Northern China maximum temperature in the summer of 1743： A historical event of burning summer in a relatively warm climate background

In the context of historical climate records of China and early meteorological measurements of Beijing discovered recently in Europe, a study is undertaken on the 1743 hottest summer of north China over the last 700 a, covering Beijing, Tianjin, and the provinces of Hebei, Shanxi and Shandong, with the highest temperature reaching 44.4℃ in July 1743 in Beijing, in excess of the maximum climate record in the 20th century. Results show that the related weather/climate features of the 1743 heat wave, e.g., flood/drought distribution and Meiyu activity and the external forcings, such as solar activity and equatorial Pacific SST condition are the same as those of the 1942 and 1999 heat events. It is noted that the 1743 burning summer event occurs in a relatively warm climate background prior to the Industrial Revolution, with a lower level of CO2 release.     

一株海洋弧菌噬菌体--VP9的分离和特性研究

1997年夏季，从皱纹盘鲍脓疱病发病区采集海水样品58份，以河流弧菌Ⅱ(vibrio fluvialis-Ⅱ)为指示菌，从这些样品中分离出多株噬菌体，对其中VP9进行了电子显微镜观察分析，并对其生物学特性进行了初步的研究,结果表明：VP9具有典型的廿面体头部及具有尾鞘的尾部．并具有尾椎．VP9对热敏感，热稳定性较差，在65℃，5min内全部失活,在pH6～12之间有较高的稳定性.     

北京地区夏季中间尺度云团形成的环境特征

使用对比度分析方法对影响北京地区夏季的中间尺度云团形成的环境特征及其与强天气的关系进行详细分析,研究得出６～８月云团发生具有局地强风暴和暴雨的综合环境特征,加深了对中间尺度云团的了解,对改进强天气的预报有参考意义     

井冈山自然保护区夏季鸟类多样性分析

1994～2001年夏季对井冈山自然保护区的鸟类资源进行了考察，共记录到鸟类125种，隶属于15目，37科，对鸟类的区系组成、生态类群及数量进行了研究，该地的夏候鸟25种，留鸟82种，冬候鸟16种，旅鸟2种，东洋界鸟类67种，古北界鸟类28种，广布性鸟类30种，国家一级保护鸟类2种，二级14种；有重要经济、科研价值的鸟类83种。     

Summer sea-surface temperatures and climate events on the North Icelandic shelf through the last 3000 years

Diatom data from core MD992271 on the North Icelandic shelf record a cooling trend through the last 3000 years. This is indicated by a general decrease in warm water species and an increase in cold water taxa. The relative abundance of these two diatom groups changed periodically, suggesting that the climate also fluctuated within this time period. The results of diatom-based transfer function calculation show that the summer sea-surface temperatures (SSTs) before 1400 cal. a BP were generally higher than the mean value for the last 3000 years and the summer SSTs fluctuated around the mean between 1400 and 700 cal. a BP, and dropped to the values below the mean after 700 cal. a BP. Four cooling events were distinguished, centered at around 2600, 1900, 1300 and 600 cal. a BP respectively. The results are not only consistent with the data from neighbouring cores HM107-03 and MD992275, but also comparable with those from the GISP2 ice core and from other marine sediment records in the North Atlantic. This suggests that changes in the summer SSTs reflect regional climate variations in the North Atlantic. On the North Icelandic shelf, the summer SST variation is a result of changes in the in-teraction between the cold and the warm currents in the area.     

青藏高原冬季NDVI变化与我国夏季降水的关系

利用1982年1月—2001年12月NDVI资料、台站降水资料和NCEP/NCAR再分析资料,通过相关分析和合成分析等方法,初步分析了青藏高原冬季植被变化与我国夏季降水的关系.结果发现,高原冬季植被多少与我国夏季降水存在明显的相关关系.高原冬季NDVI大时,我国华南地区、华北地区等夏季降水偏多,而长江流域(主要是中游地区)和西南地区西北部、东北地区西部降水偏少.高原冬季NDVI与我国夏季降水的相关系数从南到北,总体呈西北-东南向" - -"带状分布.降水的年内分布也因为不同年份NDVI的多少而存在较明显的差异,后期的大气环流变化能够较好地解释我国夏季降水的这种差异.
