Employment of MM5 in simulating MCSs developed in and around Bangladesh

open access: hybridMAUSAM, 2009
The Mesoscale Convective Systems (MCSs) produce numerous weather hazards with their variety of forms. The formation mechanism of MCSs is thus important to know for Bangladesh and its surroundings, because this region is one of the heaviest rainfall areas in the tropical zone.

MM5 simulations of a SCOS97-NARSTO episode [PDF]

open access: yesAtmospheric Environment, 2003
Abstract MM5 simulations of the 4–7 August SCOS97-NARSTO ozone episode in the SoCAB showed that a relatively rare easterly upper-level background flow influenced surface wind flow directions at in-land sites. An inland-moving surface convergence zone resulted where the offshore background flow met an inland moving westerly (sea breeze plus thermal ...

2-way coupling the hydrological land surface model PROMET with the regional climate model MM5 [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Most land surface hydrological models (LSHMs) consider land surface processes (e.g. soil–plant–atmosphere interactions, lateral water flows, snow and ice) in a spatially detailed manner.

Comparison of Urban Canopy Schemes and Surface Layer Schemes in the Simulation of a Heatwave in the Xiongan New Area

open access: yesAtmosphere, 2022
Due to rapid growth and expansion, Xiongan New Area is at risk for heatwaves in the present and future induced by the urban heat island effect. Based on eight combined schemes, including two common WRF surface layer schemes (MM5 and Eta) and urban canopy

Sensitivity of the Community Multiscale Air Quality (CMAQ) model v4.7 results for the eastern United States to MM5 and WRF meteorological drivers [PDF]

open access: yesGeoscientific Model Development, 2010
This paper presents a comparison of the operational performances of two Community Multiscale Air Quality (CMAQ) model v4.7 simulations that utilize input data from the 5th-generation Mesoscale Model (MM5) and the Weather Research and Forecasting (WRF ...

Determination of Upwind and Downwind Areas of Seoul, Korea Using Trajectory Analysis

open access: yesAsian Journal of Atmospheric Environment, 2010
To identify the domains that have the greatest impacts on air quality at the surface, both the upwind and downwind areas of Seoul were determined by season using refined wind fields. Four consecutive days were selected as the study period typical of each

Estimation of the systematic error of precipitation and humidity in the MM5 model [PDF]

open access: yesAdvances in Geosciences, 2008
Abstract. To comprehensively diagnose model capabilities in simulating atmospheric flow including the relevant microphysical processes, the main prognostic fields of the MM5 model are compared with ERA40 reanalysis data. This approach allows to identify and compare meaningful features of model parameterization schemes and to quantify model errors ...
