气旋性环流 meaning in Chinese
cyclonic circulation
Examples
- Low - level cyclone circulation with high - level anticyclone circulation , is helpful to form low - level convergence and high - level divergence , and make the rising airflow nearby cyclone keep and strengthen so that have offered necessity condition for convection precipitation
低层的气旋性环流和高层的反气旋性环流相配合，有利于形成低层辐合，高层辐散，使得气旋附近的上升气流得以维持和加强，从而为对流性降水提供了必要条件。 - Genetic analysis shows that it may be caused by the difference of the response of each area to winter monsoon ' s abnormal , the kuroshio and our offshore is influenced mostly by heat flux between the sea and atmosphere , but in the other areas , the abnormal current incited by abnormal wind has decisive effect on the change of the sea temperature , at the same time , air pressure also has some impact on the sea temperature
其区域性形成的原因主要可能是因为各海区对冬季风异常的响应方式不同，强冬季风使得黑潮与我国近海海洋过多散热，海温降低；在西北太平洋暖池北部，强冬季风引起西风异常，从而引发异常气旋性环流，海水辐合下沉加热其表层以下海水，同时异常环流使得更多东侧异常暖水向西加热其表层水；在黑潮与亲潮交汇处的升温也主要是由于强冬季风导致的流场异常，海水辐合下沉升温。 - Through analysis of potential vorticity in equity - entropy surface field , a relatively high potential vorticity center in cyclone top in low - troposphere have discovered , and make cyclone develop in a more deep cyclone circulation by this ; and an anticyclone circulation zone with more severe low potential vorticity in high - troposphere
通过对等熵面的位涡分析，发现了对流层中低层的位涡场，在气旋上方有一个相对高位涡中心，由此使得气旋在一个比较深厚的气旋性环流中发展；而对流层高层则是一个伴有较强位涡低值的反气旋环流区。 - When the tcf in nwp is high , the bengal bay cef which located at 90 e is strong and the new guinea cef located at 150 e is weak ; there is a anti - cyclonic circulation near the equator . the equatorial buffer zone is fortified : it is propitious to the equatorial anticyclones activated and push monsoon trough to higher latitude , this circulation pattern can promote the genesis of tc in nwp
多热带气旋年，位于90 e附近的孟加拉湾越赤道气流显著增强，而位于150 e附近的新几内亚越赤道气流异常偏弱；在赤道附近存在一个异常的反气旋性环流，赤道缓冲带较强，有利于赤道高压的活跃，季风槽被推向较高纬度，从而有利于热带气旋的生成。
