A numerical model is at the core of every NWP product. It can be a model of the atmosphere that covers the entire globe and generates forecasts at any point. In this case, the best result is achieved by using statistical approaches and AI technologies to correct the output of the numerical models.
We use the regional atmospheric model WRF-ARW for the purpose of forecasting local weather features. Our specialists carefully select both, the optimal spatial resolution of the regional model and a set of physical parameterizations in order to make the computing resources cost-effective.
To improve the quality of the forecast based on a regional model, both approaches are applicable to global models, and more advanced techniques are used: methods of assimilation of observational data by the model itself and the use of an ensemble approach.
Ultimately, choosing a regional WRF-ARW mode as the core of the project offers more opportunities, since all stages of model tuning are under the control of our specialists. Nowcasting is based on the usage of radar data and methods of the extrapolation of these data. The prediction of the movement of the precipitation zone and/or thunderstorm cells can be obtained with a high-detailed temporal and spatial resolution. It is especially important for airports and regions with unsteady weather.
We are confident that our experience in numerical modeling and the provision of forecasting services can be useful in various fields of activity and economy, and the results in the form of weather forecasts can prevent or reduce damage and increase economic efficiency, which is confirmed by our existing forecasting projects.
