Method of inverting mesocyclone circumfluence field with a single Doppler radar;
单多普勒天气雷达反演中尺度气旋环流场的方法
With research results concerned with mesocyclone for reference,especially the related content of MDA(Mesocyclone Detection Algorithm) from NSSL(National Severe Storm Laboratory),we present an improved MDA and the mesocyclone identification module in the Doppler Weather Radar Second Production software.
借鉴国内外中尺度气旋识别算法的研究成果特别是NSSL(National Severe Storm Laboratory)的中尺度气旋识别算法,结合多普勒天气雷达二次产品软件的特点,提出了改进的中尺度气旋识别算法,以动态链接库的形式,设计完成了中尺度气旋识别模块。
Each storm had a mesocyclone,wherein the flow converged cyclonically at the low level,rotated cyclonically at the middle-low level,diverged cyclonically at the middle-up level,and diverged at the up level.
结果表明,风暴中存在中尺度气旋,中尺度气旋低层气旋性辐合、中低层纯气旋性旋转、中上层气旋性辐散、高层辐散。
Moreover,the asymmetric structure of the meso-scale cyclone is closely related to the mesoscale characteristics of its wind,vorticity,divergence and so on.
结果表明:江淮暴雨过程中的中尺度气旋在发生、发展、变化过程中其结构具有不对称性,因而进一步造成了局地降水强度和分布的不均匀性。
The heavy rainstorm appeared in the front of a 500 hPa trough near the shear line of a depression on the 700 hPa, happened in the superposed zone between the right divergence area around the entrance of the upper-troposphere jet and the left convergence area of the lower-troposphere jet, and was related with the mesoscale cyclone on the surface.
结果表明:这次过程出现在500hPa槽前和700hPa低涡暖式切变线附近;强风暴发生在高空急流入口区右侧辐散和低空急流左前侧辐合重叠区,与地面中尺度气旋活动紧密相关;证实了地面中尺度气旋是由高低空急流耦合产生的次级环流引起,次级环流控制着中尺度系统发展变化。
Results show that the rain can be attributed to the northward movement and development of a tropical mesoscale cyclone.
结果表明 ,这次过程是热带中尺度气旋北上发展造成的 ;地面冷空气侵入西移的中尺度低压所导致的对流发展 ,是热带中尺度气旋发展的原因 ;大尺度环境场丰富的水汽输送为强对流的发展和维持提供了能源保障 ;地面中尺度低压中心和与其配置的切变线上的波动点对降水落区有指示意
