Three related investigations are to be conducted in the area of environmental fluid mechanics, in particular density stratified turbulent flow. The approach is essentially experimental. The three topics are: mixing between turbulent layers of different properties separated by a laminar region, the horizontal outflow generated near the ground by heavy descending air masses, and mixing and internal wave generation in a variable properties stably stratified turbulent shear flow. The research is relevant to oceanic mixing, pollutant transport in the atmosphere, and wind shear due to microbursts.

在环境流体力学领域，特别是密度分层湍流领域，将进行三个相关的研究。这种方法基本上是试验性的。这三个主题是：被层流区隔开的不同性质的湍流层之间的混合，沉重的下降气团在地面附近产生的水平外流，以及变性质稳定分层湍流剪切流中的混合和内波产生。这项研究与海洋混合、污染物在大气中的传输以及微爆发引起的风切变有关。
