Funded by a Research Initiation Award, experimental research will be carried out on microbursts. Microbursts are intense downdrafts which can occur during intense thunderstorms. Experimental information is lacking, and this research will create laboratory simulations with heavy saline water in a water tank experiment with otherwise freshwater. Flow visualization and particle imaging velocimetry will provide data on the dynamics of microbursts and their interaction with the ground. Microbursts have been responsible for the catastrophic crashes of aircraft, and their structure and development is still largely unknown.

在研究启动奖的资助下，将对微暴进行实验研究。微爆发是一种强烈的下沉气流，可能发生在强烈的雷暴期间。实验信息缺乏，这项研究将在水箱实验中创建重咸水和其他淡水的实验室模拟。流动显示和粒子成像测速技术将提供有关微爆发动力学及其与地面相互作用的数据。微爆发是导致飞机灾难性坠毁的原因，其结构和发展在很大程度上仍不清楚。
