That did not surprise me until professor lim yean leng director of singapore ' s prestigious national heart centre , my old friend from catholic high school , came to visit me in beijing this week and showed me the newspaper clippings and magazine articles on professor cui qi . then it dawned on me that prof cui had spent his formative teenage days in hong kong before going to the united states 直到这个星期,公教中学的老校友林延龄医生新加坡全国心脏中心主任到北京来找我,并带来了关于崔琦教授的报章和杂志剪报,我才开始明白崔教授赴美国之前的少年形成时期是在香港度过的！

The ncep / ncar global reanalysis data about 55 yean ; ( 1948 - 2002 ) , the observed data about 2 years ( 1999 - 2000 ) , the meiyu data in the mid - lower reaches of the yangtze river and the precipitation data at 160 stations in china duing 1951 to 2000 are used in the paper . we present a preliminary study on the relationship between the precipitation total for meiyu and the summerly precipitation in the eastern side of the northwest china . then using nonhydrostatic version mm5 with one nested grid , the effect of the circulation patterns for meiyu on the summerly precipitation in the eastern side of the northwest china was simulated by numerical simulation of full physics 本文采用1948 2002年ncep再分析资料、 1999 2000年的全球地面、高空观测资料、 1951 2000年梅雨以及全国降水量资料，初步研究了长江中、下游地区梅雨事件与西北地区东部夏季降水的联系，并用mm5中尺度非静力模式模拟了多(少)梅雨环流型对西北东部夏季降水的影响；另外，还分析了梅雨与四川盆地、东南沿海地区夏季降水的联系。
