晨六点起。大雨不止,平地尽成泽国。阅来往信件四十余件。十点前农学院(东大)毕业杨继义来,现在江西办青年军就业训练班农业部份,地点在江西铅山。
  此次借青年军卅一车政治部副主任黄贤虔来,道中谓在绿杨新村及净寺办理法律、交通、师范、电机等各班训练班,请介绍人才。中午据次廉报告,谓省立图书馆有保安队兵士一总队开入居住。余于中膳即嘱皮高品往图书〔馆〕告兵士以该屋已有省政府交与浙大,不日修理,不能居住。一方嘱杨次廉去接洽队长。余睡一小时后,三点即借季梁至岳坟前市政府小学地址看地。此处有地一亩八分,可以建筑师范学院之学生宿舍,但沿湖长不达一百码。四至圣塘路晤丝鸣涛,嘱令宪兵搬走。
  ”Radar and Weather” by R. H. Maynard , lournal 0/ Met. Dec. 1945 , p. 215.Storm types detectable by radar are showers , squall lines , thunderstorms , coldfronts , warm fronts , < occulded) [occluded) fronts , Typhoons and Tornadoes. Rangesat which these storms can be detected depend on their vertical extent. For storms ofm∞, vertical extent only 8 miles; 10 ,000' , 120 miles and 20 ,000' , 175 miles.The characteristics on a PPI (plan position indicator) are as follows: Showers , onPPI scopes showers have poorly defined edge and show a hazy character, generally withwinds. Squall lines , similar to showers show a band arrangement. Thunderstorms , v町easily detected , on PPI scope appears as a bright dense central area with distinctboundaries. The maximum angle of elevation at which the echo is received gives a rough171measure of the height of thunderstorm. Cold fronts appears as a zone of well definedechoes moving across the field of PPI scope. The echoes may join or break up. Warmfronts echoes are indistinct and cover wide areas , occluded fronts produces an echo similarto warm fronts. Typhoons , eye of storm appears as dark area , sUITounded by curvedbands , with feathered edges , very unmistakable.接高直侯二函陈令仪、方正三、留黔同学会、匿名攻击金维坚函金公亮、王金陵函金咏深、谢幼伟、薛良叔、晓峰二函金梵音、宁宁、羽仪太太二函俞心湛二函振公二函黄尊生、默君、莫葵卿、姜容熙、贺师俊、崔东伯、楼光来、蔡谅友函谢屡电
