1. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : 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.

2. Analysis of High and Low Rossby Wave Phase Speed Events Over Northern Mid-Latitudes
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : The large-scale, mid-latitude circulation in the upper troposphere is dominated by Rossby waves. The jet stream flows along the wave structure and surface cyclones can be found ahead of the troughs of the waves, propagating eastward. READ MORE

3. Large-Scale Atmospheric Drivers of Extreme Temperature Anomalies During Springtime in the Arctic
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : In this project warm extreme temperature events in the Arctic region during the spring months March, April and May were identified and analysed. In the analysis daily average NCEP reanalysis data from NOAA/OAR/ESRL PSL format was used. READ MORE

4. Modelling the Formation and Propagation of Orographic Rossby Waves
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : Orographic Rossby waves are the main mechanism by which the jet streams meander aroundthe Earth and have possibly far-reaching impacts on weather and climate (chapter 1). Hence,they are of particular importance to study and this project should serve as a starting point inwhat to consider when trying to model these waves. READ MORE
