摘要:

利用NCEP的FNL(Final Reanalysis Data)和GDAS(Global Data Assimilation System)再分析资料、中国气象观测网降水实况数据及基于拉格朗日方法的HYSPLIT轨迹模型结果, 对2019年8月13—17日发生在中国东北地区一次减弱台风引发暴雨过程的水汽条件和输送过程进行分析。结果表明: 此次中国东北地区暴雨的水汽与源自西太平洋的水汽关系最为密切, 台风“利奇马”为本次暴雨的主要水汽供应系统, 其次是台风“罗莎”外围水汽补充。拉格朗日方法的水汽输送源主要有3个, 分别为源于中低纬西太平洋, 与欧拉方法的太平洋和黄海水汽相对应; 源于中国南海南部, 与印度洋水汽相对应; 源于黑龙江北部, 中国北方的水汽对暴雨也有一定作用。中国南海南部水汽与西太平洋水汽合并, 为此次东北地区暴雨的主要水汽供应。水汽收支主要集中在中低层, 水汽的辐合区主要位于700~900 hPa。低层的水汽垂直向高层输送, 水汽的辐合和垂直输送越强, 降水量越大。水汽流入集中在低层的南边界, 西边界和北边界一般为水汽流出边界。

Abstract:

Using the reanalysis data of FNL (Final Reanalysis Data) and GDAS (Global Data Assimilation System) from the NCEP (National Center for Environmental Predictions), the precipitation data from China Meteorological Observation Network and the results of HYSPLIT (HYbrid Single-Particle Lagrangian Integrated Trajectory) model based on the Lagrange method, the water vapor conditions and transport process of a rainstorm triggered by a weakening typhoon in Northeast China from August 13 to 17, 2019 were analyzed.The results show that the water vapor in Northeast China is most closely related to the water vapor from the Western Pacific Ocean.Typhoon "Lekima" is the main water vapor supply system for this rainstorm, followed by Typhoon "Krosa".There are three main water vapor transport sources in the Lagrange method, which come from the western Pacific in the middle and low latitudes, respectively, corresponding to the Pacific and Yellow Sea in the Euler method.It originates from the South China Sea and corresponds to the Indian Ocean.Water vapor from northern Heilongjiang and northern China also plays a role in the rainstorm.The southern water vapor in the South China Sea and the western Pacific merge, which is the main water vapor supply for the rainstorm in Northeast China.The water vapor budget is mainly concentrated in the middle and lower layers, and the convergence zone of water vapor is mainly located between 700~900 hPa.The water vapor in the lower layer is transported vertically to the upper layer, and the stronger the water vapor convergence and vertical transport, the greater the precipitation.The water vapor inflow concentrates on the southern boundary of the lower layer, while the western and northern boundaries are generally the water vapor outflow boundary.
