The South American Biomass Burning Analysis (SAMBBA) field campaign took detailed in situ flight measurements of aerosol during the 2012 dry season to characterise biomass burning aerosol and improve understanding of its impacts on weather and climate. Developments have been made to the Weather Research and Forecast model with chemistry (WRF-Chem) model to improve the representation of biomass ...
An offline-coupled model (WRF/Polyphemus) and an online-coupled model (WRF/Chem-MADRID) are applied to simulate air quality in July 2001 at horizontal grid resolutions of 0.5 and 0.125 over Western Europe. The model performance is evaluated against available surface and satellite observations. The two models simulate different concentrations in terms of domainwide performance statistics, spatia...
A fully coupled ‘‘online’’ Weather Research and Forecasting/Chemistry (WRF/Chem) model has been developed. The air quality component of the model is fully consistent with the meteorological component; both components use the same transport scheme (mass and scalar preserving), the same grid (horizontal and vertical components), and the same physics schemes for subgrid-scale transport. The compon...

طوفان گرد و غبار پدیده ای مهم و تاثیرگذار می باشد و دارای خسارات زیادی است و همینطور منطقه یزد نیز مستعد ایجاد طوفان است، به همین خاطر به دنبال راهکاری مناسب برای کاهاش خسارات هستیم. یک روش مناسب برای کاهش خسارات پیش بینی این پدیده و روشی مناسب برای پیش بینی نیز استفاده از مدل های دینامیکی مانند wrf است. در این پژوهش ما از مدل جفت شده wrf-chem برای پیش بینی این پدیده بهره گرفتیم و سعی کردیم تا ...
A suite of physical parameterizations (deep and shallow convection, turbulent boundary layer, aerosols, cloud microphysics, and cloud fraction) from the global climate model Community Atmosphere Model version 5.1 (CAM5) has been implemented in the regional model Weather Research and Forecasting with chemistry (WRF-Chem). A downscaling modeling framework with consistent physics has also been est...

[1] In previous studies, the Yonsei University (YSU) planetary boundary layer (PBL) scheme implemented in the Weather Research and Forecasting (WRF) model was reported to perform less well at night, while performing better during the day. Compared to observations, predicted nocturnal low-level jets (LLJs) were typically weaker and higher. Also, the WRF model with Chemistry (WRF/Chem) with the Y...
