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 ...

Shuitu Baochi Xuebao, 2020 为探究降雨和土地利用对南方赤红壤坡面侵蚀特征的影响，通过天然降雨观测试验，定量分析不同土地利用方式（坡耕地、果园、人工草地和撂荒地）下坡面径流和侵蚀泥沙特征，探讨降雨类型及土地利用对坡面侵蚀产沙的影响以及降雨特征参数与坡面水沙指标间的关系。结果表明：（1）2018年研究区降雨主要集中在5—9月，且每月降雨量主要由一场或几场暴雨及大暴雨组成；（2）坡耕地坡面年径流量和年侵蚀量均最大，分别是果园、人工草地以及撂荒地处理下的3.4，8.0，6.0倍和340.5，1 605.3，1 720.3倍；（2）次降雨下，

Documents about a Farmhouse in Yamashiro Area near Kyoto City (2) [PDF]
, 2007 本史料は、現京都府城陽市水主の木村正昭家文書に残された『万歳書続実記』を翻刻したものである。そのうち、今回は明治20年〜明治28年のものを掲載した。本史料の内容を大別すると、(1)木村家の農業経営についての記載、(2)周辺地域や日清・日露戦争などの社会的動向に関する記載、という二点を挙げることが出来る。そして木村家では、三年ふさがりという暦を用いた占いを、作物の売買(及び栽培)の指標として重視していた。近代南山城地域の農家経営の実態をうかがえる史料である。なお、解題を77号に掲載した。併せて参照頂きたい。

Zhejiang Daxue xuebao. Lixue ban, 2015 利用NCEP再分析资料、MICAPS资料、常规自动站资料对台风“麦德姆”过程进行综合分析，主要对其在浙江中南部和西部造成的暴雨成因作诊断分析.结果表明：(1)副高外围气流为麦德姆移动路径起着关键的引导作用；(2)暴雨区上空较强的水汽通量、高温高湿的湿能量积聚、不稳定的大气层结以及持续长时间的上升运动都为暴雨发生提供了有利条件；(3)根据湿位涡分析，本次过程是一次对流不稳定和斜压不稳定均存在、以对流不稳定为主的台风暴雨过程.暴雨区发生在MPV1负值中心附近，尤其700 hPa的MPV1值指示效果最好 ...
