When the temperature is below 0℃, in nascent period of cyclone, it is showed there are fine water vapor conditions anywhere in cyclone. In developing period of cyclone, there are fine water vapor conditions at the fore of cold and warm fronts. After cyclone occlude, there are only fine water vapor conditions at fore warm front and cyclone center.
分析表明，在气旋初生期，气旋各部位的冷层都有较好的水汽条件；在气旋发展旺盛时，冷锋前和暖锋前的冷层水汽条件较好；在气旋锢囚后，只有暖锋前的冷层和气旋中心水汽较多。
In developing period of cyclone, there are fine water vapor conditions at the fore of cold and warm fronts.
在气旋发展旺盛时，冷锋前和暖锋前的冷层水汽条件较好；
Tropical cyclone is a high wind speed whirlpool, developed over the warm oceans.
热带气旋是源于温暖的海洋，风力极大的旋涡。
The retrieval of temperatures from AMSU-A soundings is able to clearly reveal the warm-core structure of the cyclone, surface wind speed and sea-level central pressure in relation to the 250-hPa temperature anomaly and a surface area of strong precipitation.
利用AMSU-A温度反演资料能够清晰地揭示热带气旋的暖心结构、地面风速和中心气压与250hPa温度距平的关系，以及强降水的落区等。
Due to the frontal barocline, its temperature field structure evolved from symmetric warm center to asymmetric half cold and half warm extratropical cyclone. And the winds field also has such asymmetric structure.
由于锋面的斜压作用其温度场结构发生了明显变化，由对称的暖心结构演变为半暖半冷的温带气旋非对称结构，相对应的高度场、流场特征亦表现出非对称结构。
The warm core occurs, the cyclone vorticity increases and the divergence alternates with height in the middle-level at the forming stage of MCC, and the levels of ascending motion are thick.
MCC在低空急流中心前方的风速梯度区中形成并发展；MCC形成阶段，中层出现暖中心并且气旋性涡度增大，辐合辐散运动随高度交替出现，量级相当，上升运动的层次较厚。
After cyclone occlude, there are only fine water vapor conditions at fore warm front and cyclone center.
在气旋锢囚后，只有暖锋前的冷层和气旋中心水汽较多。
The results showed that the development and strengthen of instability stratification in Shenyang area resulted from warm advection of Mongolia cyclone foreside, large positive vorticity region and positive vorticity advection.
结果表明：蒙古气旋前部的暖平流、大范围正涡度区和正涡度平流导致了我国沈阳地区不稳定层结的建立和加强；
When the rain is caused by cold front, cyclone or typhoon, the rainfall forecast skill is higher than warm front or subtropical high.
冷锋、气旋和台风影响下的降水预报准确率明显高于暖锋和副高影响下的降水。
Horizontal advection of negative vorticity through the large-scale upper-level trough and the intensified baroclinicity due to the interaction of cold and warm advections before and after the upper-level trough provided a favorable environment for the cyclone to develop and maintain.
大尺度高空槽通过槽前负涡度输送和槽后槽前冷暖平流对斜压不稳定的加强作用为气旋发展和维持提供有利的环境。
The observations page prominently features a map of the UK with a Norwegian-model cyclone over the top of it, complete with cold, warm and occluded fronts.
观察页突出显示了英国的地图，在其顶部具有包括完整冷、暖锢囚锋的挪威式旋风。
There are only fine water vapor conditions at fore warm front and cyclone center.
只有暖锋前的冷层和气旋中心水汽较多。
