副热带西风带

It is found that in summer, the region between the southern edge of the westerlies and the northern margin in the subtropical anticyclone of the West Pacific is a favorable location for strong deep summer convection and MCS development.

夏季汛期降水主要受东亚夏季风的影响，非台风暴雨的出现与夏季风的进退一致。夏季在东亚西风带南缘和西太平洋副热带高压之间的地区，是夏季最有利于深对流和MCS发展的地区。

During the four years study on the project, we develop a dynamical forecast model that describing the subtropical ridge surface. A new theory on the role of the land-sea thermal difference on the formation of the Subtropical High is advanced. It is concluded that in the summer subtropics over each continent and its adjacent ocean LO, SE, CO, and a double-dominant heating from west to east compose a LOSECOD heating quadruplet. The influence of the Eurasia continent on SH varies according to the seasonal variation. From the ideal numerical simulation it is shown the important role of the Eaiuan continent and the huge topography on the mechanism of formation and mantanence of the SH during the summer. It is verified by the numerical simulation that the extension of the subtropical continent into the tropics greatly enhances the " East Asian monsoon". Through the Rossby energy dissipation theory it is verified that the deep latent convective heating induces the onset of the South China Sea monsoon over the Bay of Bengal. The relationship and mechanism between the precipitaiton over the East Asia and the Subtropicla high is illustrated by the data. It is also found the close phase lock between the east-west shift of the SH and the disturbence of the east wind belt over the tropical troposphere. The interaction between the structure and activity feature of the SH and the Meiyu over the Yangtze-Huaihe river valley is revealed from the data. The numerical simulation verified the impact of the different SH pattern on the path of the typhoon.

Between t+24 and t+36, NARI will cross the ridge axis, and will be subjected to the westerlies to induce a recurvature.

预料百合将会在 24 至 36 小时之后横过副热带高压脊的脊线，随后受西风带的影响转向东北移动。

The results indicated that the effect of deep warm-wet air coming along the behind subtropical high , moving eastward deepening upper trough , shear line and cyclone trough was caused in Zhuanghe , but no strong thunderstorm . The main impact of system is surface cyclone trough ; Low vortex , shear line in 700hPa , 850hPa strengthen the lower convergence , forming a strong momentum of increase and pieces of water vapor ; strong and wide potential pseudo-equivalent temperature frontal zone lied in Zhuanghe area , the establishment of potential instability are indispensable conditions for producing heavy rain .

结果表明：受副热带高压后部深厚的暖湿气流及西风带高空槽、切变线及气旋倒槽等动力系统共同影响，庄河地区出现了大暴雨天气，但没有出现强雷暴，此过程主要影响系统是地面气旋倒槽；700hPa、850hPa低涡、切变线使中低层辐合加强，形成了较强的动力抬升和水汽辐合；庄河地区处于强而宽的假相当位温锋区中，位势不稳定的建立是造成此次强降水的必要条件。

It is forecast that FAXAI will turn to the northeast soon due to the effect of the westerlies.

预料受西风带的影响，法茜将加速转向东北，沿副热带高压脊西北边移动。

The results show that for the global scale characteristics of the vertically integrated vapor flux fields, which is described in terms of the rotational and divergent components of the stationary parts of the vapor field, both GOALS and FGCM--0 can reproduce the subtropical gyres in each hemisphere, the eastward water va- por transport of the mid--latitude westerlies, and the westward vapor transport of equatorial easterlies reasonably, though the precise positions of the gyres simulated by GOALS, and the intensities of the gyre centers in FGCM--0 do not match the observations accurately.

结果表明：(1)对垂直积分的水汽通量场的流函数及其对应的无辐散水汽通量矢量的模拟，三个耦合模式都能够较为合理地再现副热带大洋的涡旋结构、中纬度西风带的东向水汽输送、赤道东风带的西向水汽输送和东亚夏季风水汽输送等行星尺度特征及其季节变化，只是GOALS的涡旋位置、FGCM-0的涡旋中心强度，较之实际略有偏差。
