Comparative analysis of two typical hail weather in Ningxia under influence of cold vortex over Mongolia;

Analysis of squall lines occurrign in cold vortexes over Northeast China;

The rainstorm usually occurs in the developing stage of northeast cold vortex,not in the declining phase.

Sri Lanka cold eddy and its generation mechanism analysis;

Three-dimension temperature structure of cold eddy-upwelling system off northeastern Taiwan Island in summer and winter;

Based on the historical marine observational data, the basic conditions of the cold eddy in the sea area northeast of Taiwan are analysed, which include the seasonal variations, pattern , structure and other characteristics.

With the continuous improvement in performance of modern aeroengines,the design of air-cooled turbines has become ever more important.

This study introduces the development of an aerodynamic design system and ideology for air-cooled turbines in advanced gas turbines.

Relationships among the Northern Hemisphere Annual Mode,the Northeast Cold Vortex and the summer rainfall in Northeast China;

hrough the investigation into the energetics of a typical case of Northeast cold vortex it has been found that distinct features exist for different periods.

By using the NCEP/NCAR global reanalysis monthly mean data on 500 hPa height from 1958 to 1997,calculations are made for the cumulative annual average intensity index of the Northeast Cold Vortex and the Subtropical High every month.
