Seminar Room MCZ, 440
Speaker: Wanying Kang
Wanying will be presenting the paper “Seasonal Variability of the Polar Stratospheric Vortex in an Idealized AGCM with Varying Tropospheric Wave Forcing.”
Here are her thoughts on the paper:
Using an idealized atmospheric model with seasonal cycle, they investigated how the polar stratosphere seasonal variability responds to varying topography. Specifically, they focused on the response in Sudden Stratospheric Warming (SSW) frequency, and the timing of final warmings. K=2 topography is more efficient than k=1 in shifting final warming and changing SSW frequency. The response saturated at modest topography height. In the discussion, I will also give a brief background introduction.
