| atmospheric humidity (A measurable quantity of the moisture content found in the earth's atmosphere) | 大气湿度 | |
| atmospheric immissions | 大气注人［污染］物 | |
| 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) | 大气倒置 | |
| atmospheric layering (Any one of a number of strata or layers of the earth's atmosphere; temperature distribution is the most common criterion used for denoting the various shell. Also known as atmospheric shell; atmospheric region) | 大气分层 | |
| atmospheric model (A simulation, pattern or plan designed to demonstrate the structure or workings of the atmosphere surrounding any object, including the Earth) | 大气模型 | |
| atmospheric monitoring (A practice of continuous atmospheric sampling by various levels of government or particular industries) | 大气监测 | |
| atmospheric ozone (A triatomic molecule of oxygen; a natural constituent of the atmosphere, with the highest concentrations in the ozone layer or stratosphere; it is found at a level between 15 and 30 km above the Earth, which prevents harmful ultraviolet B radiation, which causes skin cancer and threatens plant life, from reaching the ground. The fragile shield is being damaged by chemicals released on Earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons (CFCs), which are used in refrigerators, aerosols and as cleaners in many industries and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine) | 大气臭氧 | |
| atmospheric particulate (A concentration of fine liquid or solid particles, such as dust, smoke, mist, fumes or smog, found in the atmosphere) | 大气微粒 | |
| atmospheric physics (The study of the physical phenomena of the atmosphere) | 大气物理 | |
| atmospheric pollution (The presence in the air of one or more contaminants in such a concentration and of such duration as to cause a nuisance or to be injurious to human life, animal life or vegetation) | 大气污染 | |
| atmospheric pollution | 大气污染〔浑浊〕 | |
| atmospheric precipitation (The settling out of water from cloud in the form of dew, rain, hail, snow, etc.) | 大气降水 | |
| atmospheric precipitation | 大气降水〔凝结〕 | |
| atmospheric precipitation | 露水 | |
| atmospheric precipitation | 雨量 | |
| atmospheric process (Atmospheric processes are distinguished in physical and chemical processes and both types may be operating simultaneously in complicated and interdependent ways. The physical processes of transport by atmospheric winds and the formation of clouds and precipitation strongly influence the patterns and rates of acidic deposition, while chemical reactions govern the forms of the compounds deposited) | 大气活动 | |
| atmospheric radiation measurement | 大气辐射测量 | |
| atmospheric science (The atmospheric sciences study the dynamics, physics and chemistry of atmospheric phenomena and processes, including the interactions of the atmosphere with soil physics, hydrology and oceanic circulation. The research focuses on the following areas: turbulence and convection, atmospheric radiation and remote sensing, aerosol and cloud physics and chemistry, planetary atmospheres, air-sea interactions, climate, and statistical meteorology) | 大气科学 | |
| atmospheric structure (The gaseous area surrounding the planet is divided into several concentric spherical strata (layers, like shells) separated by narrow transition zones. The boundaries are know as "pause". More than 99% of the total atmospheric mass is concentrated in the first 40 km from the Earth's surface. Atmospheric layers are characterized by differences in chemical composition that produce variations in temperature) | 大气结构 | |
| atrazine (Herbicide belonging to the triazine group, widely employed and particularly in maize crops. It is highly toxic for phytoplancton and freshwater algae and, being highly soluble in water, it easily contaminates aquifers) | 阿特拉津莠去津, 属于三嗪类的杀虫剂。被广泛应用在作物中，特别是玉米。对于浮游植物和淡水藻类有剧毒，容易污染含水土层。 |
