WRF SENSIBILITY TO MICROPHYSICS AND PLANETARY BOUNDARY LAYER AT MICRO-CATCHMENT SCALE: THE CASE OF THE QUINUAS CATCHMENT IN THE TROPICAL ANDES OF ECUADOR

Sensitivity of WRF Rainfall Simulations to Physical Parameterization Schemes over Tropical Peatlands in the Maritime Continent

Assessment of the sensitivity of the RegCM5 model to physical parameterization schemes in precipitation simulation in the Bandama watershed (Côte d’Ivoire)

This study evaluates how the choice of physical parameterization schemes affects precipitation simulation over the Bandama watershed (Côte d’Ivoire) using the fifth-generation Regional Climate Model (RegCM5). Sixteen configurations were built by combining four convection schemes (Emanuel, Kain–Fritsch, Grell, and Tiedt...

Hydrologic modeling in mountainous terrains with monsoonal climate: Do gridded precipitation data improve streamflow simulations?

Accurate hydrologic modeling in data-scarce mountainous regions remains challenging due to strong climatic variability, complex topography, and limited ground data. This study evaluates the influence of four precipitation inputs on the performance of the Soil and Water Assessment Tool Plus (SWAT+) model in the monsoo...

Evaluation of a Cumulus Scheme in the FV3-LAM and of Experimental MPAS Forecasts for the Summer 2025 Flash Flood and Intense Rainfall Experiment

A convection-allowing model (CAM) ensemble was run during the NOAA Hydrometeorological Testbed’s 2025 Flash Flood and Intense Rainfall Experiment. One of the goals was to evaluate the role and effects of a cumulus scheme on precipitation forecasting in CAMs, where four members of the ensemble have a scale-aware simpl...

Rapid intensification of Arabian Sea cyclonic storm and numerical simulation of ESCS Tauktae using the high-resolution ARW model

This study highlights the climatology of rapid intensification (RI) and rapid dissipation (RD) locations during 1990–2022 and suggests that RI and RD locations over the Arabian Sea (AS) have increased during 2012–2022. The results show that several RI locations occur within or near the 300-km offshore zone, highlightin...

Coupling WRF with HEC-HMS for streamflow forecasting in typical mountainous catchments of northwestern Iran

Nowadays, with the increase in the frequency of extreme rainfall events, the alerts provided by real-time flood forecasting systems are becoming essential to provide accurate and timely information for emergency response. This study uses the Weather Research and Forecasting (WRF) model and the Hydrologic Engineering Ce...
