1. 1. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Michael Konrad Schutte; [2023]
   Keywords : jet stream; Rossby waves; polar vortex; spectral analysis; dynamic systems theory; sudden stratospheric warmings; strong polar vortex events; jetström; Rossbyvågor; polär virvel; spektralanalys; dynamisk systemteori; plötsliga stratosfäriska uppvärmingar; starka polvortexhändelser;

   Abstract : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.
