Seasonal, Intraseasonal and Interannual Variability of Geopotential Heights in the Northern Hemisphere

在这项“研究机会奖”计划下，彭兰德博士将应用主振荡模式（POP）分析方法，分析北半球的高空数据，以描绘主要的大气遥相关模式。分析不仅可以找到空间结构，还可以确定这些结构是驻波还是行波，或者只是指数衰减结构。这个项目将提供有用的资料，用以计算驱动力的地理和时间特性。因此，这项工作可以提高我们模拟重要的季节内大气过程的能力。

Under this "Research Opportunities Award" project, Dr. Penland will apply a Principal Oscillation Pattern (POP) analysis method to upper air data from the Northern Hemisphere in order to delineate major atmospheric teleconnection patterns. The analysis would not only find spatial structures but also determine whether these are standing or travelling waves, or simply exponentially decaying structures. This project would provide useful information from which the geographical and temporal properties of driving forces can be calculated. Thus, this work may enhance our capability to model important intraseasonal atmospheric processes.
