1Meteorological Features at 6523 m of Mt.Qomolangma(Everest)between 1 May and 22 July 2005显示文摘Mt. Qomolangma (Everest), the highest mountain peak in the world, has little been studied extensively from a meteorological perspective, mostly because of the remoteness of the region and the re-sultant lack of meteorological data. An automatic weather station (AWS), the highest in the world, was set up on 27 April 2005 at the Ruopula Pass (6523 m asl) on the northern slope of Mt. Qomolangma by the team of integrated scientific expedition to Mt. Qomo-langma. Here its meteorological characteristics were analyzed according to the 10-minute-averaged and 24-hour records of air temperature, relative humidity, air pressure and wind from 1 May to 22 July 2005. It is shown that at 6523 m of Mt. Qomolangma, these meteorological elements display very obvious diurnal variations, and the character of averaged diurnal variation is one-peak-and-one-vale for air tem-perature, one-vale for relative humidity, two-peak-and- two-vale for air pressure, and one-peak with day-night asymmetry for wind speed. In the 83 days, all the air temperature, relative hu-midity and air pressure increased with some dif-ferent fluctuations, while wind speed decreased gradually and wind direction turned from north to south. The variations of relative humidity had great fluctuations and obvious local differences. Then thepaper discusses the reason for the characters of diurnal and daily variations. Compared with the corresponding records in May 1960, 5-day-averaged maximums, minimums and diurnal variations of air temperature in May 2005 were apparently lower.XIE Aihong REN Jiawen QIN Xiang JIANG Youyan 2006Journal of Mountain Science2006,3,3:4
2High-resolution cyclostratigraphy of geochemical records from Permo-Triassic boundary section of Dongpan,southwestern Guangxi,South China显示文摘Spectral analysis is applied to geochemical data from a deep-water Permian-Triassic Boundary (PTB) section across PTB in Dongpan, Guangxi for high-resolution cyclostratigraphic research. The characteristics of the Milankovitch Cycles have been well recorded in the strata of the Dongpan section. Spectrum on Ce/La records shows especially that the ratios among its three preponderant cycles in the section are 5:2:1, which well displays the phenomenon of the sedimentary cycles driven by orbital force. The Milankovitch theory is further confirmed by the Paleozoic records.PENG XingFang FENG QingLai Li ZhouBo MENG YouYan 2008Science China Earth Sciences2008,51,2:4
3Meteorological observations on Mount Everest in 2005显示文摘山珠穆琅玛,地球上的最高的点是经常被指地球如此的这个地方相对无法接近、小的第三杆对它的气象学被知道。在 2005 年 4 月,一个自动气象站作为山的诺思关口被安装(6523 m 一。s。l.) 。根据观察 10 分钟的吝啬、每日的记录,气象学的特征被分析。所有气象学的元素显示了明显日报变化在到 2005 年 7 月 22 日的 5 月 1 日期间。山珠穆琅玛上的每日的气象学的元素的每月的变化在 Dingri 上与那与一致,最近平淡的气象学的车站与 0.928 的高关联系数, 0.877 , 0.682 , 0.755 , 0.826 和 0.676 ( n = 83 , p < 0.001 )为吝啬的温度,最小的温度,最大的温度,相对湿度,压力和风分别地加速。而且,温度的垂直吝啬的坡度在 0.6 ° C /100 m 上面,特别为每天最大的温度。山珠穆琅玛上的大多数天气事件显著地在 Dingri 上出现在象那些的一样的天,特别那些与 0.673, 0.485 和 0.487 的跨关联的系数从每天意味着压力,温度和相对湿度(n = 83, p< 0.001 ) 分别地。山珠穆琅玛上的一些另外的天气事件落后 Dingri 上的在那些后面的一天。而且,在 Dingri 上从压力在山珠穆琅玛上天气事件预报是比从另外的气象学的元素的那些更可靠的。结论在这个区域为关于气象学和气候变化的研究是重要的。Xie Aihong Qin Dahe Ren Jiawen Qin Xiang Xiao Cunde Hou Shugui Kang Shichang Yang Xingguo Jiang Youyan 2007Progress in Natural Science:Materials International2007,17,7:2
