The building of jetties or breakwaters, for example, may interfere with natural circulation features.
These so-called polar lows are most prominent in subpolar marine environments and are thought to be caused by the transfer of heat and moisture from the warmer water surface into the overlying polar air and by supporting middle-tropospheric circulation features.
Instrumental and paleo-proxy records of atmospheric circulation features relevant to spring flooding on the Lower Mississippi were also examined.
The effects of operating pressure on time-averaged solid-phase characteristics, solid circulation features, granular temperature and tube erosion patterns are analyzed.
It's incredible to think for example that we can sense from space very small circulation features like the Mann Eddy, a persistent pocket of water in the Atlantic that just goes around and around".
Scientists have found that this anomaly can affect atmospheric circulation features and produce persistent temperature and precipitation anomalies in many regions, such as wetter conditions along the west coast of tropical South America and subtropical latitudes of North and South America.
Experiments were carried out in specially designed molds with porous metal surfaces and fluid circulation features to generate foams with uniform dimensions at 60, 70 and 80 °C at pressures in the range 7 28 MPa.
On November 3, the depression was upgraded to Tropical Storm Greta as the circulation featured tropical characteristics.
The existence of such transients are also closely related to the formation of the Icelandic and Aleutian Low — the two most prominent general circulation features in the mid- to sub-polar northern latitudes.
Air pollution concentrations are the result of interactions among local weather patterns, atmospheric circulation features, wind, topography, human activities (i.e., transport and coal-fired electricity generation), human responses to weather changes (i.e., the onset of cold or warm spells may increase heating and cooling needs and therefore energy needs), and other factors.
