风的力量是它如此强大的原因。风刮的原因是空气从高压区流向低压区。风是强大的,这是为什么它是这样的。A 选项“what causes it”表示“什么导致它”,不符合语境;C 选项“how it happens”表示“它是如何发生的”,不符合语境;D 选项“that it is so”在这个语境中意思不明确。反馈 收藏 ...
1. Nautical As close as possible to the direction the wind is blowing from. 2. Close to danger. down the wind Nautical Downwind. in the wind Likely to occur; in the offing: Big changes are in the wind. into the wind Nautical In the same or nearly the same direction as the wind is...
: a gap or opening caused or appearing as if caused by damage : a condition produced by or as if by breaking : gap a break in the pipe breaks in the ice a break in the clouds waiting for a break in the traffic b : a gap in an otherwise continuous electric circuit 3...
Ocean deoxygenation is becoming a major stressor for marine ecosystems due to anthropogenic climate change. Two major pathways through which climate change affects ocean oxygen are changes in wind fields and changes in air-sea heat and freshwater fluxes.
S12.3 Playing wind instruments is associated with changes in blood pressure and heart rateListening to music, singing or playing music may induce cardiovascular changes [1 ] , which are largely dependent upon respiratory pattern. The principle for emitting a note is based on a sound source (...
Here winds are strongest, rainfall is heaviest, and deep convective clouds rise from close to Earth’s surface to a height of 15,000 metres (49,000 feet). As noted above, the high winds are driven by rapid changes in atmospheric pressure near the eye, which creates a large pressure ...
Regarding the issue of changes in the aerodynamic force of the bridge main beam under the action of wind-driven rain, this article explores the changes in air density caused by rainfall, the calculation theory of raindrop impact force and its simplified mass-weighted equivalent method (MWEM), ...
In the aviation industry and wind tunnel ducts, pitot tubes can measure static and dynamic pressure of the prevailing wind, which is then converted to airspeed using the Bernoulli equation. Despite their many advantages however, they are sensitive to wind flow direction, can become clogged by ...
which states that the sum of the forces acting on a body equals the product of themassof that body and theaccelerationcaused by those forces. The basic relationship betweenatmospheric pressureand horizontal wind is revealed by disregardingfrictionand any changes in wind direction and speed to yield...
