synoptic scale

Analyzing synoptic scale system, we demonstrate that the mid-latitude cold vortex and subtropical high play major roles in the process of tropical cyclone intensification.

首先通过对大尺度环境场的分析，来阐述这次风暴加强过程中，中高纬冷涡以及副热带高压系统等外部因素的作用。

Synoptic analyses indicate that the stable gross col field and the interaction between a northward moving typhoon ( down into low pressure) and its east lateral Pacific subtropical high were the large scale and mesoscale circulation conditions of the occurred 96 · 8 extraodinary heavy rainfall;

文中的天气分析指出，稳定的大型鞍形场和北移台风（登陆后减弱为低压）与其东侧副热带高压的相互作用是96·8特大暴雨发生的大、中尺度环流条件；

For synoptic scale systems, the SST thermal forcing mainly excites the atmospheric low-frequency oscillation.

对于天气尺度系统, 海温热力场则主要激发出大气低频振荡.

The unstable thermal stratification, cooler at lower level and warmer at upper level, of the sub synoptic scale temperature field facilitated the development of the thermal unstable condition and further strengthened the heavy rainfall;

次天气尺度温度场下暖上冷的热力不稳定层结促进了热力不稳定的发展，促使暴雨增幅；
