is made of the longitudinal andlatitudinal variations in the large-scale circulation from May to Junein terms of spherical expansion.It is found that the spectrum featuresof the mean large-scale circulation are different at various levels anda spherical wave can be found as the sample for the longitudinal waveat each level. The variations in the features of spherical wave spectrumreflect the at mospheric circulation catastrophe in June, which developsfrom the 100hPa to 500hPa level, and is most significant at the 500hPa level. The characteristics of spherical spectrum are different in wetand dry years and there exists a pronounced difference between thephase of the predominant wave before the beginning of the Mei-yu season and the conversion wave after the period. |
