我国螺旋度的研究及应用
Research and Application on Helicity in China
【摘要】 对自20世纪90年代以来至今国内关于螺旋度理论及应用研究工作进行了较系统地总结,将螺旋度归类为垂直螺旋度、水平螺旋度及完全螺旋度,同时又将垂直螺旋度划分为局地垂直螺旋度和积分垂直螺旋度,详细介绍并给出了每一类螺旋度的计算表达式以及其在天气诊断分析中的应用状况,对螺旋度的应用研究现状进行了简单地分析与讨论,最后展望了未来螺旋度研究与应用的发展方向。
【Abstract】 The domesticstudies of theory and application on the helicity since 1990′s are reviewed substantially and systematically.The helicity is classified as vertical helicity,horizontal helicity and perfect helicity,meanwhile,the vertical helicity is classified as local vertical helicity and integrated vertical helicity.The formulas of vertical,horizontal and perfect helicity are introduced and provided,in the mean time,the status of each kind of helicity application to synoptic diagnosis is induced completely.What is more,the present applied situation of the helicity is discussed and analyzed simply,along with a prospective study in this field at last.
【Key words】 Helicity; Vertical helicity; Horizontal helicity; Perfect helicity; Research and application;
