摘要:
利用常规气象资料、卫星云图及区域自动站等资料，对2018年第9号台风"山神"残留系统再次生成热带低压的原因及其移动路径进行分析。结果表明，北部湾低压形成的原因主要有两方面，一是西南季风不断供应水汽和能量使其维持螺旋结构，二是北部湾海面温度较高；第二类条件不稳定机制使热带扰动不断发展；对流层垂直风切变小，使对流降水释放的凝结潜热积聚而导致低层减压；高层辐散、低层辐合，导致气旋性涡度增加。受热带辐合带南侧偏西风和台风"安比"的互旋作用影响，北部湾低压先后往东偏南、东北、西北方向移动。
Abstract:
Using conventional meteorological data, satellite cloud images and regional automatic stations, this paper analyzed the causes and moving path of the tropical depression regeneration of the residual system of Typhoon No. 9 Son-Tinh in 2018. The results showed that there were two main reasons for the formation of the Beibu Gulf depression:one was the continuous supply of water vapor and energy by the southwest monsoon to maintain its spiral structure, and the other was the high sea surface temperature in the Beibu Gulf. The second type of conditional instability mechanism made the tropical disturbance develop continuously. The tropospheric vertical wind shear became small, which made the condensation latent heat released by convective precipitation accumulate and led to low-level decompression. High-level divergence and low-level convergence led to the increase of cyclonic vorticity. Affected by the interaction of the westerly wind on the south side of the tropical convergence zone and Typhoon Ampil, the Beibu Gulf depression moved to the south by East, northeast and northwest successively.
