By using global reanalysis data from NCEP/NCAR,the durative of a floating dust over Beijing during 7-10 in April of 2006 was analyzed.It was found that the impact systems of the floating dust weather were West Siberia cold eddy,Okhotsk warm high and Tibetan Plateau high ridge at the level of 500 hPa;the dry-cold air at the level of 700 hPa transferred to Beijing ceaselessly,and the cold advection and baroclinic instability were strong,the gale and dust storm occurred in the strong cold advection area;the weak instability stratification in surface layer and mid-low level in the south of North China resulted in weak ascending air flow,then transported dust particles to Beijing depending on the easterly wind in front of the surface low pressure.

文章摘要：使用NCEP/NCAR再分析资料对2006年4月7-11日北京浮尘天气过程的持续性进行分析，指出此次浮尘天气过程主要受500 hPa西西伯利亚冷涡、鄂霍次克海暖高压以及青藏高原高压脊影响；700 hPa有干冷空气不断向北京地区输送，冷平流和斜压性都很强，大风和沙尘暴发生在强冷平流区域；由于华北南部地区近地面至中低层存在弱的不稳定层结，容易产生弱的上升运动。

Reference crop evapotranspiration (ET0) and new wetness index were both calculated and analyzed according to Penman-Monteith scheme recommended by FAO with routine meteorological data from 616 weather stations in China from 1975 to 2004. In terms of grades of wetness index from Chinese Climate Classification Criterion, China is classified into severe arid, arid, semi-arid, semi-humid and humid zones, respectively, which are compared with the demarcations from rainfall-based indices in order to reveal the similarity and difference in association with the two schemes under current global climate warming. Besides, the spatio-temporal analysis of climate wetness over the country in the past thirty years was performed.

依据中国616个地面气象台站1975年至2004年的日气象资料，利用联合国粮农组织推荐的参考蒸散计算方法，计算参考作物蒸散（ET0）和湿润指数，按照中国气候区划中的干湿指标把中国分为极干旱、干旱、半干旱、半湿润和湿润气候区，并与传统的降水量干湿指标进行对比，揭示在全球气候变化下两种干湿指标的异同，最后对中国近30 a干湿状况进行时空分析。
