| 1 | Validation and Application of Reanalysis Temperature Data over the Tibetan Plateau显示文摘The Tibetan Plateau has substantial impacts on the weather and climate of the Northern Hemisphere,due in large part to the thermal effects of the plateau surface.Surface temperature over the Tibetan Plateau is the most important parameter in determining these thermal effects.We present a method for verifying widely used reanalysis temperature products from NCEP-R2,ERA-Interim,and JRA-25 over the Tibetan Plateau,with the aim of obtaining a reliable picture of surface temperature and its changes over the plateau.Reanalysis data are validated against the topography elevation,satellite observations,and radiosonde data.ERA-Interim provides the most reliable estimates of Tibetan Plateau surface temperature among these three reanalyses.We therefore use this dataset to study the climatology and trends of surface temperature over the Tibetan Plateau.ERA-Interim data indicate a dramatic warming over the Tibetan Plateau from 1979 to2010,with warming rates of 0.33℃ per decade in annual mean temperature,0.22℃ per decade in summer and0.47℃ per decade in winter mean temperatures.Comparison with the results of previous studies suggests that surface warming over the Tibetan Plateau has accelerated during the past 30 years.This warming is distributed heterogeneously across the Tibetan Plateau,possibly due to topographic effects. | 邹捍 朱金焕 周立波 李鹏 马舒坡 | 2014 | Journal of Meteorological Research2014，28，1： | 9 |
| 2 | 中国北方春季沙尘暴活动与高空西风急流变化的联系显示文摘利用1954-2007年中国国家气象信息中心提供的强沙尘暴序列数据集和美国国家环境预报中心与国家大气研究中心(NCEP/NCAR)提供的再分析资料,分析了30°N以北的中国北方沙尘暴活动与东亚高空西风急流变化的联系。结果表明,中国北方春季沙尘暴出现频数与亚洲大陆对流层高层200 hPa中纬度西风急流的位置和强度变化存在着密切的联系。这种关系在年际和年代际时间尺度上均得到体现,在多(少)沙尘暴活动年,急流轴位置比正常年偏北(南)。在研究时段内,沙尘暴活动呈现减少的趋势,同时高空西风急流表现出系统性南移趋势。这种相关性存在内在的联系,反映了高空西风急流轴位置变化对地面沙尘暴活动的影响:当春季200 hPa高空西风急流轴位置比正常偏南时,中国北边界至蒙古国一带的一个关键区(70°E-120°E,42.5°N-52.5°N)对流层高层西风显著减弱,该区高空急流减弱一方面通过动量下传造成沙尘源区低层西风减小,削弱沙尘暴产生所需的动力条件,另一方面使风切变和斜压性减小,不利于地面气旋的生成,从而使沙尘暴活动减少。 | 李雪 刘晓东 | 2015 | 高原气象2015，34，5： | 8 |

| 4 | Climatology of dust storms in northern China and Mongolia: Results from MODIS observations during 2000-2010显示文摘The climatology of dust storms in northern China and Mongolia(33°N–54°N, 73°E–136°E) is characterized at a 1-km resolution based on Moderate Resolution Imaging Spectroradiometer(MODIS) thermal observations during 2000–2010. The dust was extracted with the dynamic reference brightness temperature differences(DRBTD) dust detection algorithm. The major dust source regions are deserts, including the Tarim Basin, Hexi Corridor, Gobi in Mongolia and northern China, Horqin Sandy Land and Qaidam Basin. Dust storms occur most frequently in the Tarim Basin, with a maximum frequency(above 10%) in the eastern narrow inlet of the Taklimakan Desert around Lop Nor. Significant annual and seasonal variations are found for dust events. More than 63.8% of dust events occur in spring from March to May, with the maximum proportion(up to 29.6%) occurring in April. Severe dust storms occur mainly in the deserts in northern and northwestern China, and the largest source region is the eastern narrow inlet and the southern margin of the Taklimakan Desert. | LIU Yang LIU Ronggao | 2015 | Journal of Geographical Sciences2015，25，11： | 2 |
