利用2010年和2011年春季在新疆百里风区十三间房气象站观测取得的风廓线雷达资料，分析了该地区两次强风天气过程三维风随高度的分布特征。研究表明：（1）风廓线雷达对大风的总体观测结果是准确的，由于受地物杂波等因素影响，某些高度层探测结果不佳。（2）十三间房大风爆发迅速，低空风速强劲，最大风速可达40m／s以上，大风急流区位于2500m高度以下，急流区无明显的水平和垂直风切变。（3）2010年4月19—20日大风随高度无显著变化，为一致的北风气流；2011年3月12—13日大风过程，2000m以下为北风控制，2000～4000m高度风速风向变化复杂，存在风向随高度逆时针和顺时针的多次偏转，4000m以上为平直的西风气流。（4）大风过程中，大气在铅直方向既可做上升运动，也可做下沉运动。通过对速度谱宽的分析，谱宽时间一高度分布与大风随时间和高度的变化有较好的一致性。

To study the three-dimensional wind field characteristics of the gale weather at the Hundred Kilometres Gale Area in XinJiang, the Institute of Urumqi Desert Meteorology of China Meteorological Administration held a spring observation experiment from 2010 to 2011 on the Thirteen Houses in the Hundred Kilometres Gale Area. The study shows: (1) the mainly observational effect of wind profiler radar for gale was very good, although some height layer defection was not actualbecause the ground disorderly wave and other factors affect; (2) the gale at the Thirteen Houses area broke out rapidly, the wind speed was high the highest of which reached 40 rrds and the gale jet area was situated below 2500m altitude and there was not the horizontal and vertical wind shear ; (3) in the process of the gale of the Thirteen Houses, the wind did not change with the altitude. Moreover, the time-height distribution of spectrum width was correspond with the start and end time of the gale.
