1. 1. Analysis of High and Low Rossby Wave Phase Speed Events Over Northern Mid-Latitudes

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Emma Rosengren; [2022]
   Nyckelord :Rossby waves; phase speed; atmospheric blocking; storm track; windstorms; Rossbyvågor; fashastighet; atmosfärisk blockering; lågtrycksbana; vindstormar;

   Sammanfattning : 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. LÄS MER

   Sammanfattning : This study aims to investigate the possible historical correlation between sea ice reduction in the Arctic and cold winters in Central Europe. The study is conducted over a cold period in Europe known as the Little Ice Age (LIA), 1400–1850, and uses a Global Climate Model with eight different forcing scenarios. LÄS MER
