- 摘要:
- 为了解持续性异常降水的天气过程,利用NOAA提供的逐日降水数据和欧洲中心提供的逐日气象数据集,分析了2016年6月10-17日华南地区持续性降水过程的降水实况和相应的环流特征及物理量场。结果表明:(1)此次降水过程中,华南大范围地区累计降水量超过100 mm,相当于日总降水量在10 mm以上,逐日降水大值区从东南逐渐往西北方向移动;(2)200 hPa上南亚高压的东伸以及高空急流南侧气流拖曳产生的切变而形成反气旋,使华南地区高空处于辐散场中; 500 hPa上西太平洋副热带高压(简称副高)缓慢北移,其西北侧与北上的暖湿气流汇合带动水汽在华南交汇,华南地区降水区位于副高西北侧;(3)700 hPa低层南支槽前暖湿气流稳定维持,整层水汽通量矢量的输送大值区与850 hPa西太平洋反气旋西北侧配合良好,孟加拉湾和南海为此次持续性降水过程提供了充足的水源;(4)高低空配置呈现为一深厚系统,有利于此次持续性异常降水的发生、发展和维持。
- Abstract:
- In order to understand the weather process of persistent abnormal precipitation, the daily precipitation data provided by NOAA and the daily meteorological dataset provided by ECWMF were used to analyze the process of persistent abnormal precipitation over South China from June 10-17, 2016 and the corresponding circulation characteristics and physical quantity fields. The results show that:(1)During this precipitation process, the accumulated precipitation in many regions of South China exceeded 100 mm, which is equivalent to that a total daily precipitation is morethan 10 mm.The large daily precipitation areas gradually moved from the southeast to the northwest.(2)At 200 hPa, the eastward extension of the South Asian High and the shear caused by the airflow drag on the south side of the upper-level jet formed an anticyclone, which made the upper air in South China in the divergent field. At 500 hPa, upper Western Pacific Subtropical High(hereinafter referred to as the “subtropical high”)slowly moved northward, and convergence of the warm and wet airflow in the northwest side of the subtropical high drives the water vapor to converge over South China. The rain-band over South China is located on the northwest side of the subtropical high.(3)At 700 hPa, the warm and wet airflow in front of the south branch trough is maintained steadily. The large value area of water vapor flux vector in the whole layer cooperates well with the northwest side of the 850 hPa western Pacific anticyclone. The Bay of Bengal and the South China Sea provide sufficient water source for this persistent precipitation process.(4)The high and low altitude configuration presents a deep and profound system, which is beneficial to the occurrence, development and maintenance of this persistent abnormal precipitation.
