1. Boundary Layer Studies above lake Erken using Modelling and UAV
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Internal boundary layers (IBLs) above lakes, created primarily by the autumn differential of land and lake surface temperatures, present a unique way of studying the lake-atmosphere coupling within the boundary layer. The small and mobile unmanned aerial vehicles (UAVs) contribute to new research areas within the boundary layer, offering high spatial resolution measurements to complement already existing observations.

2. Quasi-Biennial Oscillation och dess påverkan på klimatet i troposfären
Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : The Quasi-Biennial Oscillation (QBO) is the strongest phenomena influencing the stratopheric (~15-50 km height) circulation over the equator. QBO has two phases of downward propagating easterly and westerly winds, which has a total period of approximately 28 months and the phase is defined by the wind direction between the airpressure 25-50 hPa, which is roughly at a height of 30 km.
