中文摘要	利用2010年9月1日至2014年7月31日塔克拉玛干沙漠南缘策勒流沙地的风沙气象站观测的风速、大气相对湿度、气温和太阳辐射能同步观测数据,运用回归分析、统计法、相关分析等研究方法分析了起沙风出现的时间段、起沙风持续时间以及与平均风、温、湿、太阳辐射能之间的相关性,探讨沙尘天气下气象要素相互影响机制,为沙尘天气的预测提供理论依据。结果表明,一天中超过0.5 h的起沙风在12:00(北京时,下同) 13:00时间段出现的频率最高,占总频率的8.78%, 10:00 18:00的频率占总频率的57.94%,从早上到晚上呈现先上升后下降的趋势,与气温的日变化趋势基本一致。起沙风持续时间在2~2.5 h时间段的频率最高,占13.62%。流沙前缘的月平均风速与月平均气温呈显著线性同向变化关系,月平均湿度和月平均气温呈反向变化。平均垂直风速差、垂向温度差、垂向湿度差在0.01水平上呈显著相关性,平均风速与起沙风持续时间在0.01水平上呈显著正相关性,平均风速、平均湿度与平均垂向湿差均呈显著负相关性,平均气温与平均相对湿度在0.01水平上呈极显著负相关性。平均垂直温度差与垂直风速差之间呈极显著负相关,平均垂直温度差与垂直湿度差之间呈极显著正相关性。除了0.5 m高度平均风速外,太阳辐射能均与其余气象要素之间呈极显著相关性。策勒流沙前缘的沙尘天气主要发生在春夏季,起沙风主风向以WNW、W风向为主,应加强绿洲外围WNW、W方位的防沙措施。
英文摘要	Wind velocity (V), relative humidity (RH), air temperature (T) and solar radiation (SR) observed synchronously from 1 September 2011 to 31 July 2014 in shifting sandy land in Cele in the margin of Taklimakan Desert were adopted in this paper. Time periods, duration of sand-driving wind and the correlations among average wind velocity,air temperature,RH and SR were analyzed through the research methods of regression analysis, statistical and correlated analysis. In order to provide theoretical basis for predicting sand and dust weather, interaction mechanisms of meteorological elements during sand and dust weather were discussed. The results show that the frequency of sand-driving wind more than 0.5 hour during the time period of 12:00(Beijing time, after the same) 13:00 is highest during a day and which is accounted for 8.78%,the frequency of sand and dust weather in the time period of 10:00 18:00 is accounted for 57.94% of the whole frequency. The frequency trend increases from morning and then decreases to night,and the changing trend is almost same with air temperature in daily change. The duration time from 2 hours to 2.5 hours of sand-driving wind is highest, which is accounted for 13.62%. The average monthly wind velocity is synchronously changing with average monthly air temperature during in shifting sandy land with significant linear correlation,while the changing trend for average monthly RH and average monthly air temperature is reverse. It shows significant correlations at the level of 0.01 between average wind velocity difference, temperature difference and RH between vertical distances, and it shows significant positive correlations at the level of 0.01 between average wind velocity and duration time of sand-driving wind. It shows significant negative correlation between average wind velocity, average wind velocity differnce in vertical distances and RH differences in vertical distances, and it shows significant negative correlations between average air temperature and average RH at the level of 0.01. It shows a significant negative correlation between average air temperature difference and average wind velocity difference in vertical distances,and the significant positive correlation is shown between average air temperature difference and average RH difference in vertical distances. Except for average wind velocity at the height of 0.5 m, the correlations are all significant between SR and rest meteorological parameters. The sand-driving winds in the seasons of spring and summer are dominant, the prevailing wind directions of sand-driving wind are mainly WNW and W wind directions in shifting sandy land in Cele, and the sand prevention measures should be strengthened in the orientation with W and WNW directions in oasis periphery.
