It has long been recognized that the exact timing, location and severity of local weather events are determined by what is termed by meteorologist as mesoscale processes. The Principal Investigator's overall objective is to study mesoscale phenomena embedded in larger cyclonic storms to advance knowledge of the structure and origin of such systems and to evaluate the prediction capabilities of present models. Specific phenomena to be investigated include frontal substructures, mesoscale gravity waves and small vortices in polar air masses. Research will be primarily accomplished through numerical modeling studies conducted in conjunction with scientists from the National Center for Atmospheric Research.

长期以来，人们一直认为，当地天气事件的确切时间、地点和严重程度由气象学家所称的中尺度过程决定。首席调查员的总体目标是研究较大气旋风暴中的中尺度现象，增进对这类系统的结构和起源的了解，并评估目前模式的预测能力。要研究的具体现象包括锋面子结构、中尺度重力波和极地气团中的小涡旋。研究将主要通过与国家大气研究中心的科学家一起进行的数值模拟研究来完成。
