3-D modeling of noctilucent cloud evolution and relationship to the ambient atmosphere Kiliani, Johannes , 1981- Text theses Text Hochschulschrift 2014 2014 eng electronic resourceremoteComputermedienOnline-Ressourcetext/htmlapplication/pdfOnline-Ressource Ill., graph. Darst. Noctilucent clouds (NLC) at the polar summer mesosphere are highly sensitive to atmospheric conditions, therefore they are an important climate indicator. In this thesis, an ice particle model is combined with circulation models to simulate the formation of NLC throughout the particle life cycle: Only 1% of ice particles grow to visible size (50 nm). The main part of particle growth takes place at 83 km altitude, within 6 hours prior to observation and is accompanied by upwelling. By using cylindrical particle shape, the simulated optical signal is made consistent with measurements. von Johannes Kiliani Rostock, Univ., Diss., 2014 551.567 550 UT 5250 38.81 http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2015-0028-8 http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2015-0028-8&pdf http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2015-0028-8 3-D modeling of noctilucent cloud evolution and relationship to the ambient atmosphere--(DE-627)812861019 urn:nbn:de:gbv:28-diss2015-0028-8 oclc: 935808480 ppn: (DE-627)817983767
