| 1 | Simulation evaluation and future prediction of the IPCC—AR4 GCMs on the extreme temperatures in China显示文摘On the basis of the temperature observations during 1961-2000 in China,seven coupled general circulation models'(GCMs)extreme temperature products are evaluated supplied by the Intergovernmental Panel on Climate Change's 4th Assessment Report(IPCC-AR4).The extreme temperature indices in use are frost days(FD),growing season length(GSL),extreme temperature range(ETR),warm nights(TN90),and heat wave duration index(HWDI).Results indicate that all the seven models are capable of simulating spatial and temporal variations in temperature characteristics,and their ensemble acts more reliable than any single one.Among the seven models,GFDL-CM2.0 and MIROC3.2 performances are much better.Besides,most of the models are able to present linear trends of the same positive/negative signs as the observations but for weaker intensities.The simulation effects are different on a nationwide basis,with 110°N as the division,east(west)of which the effects are better(worse)and the poorer over the Qinghai-Tibetan Plateau in China.The predictions for the 21st century on emissions scenarios show that except decreases in the FD and ETR,other indices display significant increasing trend,especially for the indices of HWDI and TN90,which represent the notable extreme climate.This indicates that the temperature-related climate is moving towards the extreme.In the late 21st century,the GSL and TN90(HWDI)increase most notably in southwest China(the Qinghai-Tibetan Plateau),and the FD decrease most remarkably in the Qinghai-Tibetan Plateau,northwest and northeast of China.Apart from South China,the yearly change range of the extreme temperature is reduced in most of China. | WANG Ji JIANG Zhihong SONG Jie LOU Dejun | 2008 | Acta Oceanologica Sinica2008，27，3： | 2 |
| 2 | Inhomogeneity characteristics of snow in Northeast China显示文摘在东北中国基于 19612005 观察冬季降水数据,雪集中度(SCD ) 的时间、空间的变化和雪集中时期(SCP ) ,和发行量特征当有更高的 SCD 时,被计算并且分析。结果证明在东北中国的 SCD 介绍一个每年升起的趋势, SCP 显然减少。以十的变化,在 PCP 有一个 12 年的周期的变化,并且自从 mid-1970s,有一个 8 年的短周期的变化。至于空间变化,在东北中国的冬季的 SCD 从东方部分逐渐地增加了到西方,并且 SCD 的最小的价值发生在吉林省的东方,当高价值中心在省的中央部分被观察时。为整个东北中国,变化趋势在东方、中央的部分是一致的,在 SCD 介绍一个升起的趋势, SCP 显示出一个减少的趋势的地方。在西南、北的部分的 SCD 有一个细微升起趋势,与在有在显示出最细微的减少趋势的北部分的最细微的增加趋势,和 SCP 的西南的部分的 SCD。当高 SCD 价值被观察时,整个区域被东方亚洲深马槽在 500 hPa 控制,并且当一个高压力,它是容易在东方部分形成了并且加强时,马槽在西方的部分深处变得,慢慢地使东方亚洲深马槽移动东方。上层的喷气溪流和低级喷气溪流共存,并且前者更强壮并且比后者一个向西南的位置拿更多。水蒸汽运输在上的高价值地区和平显然被加强,并且程度也增加。东北中国被沿着高价值中心的北方搬运到西北的水蒸汽影响。 | WANG Ji ZOU Liyao ZHAO Chunyu LOU Dejun | 2011 | Journal of Geographical Sciences2011，21，4： | 0 |
