大气atmospheric
大气倒置atmospheric inversion A temperature inversion in the atmosphere in which the temperature, instead of falling, increases with height above the ground. With the colder and heavier air below, there is no tendency to form upward currents and turbulence is suppressed. Inversions are often formed in the late afternoon when the radiation emitted from the ground exceeds that received from the sinking sun. Inversions are also caused by katabatic winds, that is cold winds flowing down the hillside into a valley, and by anticyclones. In inversion layers, both vertical and horizontal diffusion is inhibited and pollutants become trapped, sometimes for long periods. Low-level discharges of pollutants are more readily trapped by inversions than high level dischargers, hence the case for high stacks. Furthermore, high level discharges into an inversion tend to remain at a high level because of the absence of vertical mixing (大气中的温度倒置,在这种状况中,气温随着海拔的增加不减反增。由于下面更重更冷的空气,没有形成上升气流的趋势,湍流也被压制。倒置通常在下午晚些时候形成,这时候地面发出的射线超过了接收的来自下沉太阳的射线。倒置也会由下降风引起,这种风会以反气旋的形式从山上吹到山谷里。在倒置层,污染物的水平和竖直扩散都会被抑制从而被困住,有时会持续很长时间。低处的污染物放电比高处的更容易被倒置困住。而且,高处的污染物向倒置大气放电仍会保持在高处,因为缺少竖直混合。)

The fragile shield is being damaged by chemicals released on Earth.

海洋大气界面ocean-air interface The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water (海洋和空气彼此流动,但处于不同的能量状态--液体和气体。它们之间的自由表面边界抑制了,但绝不能完全防止,二者质量与能量的交流。当极端条件主导时,几乎所有穿过边界的交换变得非常有效。一个界限模糊的海面,水和空气性质之间的巨大差异或一个不稳定的空气柱,便于空气量从海面到高层大气的传送。高温和水(气)都倾向于穿过边界从海到空中方向移动。热交换有三个过程:辐射、传导、蒸发。最大的网络交流是通过蒸发,即从海到大气通过水蒸发的转化过程。)
