(Boston, Massachusetts : American Meteorological Society, 2018)
    Forecast errors with respect to wind, temperature, moisture, clouds, and precipitation largely correspond to the limited capability of current Earth system models to capture and simulate land–atmosphere feedback. To ...
  • Franzmann, Michael (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Geochemical behavior and transport mechanisms of anthropogenic radionuclides in natural systems are of major importance to evaluate their distribution at contaminated areas and storage sites and for reliable estimation and ...
  • Gryanik, V.M.; Hartmann, J.; Raasch, S.; Schröter, M. (Boston, Massachusetts : American Meteorological Society, 2005)
    The Millionshchikov hypothesis of quasi-normal distribution of fourth-order moments fails for convective conditions where the probability density functions of temperature and vertical velocity fluctuations are skewed. This ...
  • Tafferner, A.; Hauf, T.; Leifeld, C.; Hafner, T.; Leykauf, H.; Voigt, U. (Boston, Massachusetts : American Meteorological Society, 2003)
    This paper describes the design of the Advanced Diagnosis and Warning System for Aircraft Icing Environments (ADWICE) and presents results for two different icing weather situations with typical icing conditions. ADWICE ...
  • Hofmann, Martin (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    The electricity generation from photovoltaic systems (PV) is becoming more relevant from year to year in the context of global power generation, with the newly installed capacity exceeding all other forms of generation for ...
  • Schröter, M.; Raasch, S.; Jansen, H. (Boston, Massachusetts : American Meteorological Society, 2005)
    Large-eddy simulations (LES) have been carried out in order to investigate the structure and development of organized mesoscale cellular convection (MCC) during cold air outbreaks (CAOB) and to reevaluate results by Müller ...

  • Mengelkamp, H.-T.; Beyrich, F.; Heinemann, G.; Ament, F.; Bange, J.; Berger, F.; Bösenberg, J.; Foken, T.; Hennemuth, B.; Heret, C.; Huneke, C.; Johnsen, K.-P.; Kerschgens, M.; Kohsiek, W.; Leps, J.-P.; Liebethal, C.; Lohse, H.; Mauder, M.; Meijninger, W.; Raasch, S.; Simmer, C.; Spieß, T. A.; Tittebrand, A.; Uhlenbrock, J.; Zittel, P. (Boston, Massachusetts : American Meteorological Society, 2006)
    The representation of subgrid-scale surface heterogeneities in numerical weather and climate models has been a challenging problem for more than a decade. The Evaporation at Grid and Pixel Scale (EVA-GRIPS) project adds ...
  • Noh, Y.; Goh, G.; Raasch, S. (Boston, Massachusetts : American Meteorological Society, 2010)
    Analysis of large-eddy simulation data of the ocean mixed layer under convection reveals that the contribution from wind stress decreases with time as a result of inertial oscillation in the extratropical ocean and that ...
  • Noh, Y.; Goh, G.; Raasch, S.; Gryschka, M. (Boston, Massachusetts : American Meteorological Society, 2009)
    The formation of a diurnal thermocline in the ocean mixed layer under a stabilizing buoyancy flux was simulated successfully by large-eddy simulation, reproducing various features consistent with observation. The analysis ...
  • Noh, Y.; Goh, G.; Raasch, S. (Boston, Massachusetts : American Meteorological Society, 2011)
    Analysis of large eddy simulation data reveals that Langmuir circulation (LC) induces a significant enhancement of the mixed layer deepening, only if the mixed layer depth (MLD) h is shallow and the buoyancy jump across ...

  • Noh, Y.; Kang, I.S.; Herold, M.; Raasch, S. (College Park, MD : American Institute of Physics, 2006)
    The settling process of suspended particles in the turbulent flow was investigated by analyzing the Lagrangian motion of a large number of particles in the ocean mixed layer simulated by large eddy simulation (LES), focusing ...
  • Noh, Y.; Min, H.S.; Raasch, Siegfried (Boston, Massachusetts : American Meteorological Society, 2004)
    Large eddy simulation (LES) of the ocean mixed layer was performed in which both wave breaking and Langmuir circulation are realized. Wave breaking was represented by random forcing consistent with the observed near-surface ...
  • Letzel, M.O.; Raasch, S. (Boston, Massachusetts : American Meteorological Society, 2003)
    Mesoscale circulations induced by differential boundary layer heating due to surface inhomogeneities on scales of 5 km and more can significantly change the average properties and the structure of the convective boundary ...
