天文潮汐在特定地区与寒潮天气发生的关系

RELATION BETWEEN ASTRONOMICAL TIDE AND COLD WAVE WEATHER SYSTEM

摘要: 虽然现代大气物理学认为:“日月引潮力造成的大气潮汐对于大气活动和天气过程没有多大作用,或者是影响微乎其微.”1但是,近几年来,日月引潮力与天气变化关系的研究又掀起一股高潮,有人根据资料分析,发现在某些特定天文条件下,日月引潮力会对天气过程起着不可忽略的影响2.然而,不分地区、不考虑天气系统的笼统统计,结果并不好3.这就说明,日月引潮力要对天气过程起影响,除了要求特定的天文条件外,还要求特定的其他条件(诸如地区等).为此,本文研究了寒潮天气系统.

Abstract: In this paper,the relation among astronomical tide,topography and cold wave weather system is studied.It is shown that the dates when cold wave weather system goes in and comes out some special topographical regions are closely related with astronomical singularity.
