Dr. Dunkerton will conduct a series of investigations designed to improve understanding of the structure of the tropical troposphere and lower stratosphere, including its intraseasonal and interannual variations, effects of tropical phenomena on the extratropical atmosphere and vice versa, coupling between the troposphere and stratosphere, and stratosphere-troposphere exchange. The research will consist of both observational analyses and theoretical modeling. Particular emphasis will be given to the studies of the effect of gravity-wave variation on the stratospheric quasi- biennial oscillation (QBO), the evolution of the tropopause temperature and dynamical processes responsible for its variation, and the effect of baroclinic waves on the Hadley circulation. ***

Dunkerton博士将进行一系列调查，旨在提高对热带对流层和平流层下部结构的理解，包括其季节内和年际变化，热带现象对热带大气层外大气的影响，反之亦然，对流层和平流层之间的耦合，以及平流层对流层交换。 该研究将包括观察分析和理论建模。 重点研究重力波变化对平流层准两年振荡（QBO）的影响、对流层顶温度的演变及其变化的动力过程、斜压波对Hadley环流的影响。 ***
