The results show that the heavy rainfall,which had two main rain belts and significant daily variations,was mainly associated with the active 500 hPa trough,850 hPa shear line,low-level jet and cross-equatorial flows.
结果发现,暴雨的空间分布有着双雨带特征,即南北两条雨带,北面雨带对应着切变线,南面的雨带对应着低空急流;暴雨开始前及暴雨过程中,索马里附近一直维持强盛的越赤道气流,同时在100°~160°E之间也有越赤道气流活动并有西进现象;500hPa西风槽、850hPa切变线是这次过程开始和维持的重要系统;华南上空对流层高层东风的建立是这次过程结束时重要特征;南海北部至广东上空低空急流中心风速的周期性脉动与广东强降水的日变化现象有着很好的对应关系。

The relationships between the large scale circulation characteristics,low-level jet and warm heavy snow in Aletai distract were analyzed.
分析了冬季产生新疆低空急流的大型环流特征及低空急流与阿勒泰暖区大-暴雪的关系。
6) Low level jet
低空急流
1.
The results show that the high potential vorticity,dry air from the upper level of troposphere extended downwards and southwards,which increased the vertical component of the vorticity on the steep iso-entropy plane and promoted the rapid development of the low level cyclone,resulted in a low level jet and the intensive convergence in .
结果表明:这次强沙尘暴天气有明显的干侵入特征,对流层中高层高位势涡度,干空气在西北气流引导下,沿等熵面入侵到边界层;干侵入使对流层低层产生高位涡扰动、锋面气旋环流加强、低空急流形成、边界层辐合增强,从而引发了这次强沙尘暴天气。
2.

分析结果发现,大气运动非平衡强迫、凝结降水的非均匀分布与强烈垂直风切变的耦合作用、“湿度锋”与低空急流的耦合相互作用通过促进低空辐合流的维持,导致了对流云团和暴雨天气的持续。
3.
Based on the improved definition of the low level jets(LLJs) in China,the southwesterly low level strong winds are divided into low level jets that have vertical axes in low level and low level strong winds(LLSWs) that have no wind axes, and the differences of the climatic and synoptic characteristics between them are discussed.
通过从垂直切变角度对中国低空急流的定义,表明西南低层大风现象有两类:有垂直轴的低空急流和无垂直轴的西南低层大风(简称低层大风),并揭示了二者的气候学和天气学特征差异。
补充资料：场流分级法
分子式：
CAS号：
性质：一种只有流动相的分离技术。因为不存在固定相，所以有人认为场流分级法不属于色谱法。但事实上，该法常作为色谱法的一个分支讨论。
