A Parameterization of Slantwise Convection in the WRF Model

Journal of the Atmospheric Sciences, 2022
Abstract In this study, we introduce a parameterization scheme for slantwise convection (SC) to be considered for models that are too coarse to resolve slantwise convection explicitly (with a horizontal grid spacing coarser than 15 km or less). This SC scheme operates in a locally defined 2D cross section perpendicular to the deep-layer-averaged ...

Fetch imaged by SAR and simulated by WRF model

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
In this paper, we present the synthetic aperture radar (SAR) observation of the detailed sea surface wind patterns associated with fetch in the Bohai Sea, China. We then implemented the WRF model to simulate the entire processes of this weather event. WRF model results show the dynamics and evolution of this event.

Sensitivity of the WRF Model to the Parameterized Physical Process

2020
The present study explores the performance of different microphysics (MP) and cumulus parameterization (CP) scheme in the simulation of an extreme rainfall event during 0000 UTC July 11 2016 - 0000 UTC July 12, 2016 at the west coast of India, Mumbai.

PM Modelling over Nepal with WRF-Chem

2016
Very high particulate matter (PM) and black carbon (BC) concentrations are observed in the Kathmandu Valley, Nepal. With an aim of gaining a better understanding of the dynamics of these air pollutants, PM and BC simulations with the WRF-Chem model have been performed.

Explicit Numerical Diffusion in the WRF Model

Monthly Weather Review, 2007
AbstractDiffusion that is implicit in the odd-ordered advection schemes in early versions of the Advanced Research core of the Weather Research and Forecasting (WRF) model is sometimes insufficient to remove noise from kinematical fields. The problem is worst when grid-relative wind speeds are low and when stratification is nearly neutral or unstable ...

Comparison of the performances between the WRF and WRF-LES models in radiation fog – A case study

Atmospheric Research, 2019
Abstract It is desirable to find a numerical forecast model that can better simulate and forecast the evolution of radiation fog. Here, observations made on 21 December 2015 at Nanjing University of Information Science and Technology (NUIST) are used to validate simulations from the Weather Research and Forecast (WRF) model and WRF nested Large-Eddy ...

Simulations of energy and water balances with WRF and WRF-Hydro models: the role of model coupling and parameterizations

We tested the widely used atmospheric WRF (Weather Research and Forecasting) model in a coupled mode to the hydrological model WRF-Hydro. The coupled WRF/WRF-Hydro model adds the simulation of horizontal surface and subsurface flow of water relative to the standalone WRF.

Extension of capabilities of WRF mesoscale model in DUCT

2023
Evalution of the urban heat is an essential aspect of providing suitable outdoor thermal comfort to urban dwelers. In this sense, urban climate modeling becomes a necessary tool to understand the interaction between different heat sources and the urban atmosphere. One of these models is the Weather Research and Forecasting model (WRF).

Temperature Seasonal Predictability of the WRF Model

2016
It is a common sense that there is no usable forecast skill at seasonal lead times due to the rapid drop-off of the predictability after a few days from the initialization of a simulation. However, there is some skill in predicting anomalies in the seasonal average of the weather such as anomalies of the persistent atmospheric patterns or even ...

The application of WRF model in the wave numerical forecast

Proceedings of 2012 2nd International Conference on Computer Science and Network Technology, 2012
By combining the new generation of weather research and prediction model (WRF) and the third generation wave model (WAVEWATCHIII), it established an Atmospheric-Wave numerical forecast system. Adopting the forecasting wind from WRF model as forcing term of wave model, a nested wave model is built from the Western Pacific to coastal areas of China.
