- 摘要:
- 为更好地分析极端异常北上台风“美莎克”的影响机制,利用ERA5 0.5°×0.5°逐6 h再分析资料,FY-2G卫星资料,NCEP再分析资料及东北地区常规气象观测资料,就台风北上过程的大尺度环流背景、动力、热力、水汽条件等方面进行诊断分析。结果表明,西太平洋副热带高压与鄂霍茨克海上的高压脊合并加强、稳定维持是造成“美莎克”北上的主要原因,与西风带低涡相互作用使得台风持续时间较长,台风结构在与西风带系统逐渐融合且北上的过程中强度逐渐减弱,雨强也随之迅速减弱。高空急流的抽吸作用及低层辐合、高层辐散的配置,使降水稳定维持,3条水汽通道的建立使多地区出现台风暴雨,物理量条件的非对称性分布造成了降水的非对称性。台风登陆前后不稳定性有所变化,登陆后短时间内不稳定性增强对应着降水的增幅,登陆后主要以稳定性降水为主。干冷空气入侵初期增强了降水不稳定性,冷空气的深入使台风暖心结构遭到破坏,随后减弱变性。
- Abstract:
- In order to better analyze the impact mechanism of the extremely abnormal northward typhoon “Maysak”, based on ERA5 0.5°×0.5° 6 hourly reanalyzed data, NCEP reanalyzed data, the conventionally observed data, FY-2G satellite data,analyzed the large scale circulation background、power、heat and moisture conditions, etc. The results show that Strengthen, stability of the Western Pacific subtropical high and Okhotsk blockinghigh was the main cause of “Maysak” always toward the north, interaction with the westerlies low vortex makes a longer duration of typhoon, precipitation intensity weakened as the typhoon weakened. Jet pumping function, the configuration of low-level convergence and high-level divergence makes steady rainfall,the establishment of three water vapor channels makes many regions appeared typhoon heavy rain,the asymmetry of precipitation due to the asymmetry distribution of physical conditions. The instability changes during the typhoon landfall, the increase in instability in a short period of time after landfall corresponds to the increase in precipitation. the precipitation is mainly stable after landfall. Dry cold air initial invasion increased the instability, warm heart structure was destroyed, the typhoon weakened with the constant intrusion of cold air.
