Winds near the ground on Titan for Dragonfly landing site (near Selk crater, 10°N) mid-2030s (Titan late southern summer, Ls ~ 310°) are estimated mission design purposes. Prevailing winds due to global circulation typically 0.5 m/s, and do not exceed 1 m/s. Local terrain-induced flows such as slope appear be similarly capped at At various sites times, these two contributions will vectorially c...

The Modeling Eddies in the Southern Ocean (MESO) project uses numerical sensitivity studies to examine the role played by Southern Ocean winds and eddies in determining the density structure of the global ocean and the magnitude and structure of the global overturning circulation. A hemispheric isopycnal-coordinate ocean model (which avoids numerical diapycnal diffusion) with realistic geometry...

Current velocity in aquatic environments has major implications for the diversity, abundance and ecology of aquatic organisms, but quantifying these currents has proven difficult. This study utilises a simple and inexpensive instrument (<$150) to provide a detailed current velocity profile of the coral-reef system around Lizard Island (Great Barrier Reef, Australia) at a spatial and temporal sc...

Tornadoes are violently rotating columns of air extending from thunder storms to the ground. While extensive studies have been conducted to assess wind loads and flow structures around building models in strong winds, most of the previous investigations were conducted with straight-line winds. Bienkiewicz and Dudhia (1993) found that the wind loads acting on building models in tornado-like wind...

We present a semi–analytic treatment of galactic winds within high resolution, large scale cosmological N–body simulations of a ΛCDM Universe. The evolution of winds is investigated by following the expansion of supernova driven supershells around the several hundred thousand galaxies that form in an approximately spherical region of space with diameter 52h−1 Mpc and mean density close to the m...

Odour emission from landfill areas has a high potential to cause significant annoyance to people living in their surroundings. In order to avoid odour nuisance, it is crucial to select the best location in the project phase of these facilities. In the present work, two approaches of the Gaussian atmospheric dispersion model were employed to predict odour impact from a projected landfill area an...
