lower atmosphere

lower atmosphere

[′lō·ər ′at·mə‚sfir]
(meteorology)
That part of the atmosphere in which most weather phenomena occur (that is, the troposphere and lower stratosphere); in other contexts, the term implies the lower troposphere.

lower atmosphere

The atmosphere may be divided into two parts viz. the lower and the upper atmosphere. The tropopause and the troposphere are known as the lower atmosphere. It is that part of the atmosphere in which most weather phenomena occur. The region above the tropopause is called the upper atmosphere.

(5) Aether is the bright, untainted upper atmosphere, as distinguished from Aer, the lower atmosphere of the earth.
That is a rather clear signature of reduced solar output resulting in a cooler upper atmosphere, while greenhouse gases have warmed the lower atmosphere and surface temperature.
We contend it would increase the ionization of the lower atmosphere by 50-fold.
If we are venting more of this molecule into the lower atmosphere, we are producing something that can create a positive feedback loop in the climate system.
Formation of smog, however, is not dependent only on the presence or increase of these pollutants, but certain meteorological and weather conditions also help these pollutants suspend in the lower atmosphere because of which the pollutants form a dense visible layer of smog.
The study carried out under the 'Remote Sensing for Spatio-Temporal Mapping of Smog' project in collaboration with the Punjab government, found that the formation of smog, however, was not dependent only on the presence or increase of these pollutants, but certain meteorological and weather conditions also help these pollutants suspend in the lower atmosphere because of which the pollutants from a dense visible layer of smog.
However, formation of smog is not dependent solely on the presence or the increase of these pollutants; certain meteorological conditions help these pollutants become suspended in the lower atmosphere which forms a dense, visible layer.
The devices will be attached to migratory birds and will reveal the environments experienced by birds in flight and provide new insights into the dynamics of the lower atmosphere.
Storm tracks can change location over a period of years, and when studying the causes of such variation, researchers have primarily focused on the upper portion of the lower atmosphere. But a team from Stony Brook University looked to a different part of the atmosphere and discovered that activity higher up, in the stratosphere, is having a significant impact on Northern Hemisphere storm tracks.
Suspended matter accumulates in the lower atmosphere, colliding with water vapour which causes a chain reaction that produces smog.
The (https://www.eso.org/public/news/eso1729/) European Southern Observatory explained that when it is concentrated enough, it acts as a barrier that stops heat from entering or exiting, which would make the upper atmosphere of this exoplanet hotter than the lower atmosphere - a reversal of normal conditions.
