Numerical errors above steep topography: A model intercomparison
Meteorologische Zeitschrift, 2004 This paper compares the behaviour of three mesoscale models (MM5, Penn State University/NCAR, LM, German Weather Service, and KAMM2, IMK Karlsruhe) in the vicinity of a steep isolated mountain under zero-wind conditions.

MM5 v3.6.1 and WRF v3.5.1 model comparison of standard and surface energy variables in the development of the planetary boundary layer [PDF]
Geoscientific Model Development, 2014 Air quality forecasting requires atmospheric weather models to generate accurate meteorological conditions, one of which is the development of the planetary boundary layer (PBL).

The role of atmospheric boundary layer-surface interactions on the development of coastal fronts [PDF]
Annales Geophysicae, 2007 Frictional convergence and thermal difference between land and sea surface are the two surface conditions that govern the intensity and evolution of a coastal front.

Evaluating the performance of two surface layer schemes for the momentum and heat exchange processes during severe haze pollution in Jing-Jin-Ji in eastern China [PDF]
Atmospheric Chemistry and Physics, 2018 The turbulent flux parameterization schemes in the surface layer are crucial for air pollution modeling. There have been some deficiencies in the prediction of air pollutants by atmosphere chemical models, which is closely related to the uncertainties of

The initial conditions of star formation in the Ophiuchus main cloud: Kinematics of the protocluster condensations [PDF]
, 2007 The earliest phases of clustered star formation and the origin of the stellar initial mass function (IMF) are currently much debated. In order to constrain the origin of the IMF, we investigated the internal and relative motions of starless condensations

Mesoscale modeling of lake effect snow over Lake Erie – sensitivity to convection, microphysics and the water temperature [PDF]
Advances in Science and Research, 2010 Lake effect snow is a shallow convection phenomenon during cold air advection over a relatively warm lake. A severe case of lake effect snow over Lake Erie on 24 December 2001 was studied with the MM5 and WRF mesoscale models.

Regional modeling of atmospheric mercury: impact of meteorological variables
E3S Web of Conferences, 2013 The atmospheric mercury concentration in Europe was simulated with the regional atmospheric chemistry transport model CMAQ-Hg. Two sets of meteorological fields, one from MM5 and one from COSMO-CLM (CCLM) were used to drive the model.
