Like trade winds and unlike the westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. [15] Due to the low sun angle, cold air builds up and subsides at the pole creating surface high-pressure areas, forcing an outflow of air toward the equator; [16] that outflow is deflected westward by the ...
In meteorology the Ellrod index is a technique for forecasting clear-air turbulence (CAT). It is calculated based on the product of horizontal deformation and vertical wind shear derived from numerical model forecast winds aloft. The deformation predictors are calculated using following information. Shearing deformation:
The westerlies, anti-trades, [2] or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude. They originate from the high-pressure areas in the horse latitudes (about 30 degrees) and trend towards the poles and steer extratropical cyclones in this general manner. [3]
The Center for Turbulence Research is a research consortium for studying turbulence. It is jointly operated by Stanford University and NASA , with Parviz Moin as its founding director. [ 1 ] Established in 1987, the Center for Turbulence Research is devoted to fundamental studies of turbulent flows.
The Bulk Richardson Number (BRN) is an approximation of the Gradient Richardson number. [1] The BRN is a dimensionless ratio in meteorology related to the consumption of turbulence divided by the shear production (the generation of turbulence kinetic energy caused by wind shear) of turbulence.
The lingering effects of a high pressure system will conspire with an approaching storm from the Midwest to make a mess across much of the East. East's wintry mix could make travel dicey. And yes ...
Millions along the East Coast felt the impacts of a rapidly strengthening storm system on Wednesday, with wind gusts reported in excess of 70 mph and heavy rainfall that caused power outages and ...
In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet.
