abstract: numerical weather forecasting models are used for forecasting and dynamic conditions analysis of atmosphere phenomena in recent years. this research investigates dynamic and thermodynamic conditions in heavier precipitation events in different synoptic patterns in the southern coasts of caspian sea using wrf model. database precipitation events were formed. super heavy and heavy preci...

Visualizing extremely large and time-variant data presents a challenge in overcoming slow disk and network access. The Weather Research and Forecasting (WRF) model, used to model mesoscale weather phenomena, generates large amounts of storm system information that is visualized to better understand storm formation. WRF faces these caveats in disk and network bandwidth limitations. Using the ope...

This paper describes the coupling between a mesoscale numerical weather prediction model, the Weather Research and Forecasting (WRF) model, and a Lagrangian Particle Dispersion Model, the Stochastic Time-Inverted Lagrangian Transport (STILT) model. The primary motivation for developing this coupled model has been to reduce transport errors in continental-scale top– down estimates of terrestrial...

The thunderstorms are typical mesoscale systems dominated by intense convection. Mesoscale models are essential for the accurate prediction of such high-impact weather events. In the present study, an attempt has been made to compare the simulated results of three thunderstorm events using NMM and ARW model core of WRF system and validated the model results with observations. Both models perfor...

Abstract. High-mercury wet deposition in the southeastern United States has been noticed for many years. Previous studies came up with a theory that it was associated high-altitude divalent mercury scavenged by convective precipitation. Given coarse resolution of previous models (e.g., GEOS-Chem), this is still not fully tested. Here we employed newly developed WRF-GEOS-Chem (WRF-GC; WRF: Weath...

In this work we present the first results of an experiment to measure and model atmospheric delays by means of GPS, Synthetic Aperture Radar Interferometry (InSAR) and the Weather Research and Forecasting (WRF) model. The aim of the experiment is to device strategies to mitigate atmospheric phase delay artefacts in SAR interferograms.
