| 摘 要： | 利用天气实况和NCEP再分析资料，对2004年8月26—28日山东大暴雨过程进行了客观分析。结果表明，0418号热带气旋在福建沿海登陆后，其北伸倒槽与西风带弱冷空气结合造成了本次大暴雨过程，具有明显的中低纬系统相互作用特征。伴随登陆热带气旋生成的低空东南急流为暴雨输送了丰富的热量和水汽，成为联系中低纬度系统的纽带。西风带弱冷空气侵入台风北伸倒槽后，在黄淮之间有明显的暖锋锋生特征，是触发倒槽区域中尺度对流发展和暴雨产生的重要动力机制。暴雨与高能舌区具有很好的对应关系，总能量分布对热带气旋远距离暴雨的落区具有很好的指示作用。 |
| 关 键 词： | 热带气旋倒槽 低空急流 中低纬系统相互作用 大暴雨 |

| Abstract: | Based on the observational data and NCEP reanalysis data, the heavy rainfall event on 26--28 Aug 2004 in Shandong Province is diagnostically analyzed. The result shows that the event is caused by the interaction between 0418 tropical cyclone trough landed in Fujian Province and a weak cold front in the westerlies, it has obvious interacting characteristics be tween the two weather systems. The low-level southeast jet accompanying the tropical cyclone transports a plenty of heat and moisture for the event. It plays an important role instimulating the convection that the weak cold air intrudes the area of the inverted trough, and conduce to warm frontogenesis, thus leading to the heavy storm. The heavy rain mainly distributed in the tongue area of high energy, the total energy is a key index to predict the rainfall area related to distant onland tropical cyclone. |
| Keywords: | tropical cyclone trough low-level jet interaction between middle-and low-latitude systems heavy rainfall |
