The viscosity equation further presupposes that there is only one type of gas molecules, and that the gas molecules are perfect elastic and hard core particles of spherical shape. This assumption of elastic, hard core spherical molecules, like billiard balls, implies that the collision cross section of one molecule can be estimated by σ = π ...
It simulates release and toxic/flammables pollutants dispersion in various weather conditions in calculated 3D complex winds and turbulence fields. Gas, particles, droplets induced flow and transport/diffusion is simulated with Navier-Stokes equations for jet-like, dense, cold, cryogenic or hot, buoyant releases.
Atmospheric thermodynamics is the study of heat-to-work transformations (and their reverse) that take place in the Earth's atmosphere and manifest as weather or climate. . Atmospheric thermodynamics use the laws of classical thermodynamics, to describe and explain such phenomena as the properties of moist air, the formation of clouds, atmospheric convection, boundary layer meteorology, and ...
East Los Angeles, the Gateway Cities, and parts of the San Gabriel Valley average the warmest winter high temps (72 °F, 22 °C) in all of the western U.S., and Santa Monica averages the warmest winter lows (52 °F, 11 °C) in all of the western U.S. Palm Springs, a city in the Coachella Valley, averages high/low/mean temperatures of 75 °F/50 ...
As the white stuff fell, excited locals took to social media to share their photos and videos of the unusual occasion.
Winter storm warnings were in effect from Texas through the Carolinas, according to the National Weather Service. As of 8 p.m. ET, more than 2,200 U.S. flights had been canceled , according to ...
An unusually cold weather system from the Gulf of Alaska interrupted summer along the West Coast on Saturday, bringing snow to mountains in California and the Pacific Northwest and prompting the ...
One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.
