Analysis of heavy rain caused by typhoon "Fitow" in Huzhou(台风“菲特”引发湖州大暴雨的成因分析)
Zhejiang Daxue xuebao. Lixue ban, 2014 利用MICAPS资料和中小尺度地面自动站资料，对2013年10月6~8日台风“菲特”影响湖州地区时的大暴雨过程进行分析发现，大暴雨降水分3个阶段：台风“菲特”外围云带中的强降雨、台风本体范围及边缘的暴雨和台风“菲特”减弱后的倒槽和北上近海转向的台风“丹娜丝”外围东北气流的叠加暴雨.分析可知，东北急流带来的充沛水汽、高能高湿的能量输送、强烈的上升运动和高层辐散低层辐合等为大暴雨的发生发展提供了十分有利的环境场.天荒坪山区朝东北开口并由东北向西南多级收缩抬升的地形为暴雨的增幅创造了有利条件 ...

The comparative analysis of two “7.17” torrential rainfalls in Huzhou Area(湖州地区2次“7. 17”特大暴雨过程的对比分析)
Zhejiang Daxue xuebao. Lixue ban, 2014 利用湖州市中尺度自动站资料、风廓线资料以及NCEP再分析资料对2011年7月17日和2012年7月17 日湖州地区发生的2次特大暴雨过程的降水特征、环流形势、水汽条件和动力抬升机制进行了对比分析，发现2次“7. 17”特大暴雨的发生具有偶然性也有必然性.(1)副高位置偏高，其西南侧热带气旋活跃，提供强盛偏东气流，与槽前的西南气流汇合，在副高边缘形成有利于强降水发生的天气背景.(2)偏东气流的加强对于特大暴雨的触发有至关重要的作用，可以作为判断夏季特大暴雨爆发时段的一个关键信号.(3 ...

Zhejiang Daxue xuebao. Lixue ban, 2015 应用自动站和NCEP 1°×1°再分析资料，对2010年7月24日发生在东南沿海的一次大暴雨过程的湿位涡场进行了诊断分析.结果表明：鞍形场低层东南风低空急流输送的暖湿气流和对流层中低层来自东北方向的冷空气相互交汇是此次大暴雨发生的触发因子，大暴雨期间暴雨区上空对流层中低层等θse线较稀疏且陡立，大气对流稳定度较低，有利于湿斜压涡度发展，大暴雨发生在600 hPa上MPV、MPV1和MPV2正负过渡带附近，MPV1下负上正垂直叠加配置是暴雨发生发展的有利形势，湿位涡在900 hPa以下具有MPV1为负 ...

Characteristics of rainstorm in northwestern mountainous area of Zhejiang(浙江西北部山地暴雨特征)
Zhejiang Daxue xuebao. Lixue ban, 2019 利用2005-2017 年14 个自动气象站和2015-2017 年66 个自动气象站的降水资料，对浙西北暴雨的时空分布特征进行了分析，发现浙西北雨量分布呈西南、东北多，中部、东部少的特征，有2 个暴雨中心，一个是位于清凉峰到大明山一带的梅汛期暴雨中心，另一个为天目山北部市岭一带的台风暴雨中心；暴雨存在明显的月、日变化特征，7-8 月暴雨最多，春雨期暴雨主要出现在日落后，梅雨期主要出现在早晨前后，其次是午后，盛夏时主要出现在午后；6 月前暴雨集中在西部、南部，7 月出现明显转折，西南暴雨迅速减少 ...
