反气旋性

The re sults show that: the SCS branch of the Kuroshio Current is an important part in the north SCS from Jan. to Dec.; there always exists a large-scale anticyclonic warm vortex on the right of the Kuroshio Current in the whole year.

模拟结果表明：1～12月，黑潮南海分支是南海北部的一支重要海流；黑潮右侧的大尺度反气旋性暖涡全年都存在。

By using the NCEP reanalysis data to run POM, the basical characteristics of the Kuroshio Current, the large-scale anticyclonic warm vortex on the right of it, and the SCS warm current are well simulated. The feature of the great influence of the monsoon on the SCS currents is also shown.

4使用NCEP再分析资料驱动区域海洋模式POM，较好地模拟出了黑潮海流、黑潮右侧的大尺度反气旋性暖涡及南海暖流等海流的基本特征，并反映出南海海流受季风影响较大的特点。

It has been proved that it is due to the strong geostrophy and baroclinity in middle and high latitudes, an anomaly warm anticyclonic flow is generated above a positive SST anomaly at 850 hPa. It is different from the response to the SSTA in tropics.

证明由于中高纬强地转性和斜压性，使得暖SST异常上空850hPa出现了暖性反气旋式高压异常环流，与热带很不相同。

The low-level wind field displayed cyclonic character on the north part of the squall line, whereas on its south part the wind field pattern was anticyclonic, with clear convergence of westerly and southeast inflows in between.

飑线不同位置的水平风场结构有很大不同，在飑线北端，低层是气旋性辐合风场，飑线南端是反气旋性辐合风场，而中部沿强对流窄带的前部是偏西和东南风的风场辐合。

The anomalous heating source over the east coast of Arabian Sea and the Bay of Bengal forced an anomalous anticyclonic circulation over its northwest at the upper level, leading to the strenthening and westward stretching of South Asian High.

阿拉伯海东岸和孟加拉湾地区的异常加热源在其西北侧强迫出的高层异常反气旋性环流，使得南亚高压加强偏西。

When the earth self-rotation parameter fis not equal to zero, the surface wind stress forcing with anticyclonic or cyclonic vorticity may form a corresponding warm or cold gyre in the South China Sea through the Ekman pumping.

当地球自转参数f≠0时，通过埃克曼抽吸作用可在南海分别产生与反气旋性和气旋性海面风应力强迫相对应的暖涡和冷涡。

On one hand, it changes the distribution of meridional wind, thus the geostrophic vortivity develops in the ridge region on the south of the subtropical high at 500 hPa. On the other hand, it causes inhomogeneity of the vertical distribution of diabetic heating, triggering anomalous cyclonic circulation between two ridges and anticyclonic circulation in the ridge region on the south.

这一方面改变了经向风的分布，使500 hPa副高南侧脊线区域地转涡度平流项发展；另一方面引起非绝热加热垂直分布不均匀，在两脊线之间诱生一异常气旋性环流，在南侧脊线区生成异常反气旋环流。

Using the seale separation method, the meso-scale structure of Mcc occ- ured near the Delta Area of the Pearl River is studied. It is shown that there is a meso-scale cyclonic circulation at 1000 hpa level and a meso-scale anticyclon at 200 hpa level associated with the Mcc. The axis of the Meso-scale cyclone center tilts northwestward with height, stretching up to 400 hpa level.

用滤波方法分析了一例发生在珠江口附近地区的Mcc的中尺度结构，结果表明，在对流层下部有中尺度的气旋性涡旋与Mcc相应，涡旋的中心轴线随高度向西北方向倾斜，在地面涡旋的上方200hPa层上，是一中尺度的反气旋性涡旋，中尺度的辐合中心和上升运动中心偏于Mcc的西部，扰动温度场也是非对称的，在对流层上部没有中尺度的暖高压。

On the other hand, when the tropical western Pacific is in a cooling state in spring, convective activities are weakened around the Philippines. In this case, there is an anticyclonic anomaly circulation in the lower troposphere over the South China Sea, and the western Pacific subtropical high shifts westward, thus, the late onset of the SCSM can be caused. Moreover, when the tropical western Pacific is also in a cooling state, convective activities around the Philippines are also weak in summer, since the abrupt northward-shift of the western Pacific subtropical high is not obvious in mid-June and early July and it gradually shifts northward during its northward advance in this case, the East Asian summer monsoon rainband can be maintained in the Yangtze River and the Huaihe River valleys.

相反，当春季热带西太平洋处于冷状态，菲律宾周围对流活动弱，在这种情况下，南海上空对流层下层有反气旋性距平环流，西太平洋副热带高压偏西，从而使得南海夏季风爆发晚；并且，当夏季热带西太平洋也处于冷状态，菲律宾周围对流活动也很弱，在这种情况下，西太平洋副热带高压北进时，在6月中旬或7月初向北突跳并不明显，而是以渐进式向北移动，从而使得东亚季风雨带一直维持在长江流域和淮河流域。

Corresponding to the long-lasting El Nio event, cyclonic anomalous circulation over the eastern North Pacific weakens slowly and anticyclonic anomalous circulation over the western North Pacific strengthens slowly at 850 hPa. Therefore the tropical Pacific westerly anomaly keeps long. The anomalous positive velocity potential over the western South Pacific at 200 hPa, which is related to the strong Australian winter monsoon, helps a long duration of El Nio. Corresponding to the short-lasting El Nio, the anomalous positive velocity potential over the western Pacific at 200 hPa moves eastward quickly and results in the vanishing of El Nio event.

还发现对于持续时间较长的El Nio事件，东北太平洋上850hPa异常气旋性环流减弱和西北太平洋上异常反气旋性环流增强较慢，因此赤道太平洋异常西风维持的时间也较长，而与澳大利亚冬季风加强相关联的南半球西太平洋的速度势正距平的维持，对El Nio的持续也起一定作用；对应持续时间较短的El Nio事件，西太平洋上200hPa速度势正距平的迅速东移，对El Nio的迅速消亡起重要作用。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
