针对高耸建筑物风荷载分布特征的复杂性,在北京大学环境学院国家重点实验室2号环境风洞中,对缩尺比为1:300的英利大厦荷载模型进行了实验。用本文提出的试验数据处理方法对该试验结果进行分析、计算,得到了该建筑物的风振系数和体型系数,给出了建筑物表面最大和最小(吸力)风荷载值,为其结构抗风设计提供了依据,以确保该建筑物在100年重现期风速下的安全性和稳定性.

应用子波分析对在环境风洞中模拟的平坦及城市近地面边界层湍流进行了研究,探讨了湍流的间歇性结构与湍流的串级输送.实验结果表明,近地面边界层的湍流行为具有强烈的间歇性特征,因而在用数值或物理模拟近地面层湍流时这种间歇性时间尺度以及相应的几何尺度必须加以考虑.

Strawbridge KB, Li SM. Optical properties of aerosols obtained from airborne lidar and several in-situ instruments during RACE, in LIDAR ATMOSPHERIC MONITORING.Vol 3104.; 1997:204-211.Abstract
Two aircraft, the National Research Council of Canada (NRCC) Convair 580 (CV580) and NRCC DHC-6 Twin Otter, along with the Yarmouth and Digby Ferries, a ground site near Yarmouth and coordination with satellite overpasses (AVHRR and LANDSAT) provided an exceptionally well rounded compliment of observing platforms to meet the project objectives for the Radiation, Aerosols and Cloud Experiment (RACE) (refer to http://www.on.doe.ca/armp/RACE/ RACE.html for a complete list of instrumentation and investigators involved). The general flight plans involved upwind measurements of a selected target by the CV580 lidar, followed by coincident flights allowing the Twin Otter to perform in-site measurements while the Convair used a variety of remote sensors from above. The CV580 then descended to perform in-site measurements including size segregated samples through the use of a micro-orifice uniform deposit impactor (MOUDI). This paper will focus on the airborne lidar results during RACE and in particular introduce two case studies comparing the lidar with a MOUDI impactor and ASASP particle probe using Mie theory.
