Collisions with wind turbines are a minor source of bird mortality compared to other human causes. The impact of wind energy on birds, which can fly into turbines, or have their habitats degraded by wind development, is complex. Displacement is thought to be more of a threat to species than collisions. [109]
Wind powers the voyages of sailing ships across Earth's oceans. Hot air balloons use the wind to take short trips, and powered flight uses it to increase lift and reduce fuel consumption. Areas of wind shear caused by various weather phenomena can lead to dangerous situations for aircraft. When winds become strong, trees and human-made ...
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
But wind chill isn't based on human comfort; rather, it's the rate that exposed skin loses heat because of the wind and cold. When the air is cold, your body naturally warms a thin layer of air ...
The warm and cold flavors of Santa Ana winds are generally rooted in the same dynamics. But cold Santa Ana wind events, Houk said, are driven by mid- and upper-level low pressure and colder air aloft.
The already serious cold is made more dangerous by gusty winds, which are bringing dangerous wind chills to millions. The wind chill hit 57 degrees below zero in Rolla, North Dakota, Monday morning.
The environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. [218] Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. [219]
In contrast, the Saffir-Simpson Hurricane Wind Scale focuses solely on wind intensity. When a densely populated area is in the path of a hurricane, more time is required for preparations and ...
