摘　　要：利用2007年夏末(8月21日～9月11日)在山东石岛湾地区进行的3测站联合低空探测资料,分析各站逐时次的热内边界层高度。结合近地面流动和反向轨迹分析方法判断单次探测资料代表的上风风程(fetch),以估算空气从海面进入陆地后到达观测点的行进距离。统计3个测站的资料获得当地热内边界层随深入陆地距离的变化,并归纳出经验关系。结果表明,当地热内边界层高度偏大,但变化趋势基本符合距离的1/2次方律,与前人的理论和实验结果一致。Radiosonde data of three stations was analyzed for the thermal internal boundary layer （TIBL） height above Shidaowan nuclear power station site area. The data covers the period of 21 August to 11 September, 2007. Wind fields were diagnosed for backward trajectory analysis, which was in turn used for determining the upwind land surface fetch of an individual sounding, i.e., the distance from the location of the radiosonde station to the coast line along the backward trajectory. Empirical relationship was derived between the TIBL height and the distance of upwind fetch. Results showed that TIBL height observed the 1/2 power law with the distance of upwind fetch, agreed with previous theoretical and experimental results, although the values of the TIBL in this area were relatively higher.
