| 摘 要： | 本文利用1949-2006年热带气旋资料,对58a来影响和登陆浙江热带气旋的登陆位置、登陆时间的年际、月际和日变化、登陆后的移速及路径变化与降水中心分布的关系、登陆后维持和衰减情况等进行了统计分析.统计结果表明：影响和登陆浙江的热带气旋有较明显的年际、月际和日变化特征;登陆浙江的热带气旋陆上维持时间与登陆时的强度正相关,登陆后12h内热带气旋衰减较快;登陆后移向偏北分量大的或移速加快的热带气旋,主要降水区出现在路径右侧的可能性大.

| Abstract: | With tropical cyclones data from 1949 - 2006, the climatic features of tropical cyclones landed on Zhejiang, such as its landfall, sustainability, decay and the relation between move velocity or track and distribution of precipitation, etc. were studied statistically. Results indicated that the tropical cyclones which affected and landed on Zhejiang varied annually and monthly with diurnal variations. The most obvious weakening of tropical cyclones occurred after first 12h landfall, and the stronger the tropical cyclone was the longer the time it sustained. Heavy rainfall appeared on the right side of the track when the cyclones moved toward the north or when the moving velocity increased. |
