使用常规观测、最佳台风路径数据、风云二号气象卫星亮温（Black body temperature equivalent，TBB）、全球协同探空站资料和NCEP/NCAR全球再分析资料，对2016年第10号台风"狮子山"并入温带气旋过程中，二者相互作用下引发的东北地区强降水进行了分析。结果发现，台风"狮子山"并入温带气旋过程中，其结构由对称的热带涡旋云系向非对称斜压云系发展，最终演变为成熟的温带气旋云系。受温带气旋的影响，台风"狮子山"逐渐进入到强垂直风切变环境，台风涡旋环流、水汽输送、垂直运动呈现明显的不对称和垂直向西倾斜结构，暖心结构遭遇破坏，水汽输送逐渐远离台风环流；台风影响下的高低空急流有利配置对温带气旋形成正涡度平流输送，伴随着锋生作用，使得温带气旋获得动力和能量而发展。对东北地区强降水的分析发现，台风并入温带气旋过程中，温带气旋加强发展，带来了增强的动力、水汽和能量的输送，是引发东北地区强降水的主要原因，降水主要发生在暖平流带中，600 hPa与900 hPa之间的厚度梯度大值区对强降水的落区具有很好的指示，强低层辐合、高层辐散，促使强的垂直上升运动，配合强暖平流和充沛水汽的输送，对应着强降水的发生。高层弱的干冷空气缓慢向低层侵入，使得降水持续时间长、结束缓慢。降水总体具有持续性，伴有较强对流降水的发生。
Based on conventional ground data, typhoon best track from Shanghai Typhoon Institute, sounding data, black body temperature equivalent (TBB) of FY-2 meteorological satellite from National Satellite Meteorological Center, and high-resolution NCEP/NCAR global reanalysis data, the physical development mechanism and strong precipitation mechanism in Northeast China during typhoon Lionrock (1610) merging into extratropical cyclone process was analyzed. The result indicated that symmetric tropical cyclone cloud system developed into asymmetric baroclini cloudsystem, and finally evolved into mature extratropical cyclone cloud system. Meanwhile, Lionrock entered into the strong vertical wind shear environment gradually, and typhoon vortex circulation, water-vapor transfer and vertical movement showed remarkable asymmetric and vertical westward tilt feature. Furthermore, warm-core structure was destroyed, water-vapor transfer gradually went away from typhoon circulation. Under the interaction between upper and low-level jet, extratropical cyclone appeared obvious frontogenesis for the positive vertical vorticity advection, which enhanced the development of extratropical cyclone. Under the co-effect of Lionrock and extratropical cyclone, enhanced dynamic, water vapor and energy transport caused by development cyclone, was the main reason for the heavy rain in northeast China. It was found that precipitation in Northeast China mainly occurred in warm advection, high value of thickness gradient had good direct a indicative function. It was also found that heavy precipitation was influenced by strong upper levels divergence and low levels convergence of dynamic and water vapor, meanwhile corresponded to strong temperature advection and vertical upward motion. Long time duration of rainfall and ending slow, was related with weak dry cold air intrusion from high to low level slowly. The precipitation process was sustainability, with relatively strong convective precipitation occurring locally.
