The role of planetary waves in coupling processes of the middle atmosphere Wendt, Vivien , 1984- Text theses Text Hochschulschrift 2014 2014 eng electronic resourceremoteComputermedienOnline-Ressourcetext/htmlapplication/pdfOnline-Ressource Ill., graph. Darst. The middle atmosphere is disturbed by planetary waves (PWs) especially in the northern hemispheric winter. The interaction of PWs with the mean flow causes Sudden Stratospheric Warmings (SSWs), the most impressive vertical coupling process of the middle atmosphere. While the stratospheric temperature increases of up to 80K within a few days it decreases in the mesosphere of up to 30K. In this thesis the average behavior of SSWS as well as unusually southward extended SSWs are studied using high-resolution local radar measurements, global satellite observations and assimilated model data. von Vivien Matthias Rostock, Univ., Diss., 2014 551.55 550 UT 5250 38.81 http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2014-0103-8 http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2014-0103-8&pdf http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2014-0103-8 The role of planetary waves in coupling processes of the middle atmosphere--(DE-627)786357509 urn:nbn:de:gbv:28-diss2014-0103-8 oclc: 935558308 ppn: (DE-627)793016029
