trigger action
triggering effect
Examples
- Water acts as triggering roles in ris , and the roles include several respects as follows : ( 1 ) change the stability of faults
在水库诱发地震中，水体只起到触发作用，其诱发作用体现在几个方面： ( 1 )改变库区断层的稳定性。 - It is found that many severe weathers is related with the action of the gravitational waves of great amplify . so many people think that gravitational wave is the important burst mechanism of the happening of many severe weathers
大气非线性重力波演变和相互作用过程对重大灾害性天气的形成具有重要的触发作用，重力波的演变囿于schr ( - Through analysis of potential vorticity in isobaric surface field , in low - troposphere a positive potential vorticity disturbance exist and form incline disturbance column northward before rainstorm generation , at the same time have also reflected positive potential vorticity disturbance for severe convection weather trigger role in lower - troposphere ; soon positive potential vorticity disturbance in high - troposphere downward , form one vertical disturbance column , now corresponding precipitation develop stage ; in the prosperous stage of rainstorm that maintains isolines of horizontal distribution and still have straight positive potential vorticity disturbance in 600 - 700 hpa isobaric surface field ; when near ground arises negative potential vorticity disturbance , precipitation also weaken
通过对等压面的位涡分析，发现了在暴雨发生前，在对流层低层有正位涡扰动存在并向北形成倾斜的扰动柱，同时也反映了对流层低层正位涡扰动对强对流天气的触发作用；随后高层正位涡向下扰动，形成一个垂直扰动柱，这时对应降水的发展阶段：在暴雨的鼎盛阶段， 600 700hpa上空维持水平分布的等值线，在其上还有正的位涡扰动；当近地面出现负的位涡扰动时，降水随之也减弱。
