暖心结构

在其发展强盛期，MαCS垂直倾斜的上升气流显示出对流风暴云特点，并在对流层中高层具有一定的暖心结构；

During the stage of strong development , the slantwise updraft current of the M α CS exhibited the features of convective storm clouds with a warm core in the mid-upper troposphere .

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。

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 .

热力结构在低层（700~800hPa）间存在弱冷区，而中高层几乎为暖心结构。

In addition , there was weak cold region between 700 ~ 800 hPa , while warm core in the upper-middle troposphere .

热带气旋是具有暖心结构的低压涡旋，其气流的运动是向着中心辐合的。

Tropical cyclone is the low-pressure vortex with a warm core structure , the movement of the airflow is toward the center to convergent .

最为明显的是，发展者低层有明显的暖心结构和深厚的高湿层，使得条件不稳定层深厚；

Especially , the developed depression has a deep high-humidity layer and a clear warm-cored structure in the lower troposphere , the conditional unstable layer is deeper ;

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。

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 .

波动结构分析表明，波动能量具有径向频散，这有可能是飓风暖心结构的一种形成机制。

At the same time , the analysis of wave structure declares that there is radical dispersion of the disturbing energy , which may be one of the formation mechanisms for warm core in hurricane .
