A rare hole has opened up in the ozone layer above the Arctic, in what scientists say is the result of unusually low temperatures in the atmosphere above the north pole. The hole, which has been (racked from space and the ground over the past few days, has reached record dimensions, but...
Heaviside layer - a region of the ionosphere (from 50 to 90 miles up) that reflects radio waves of medium length E layer, E region, Kennelly-Heaviside layer ionosphere - the outer region of the Earth's atmosphere; contains a high concentration of free electrons Based on WordNet 3.0, Farle...
1.A horizontal layer of material, especially one of several parallel layers arranged one on top of another. 2.GeologyA bed or layer of sedimentary rock that is visually distinguishable from adjacent beds or layers. 3.Any of the regions of the atmosphere, such as the troposphere, that occur ...
The boundary layer has an important influence on the behavior of the atmosphere as a whole, and activities involving the representation of the atmosphere such as climate modeling and numerical weather prediction cannot succeed without the boundary layer being represented in some detail. The main influe...
A soil surface is much less changeable in time than is a water surface, and thus it is much easier to characterize the surface roughness, which directly impacts the transfer of heat between the atmosphere and the surface. Surface roughness lengths for various types of terrain are shown in ...
We speculate what the implications might be. This work is a contribution to IPY project #038 (OASIS, Ocean Atmosphere Sea-Ice and Snow interactions in polar regions), sponsored by the Canadian Federal Government Program for the IPY (project OASIS-CANADA). 展开 ...
Results from the 2009 IPY-OASIS field project in Barrow, AK, will be presented to define the turbulence state of the atmospheric surface layer as well as the structure of the atmospheric boundary layer. There is evidence that vertical mixing in the lower atmosphere frequently, if not always, ...
Define inversion layer. inversion layer synonyms, inversion layer pronunciation, inversion layer translation, English dictionary definition of inversion layer. A layer of warm air overlying an area of cold, so that temperature increases with height. Dict
Coincidently, aerobic decomposition of the residual peat layer causes emissions of CO2 to seep into the atmosphere [7,8]. Therefore, cut-away peatlands with no after-use act as a long-term source of atmospheric carbon [9,10]. View article Review on bromine in solid fuels. Part 1: ...
