- 摘要:
- 为了提高华东地区台风暴雨的预报水平,利用ECMWF再分析资料(0.75×0.75)、FY-2E卫星TBB资料、雷达资料、全国自动站逐小时降水资料等资料对台风“玛莉亚”强降水时段的降水特征进行分析并对其成因进行初步探讨,结果表明:台风“玛莉亚”降水主要集中在台风内核及外围螺旋雨带上,东南低空急流和持续的水汽输送为台风降水提供了良好的动力和水汽条件; 主体内核附近零散对流回波组织成块影响降水,其剖面与山脉起伏具有一致性,同时具有质心较低,降水效率高的特点; 海上的β中尺度线状对流沿台风切线方向移动,不断经过温州地区造成降水,对流单体质心较低且向前倾斜,易产生以短时强降水为主的强对流性天气; 台风内核降水集中在福州和建宁地区,福州地区充沛的水汽配合地面辐合线和山脉抬升触发强降水发生; 建宁地区,山脉抬升、中尺度切变线配合密集温度梯触发强降水。外围螺旋雨带的强降水主要位于温州地区,地面辐合线是降水的主要触发机制,同时对降水具有较好的指示作用。通过对“玛莉亚”的分析为华东地区台风暴雨的预报提供了有利的参考依据。
- Abstract:
- In order to improve the typhoon rainstorm forecast level in east China area, using ECMWF reanalysis data(0.75×0.75),FY-2E satellite TBB data,radar data,the automatic station precipitation data as well as the national regional automatic station hour by hour observation data,analyzing the precipitation characteristics of typhoon “maria” in the period of heavy rainfall,initially discussing its cause,the results showed that:The precipitation of typhoon maria was mainly concentrated on the spiral rain belt of the typhoon’s core and periphery.The southeast low-altitude jet and continuous water vapor transport provided good power and water vapor conditions for the typhoon’s precipitation.The scattered convection echo near the main core is organized into blocks to affect the precipitation,and its profile is consistent with the fluctuation of mountains, with characteristics of a low center of mass and high precipitation efficiency.The horizontal mesoscale linear convection on the sea moves along the tangential direction of the typhoon and continuously passes through Wenzhou area, causing precipitation.The convective monomer centroid is low and leans forward, which easily leads to the strong convective weather dominated by short-term heavy rainfall. The precipitation in the core of the typhoon was concentrated in Fuzhou and Jianning areas. The abundant water vapor in Fuzhou region triggered the heavy precipitation with the ground convergence line and the mountain rise.In Jianning area, the mountain uplifts and mesoscale shear lines are combined with dense temperature ladders to trigger heavy precipitation.The heavy precipitation in the outer spiral rain belt is mainly located in Wenzhou area.The ground convergence line is the main trigger mechanism of precipitation,it also give an instruction for the precipitation.The analysis of maria provides a reference for the forecast of typhoon and rainstorm in east China.
