Atmospheric dispersion calculations are made using the HYSPLIT Particle Dispersion Model for studying the transport and dispersion of air-borne releases from point elevated sources in the Mississippi Gulf coastal region. Simulations are performed separately with three meteorological data sets having different spatial and temporal resolution for a typical summer period in 1-3 June 2006 represent...

In this study, the general impact of high-resolution moving nesting domains on tropical cyclone (TC) intensity and track forecasts was verified, for a total 107 forecast cases 33 TCs, using Weather Research Forecasting (WRF) model. The experiment, with coarse resolution 12 km, could not significantly capture intensification process, especially maximum intensities (>60 m s−1). intense TCs wer...

To indicate the best airfoil profile for different sections of a blade, five airfoils; included S8xx, FFA and AH series was studied. Among the most popular wind power blades for this application were selected, in order to find the optimum performance. Nowadays, modern wind turbines are using blades with multi airfoils at different sections. SST-K-ω model with different wind speed at large scale...

Based on fractal models for the horizontal distribution of cloud density, Landsat-type (i.e., 30 m resolution) radiance fields were simulated within the Nonlocal Independent Pixel Approximation (NIPA), an improved version of the Independent Pixel Approximation (IPA) that uses only the local optical thickness, Scale-by-scale analyses of liquid water variability inside stratus clouds indicate sca...

In recent years, pyroclastic covers mantling slopes in the Campania region of southern Italy have frequently been affected by flowslides. Due to high exposure and demographic pressure in these areas, assessment of the potential effects of climate change on the frequency of such events has become a crucial issue. In this regard, our paper proposes a simulation chain comprising three main element...

a sensitivity analysis of the flood safety of solaimantangeh dam using a regional climate change simulation is presented. based on the output of the ccsm (community climate change system model) general circulation model, the nircm (north of iran regional climate model) computes regional scale output with 50 km spatial resolution and 21 vertical layers. using the sres (special report emission sc...

Urban expansion studies have focused on two-dimensional planar dimensions, ignoring the impact of building height growth changes in vertical direction urban three-dimensional (3D) spatial expansion. Past 3D simulation tended to focus simulating virtual cities, and a few attempted build models achieve synergistic real cities. This study proposes an model horizontal growth. The future land use wa...
