RISThe Impact of the Temperature Inversion Breakup on the Exchange of Heat and Mass in an Idealized Valley: Sensitivity to the Radiative Forcing
Publisher: American Meteorological Society
Abstract: he breakup of a nocturnal temperature inversion during daytime is studied in an idealized valley by means of high-resolution numerical simulations. Vertical fluxes of heat and mass are strongly reduced as long as an inversion ...
Validation of an Urban Surface Exchange Parameterization for Mesoscale Models—1D Case in a Street Canyon
Publisher: American Meteorological Society
Abstract: A detailed urban parameterization scheme is used in and above a street canyon. To validate this new scheme, the model is run offline on a vertical column (one-dimensional simulations), using measurements from a 30-m-high ...
Assessing the Benefits of Convection-Permitting Models by Neighborhood Verification: Examples from MAP D-PHASE
Publisher: American Meteorological Society
Abstract: High-resolution numerical weather prediction (NWP) models produce more detailed precipitation structures but the real benefit is probably the more realistic statistics gained with the higher resolution and not the information ...
The Impact of Horizontal Model Grid Resolution on the Boundary Layer Structure over an Idealized Valley
Publisher: American Meteorological Society
Abstract: he role of horizontal model grid resolution on the development of the daytime boundary layer over mountainous terrain is studied. A simple idealized valley topography with a cross-valley width of 20 km, a valley depth of ...
Modification of an Operational Dispersion Model for Urban Applications
Publisher: American Meteorological Society
Abstract: An operational multisource, multireceptor Gaussian dispersion model, the Danish regulatory model Operationelle Meteorologiske Luftkvalitetsmodeller (OML) has been modified for applications in urban environments. A so-called ...
High-Resolution Large-Eddy Simulations of Flow in a Steep Alpine Valley. Part II: Flow Structure and Heat Budgets
Publisher: American Meteorological Society
Abstract: This paper analyzes the three-dimensional flow structure and the heat budget in a typical medium-sized and steep Alpine valley?the Riviera Valley in southern Switzerland. Aircraft measurements from the Mesoscale Alpine ...
Monthly Weather Forecasts in a Pest Forecasting Context: Downscaling, Recalibration, and Skill Improvement
Publisher: American Meteorological Society
Abstract: onthly weather forecasts (MOFCs) were shown to have skill in extratropical continental regions for lead times up to 3 weeks, in particular for temperature and if weekly averaged. This skill could be exploited in practical ...
The World is Not Flat: Implications for the Global Carbon Balance
Publisher: American Meteorological Society
Abstract: processes contributing to the global CO2 budget, net uptake by the land surface bears the largest uncertainty. Therefore, the land sink is often estimated as the residual from the other terms that are known with greater ...
Reasons for the Extremely High-Ranging Planetary Boundary Layer over the Western Tibetan Plateau in Winter
Publisher: American Meteorological Society
Abstract: he planetary boundary layer (PBL) over the Tibetan Plateau (with a mean elevation about 4 km above sea level) reaches an unmatched height of 9515 m above sea level. The proximity of this height to the tropopause facilitates ...
