摘要

利用2012年7月“巴丹吉林沙漠陆-气相互作用及其对区域气候的影响研究”实验所得到的观测资料和中尺度气象模式WRF，对夏季巴丹吉林沙漠对流边界层高度发展的特征及其影响因素进行了研究。结果表明：（1）2012年7月在巴丹吉林沙漠连续观测到厚度超过3500 m的深厚对流边界层，其最大高度可达4000 m以上；当这种深厚对流边界层出现之前，当地中低层大气（1000～4000 m）存在近中性的残余层，而在没有近中性残留层出现时，即便地表感热通量较大，当天最大对流边界层高度却明显偏低；（2）WRF模式模拟结果表明残余层稳定度和对流边界层高度之间的负相关关系在空间区域成立，残余层位温直减率与当地对流边界层高度在时间和空间分布上都呈现显著的负相关关系；残余层位温直减率与对流边界层高度的空间相关系数最大值可达-0.51；（3）观测和模拟结果均表明残余层稳定度会直接影响由感热通量产生的对流边界层的发展效率，进而影响对流边界层的最大高度。通过研究发现，除感热通量外，近中性的残余层是巴丹吉林地区深厚对流边界层出现的关键条件之一。

Abstract

The characteristics and influencing factors of convective boundary layer height development of the Badain Jaran Desert were analyzed based on the observation data of July 2012 and WRF model. The result shows that: (1) Over the Badain Jaran desert, a convective boundary layer (CBL) that deeper than 4000 m has been observed on July 2012. It is also found that there was a nearly neutral residual layer in the morning before a deep CBL which was approximate 4000 m can be formed in the afternoon. When there was no residual layer in the morning as in 7 July, although the surface sensible heat flux was still intensive, the maximum depth of CBL on that day was only 1900 m. (2) The simulated maximum depth of CBL in different day varies much even the surface sensible heat flux changes little. After comparing the spatial distribution and temporal variation, it is found that the lapse rate within the residual layer owns not only a stronger time correlation but also a more significant pattern correlation with the CBL depth than the surface sensible heat flux. The maximum spatial correlation coefficient between the lapse rate within the residual layer and CBL height is -0.51. (3) Observations and simulated results show that the stratification status in the residual layer can directly affect the CBL development efficiency which is forced by sensible hear flux, and then affect the maximum CBL depth. Therefore, this study suggests that in addition to the sensible heat flux, the stratification status in the residual layer also plays an essential role for the development of CBL in the Badain Jaran desert in summer.
