Sound travels through air as waves, which is why we can hear sounds from afar. 7 Wind Wind is the natural movement of air or other gases relative to a planet's surface. Wind occurs on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heat...
Long-duration wind speeds have various names associated with their average strength, such as breeze, gale, storm, hurricane, and typhoon. Wind occurs on a range of scales, from local breezes generated by heating of land surfaces and lasting tens of minutes, to global winds resulting from the ...
the rise in global Ocean Heat Content (OHC), although the model underestimates this increase, as discussed in the following section. The highest rate of solubility-driven deoxygenation occurs within the upper 300 m of the water column (Fig.3e), with non-solubility-driven changes becoming domin...
Wind, in climatology, the movement of air relative to the surface of the Earth. Winds play a significant role in determining and controlling climate and weather. A brief treatment of winds follows. For full treatment, see climate: Wind. Wind occurs becau
pressure gradient force. This slackening is related to the temperature structure of the storm. Air is warmer in the core of a tropical cyclone, and this higher temperature causes atmospheric pressure in the centre to decrease at a slower rate with height than occurs in the surroundingatmosphere....
Pressure gradient force acts to move the air from high pressure to low pressure. Diverting force affects the air from two ways: one is as diverting force of earth’s rotation for movements from the equator to poles or in the opposite direction. Winds, in general, are under the effect of ...
We suppose that this occurs when a large-scale gust or sweep from the boundary layer well above the canopy raises the shear at z = h above some threshold level at which the instability can grow fast enough to emerge from the background before it is smeared out by the ambient turbulence....
This conversion occurs mainly at oceanic ridges and seamounts. In addition, 0.3–1.4 TW is converted into near-inertial internal waves (NIWs) from high-frequency wind forcing5,6,7. From their generation, IWs exchange and redistribute energy across scales through different processes such as wave–...
In our results, the predicted cross-wind movement occurred most frequently at night during winter, the time when most hunting occurs, while downwind movement dominated during fast winds, which impede olfaction. Migration during sea ice freeze-up and break-up was also correlated with wind. A lack...
【8】One problem both teams face is aphenomenonknown as “cavitation”. This occurs because a fast movingsurface—such as ahydrofoilor apropellerblade—creates an area of low pressure at itsrear. That allowsvapourbubblesto form, causingturbulencethat can slow a boat and can even damage its str...
