The stratosphere is the atmospheric layer between the troposphere and the mesosphere and extends from about 12 km altitude to about 50 km. |
|
There's always sand in the cogs somewhere, even if these days its the ionosphere, or the troposphere, where things get gritty. |
|
In the upper atmosphere during this season, westerlies dominate in the upper troposphere over most of the monsoon region. |
|
As a result, there is much less interaction between the lower troposphere air masses of the polar regions and middle latitudes. |
|
The two transmitted beams cross at the lower troposphere, bouncing back to the receiving end. |
|
The stratosphere extends above the troposphere to about 150,000 feet and is the region where the ozone layer is formed. |
|
Like nacreous clouds, these usually form slightly above the troposphere, in the dry and ice-free stratosphere. |
|
Also, the presence of stratospheric ozone sandwiched between the satellite and the troposphere makes seeing tropospheric ozone very difficult. |
|
In the troposphere, water exists as vapor in air, as liquid droplets in clouds, and as frozen ice particles in high altitude cirrus clouds. |
|
It extends from the Earth's surface to the tropopause, the name given to the boundary between the troposphere and the stratosphere. |
|
Like the Earth's atmosphere, Titan's atmosphere can be separated into the troposphere, stratosphere, and upper atmosphere. |
|
Another important climate forcing, volcanic aerosols, can also give a similar opposing trend between the stratosphere and troposphere. |
|
There is a likelihood of rapidly increasing surface temperatures unaccompanied by strong warming in the free troposphere. |
|
High-flying aircraft sample ambient air to monitor ozone levels in the troposphere. |
|
Because of the cloud spreading at the top, the height of the troposphere in the area can also be calculated. |
|
The warm front slopes gently up into the troposphere that has a direct bearing on the kinds of clouds that are produced. |
|
Surface warming leads to cumulus convection and release of latent heat, producing warm temperatures throughout the troposphere. |
|
The concentrations of ozone in the troposphere in turn exert a significant influence on the greenhouse effect. |
|
These are the predominant anthropogenic emissions deposited directly into the upper troposphere and lower stratosphere. |
|
The satellite water vapour sensor detects humidity primarily at middle and upper levels of the troposphere, above the low clouds. |
|
|
In the troposphere ozone is a chemical oxidant and major component of photochemical smog. |
|
It is divided into four stratified layers: the troposphere, the stratosphere, the ionosphere and the exosphere. |
|
One of the effects created by the superstorms in the movie is the pulling down of supercool air from the troposphere that freezes people in a matter of seconds. |
|
The boundary between the top of the troposphere and bottom of the stratosphere is the tropopause. |
|
Found in two layers of the atmosphere, the stratosphere and the troposphere. |
|
The atmosphere is divided into four layers based on temperature: the troposphere, stratosphere, mesosphere, and thermosphere. |
|
Within the troposphere the pressure, density and temperature all decrease rapidly with height. |
|
Furthermore, through many traditions, we know also that by the air of our breathing, we absorb cosmical particles coming from the troposphere. |
|
As well, while it is not required, a high-pressure area located at the top of the troposphere above the storm or growing disturbance can greatly help a tropical cyclone to form. |
|
When the earth's surface and troposphere become warmer the stratosphere will cool down. Hence, the critical temperature for ozone depletion will be reached more often and the ozone layer will be weaker. |
|
The tropopause, the boundary between the two layers, disappears over the poles in winter, allowing stratospheric air to sink back into the troposphere. |
|
The vertical distribution of the zonal windspeed can be linked to the latitudinal gradient of the temperature by assuming a cyclostrophic equilibrium in the troposphere and mesosphere. |
|
Stratosphere: The part of the atmosphere situated between the troposphere and the mesosphere with a thickness of 30 km, in which the temperature rises only slightly. |
|
By comparison, ice nucleation in supercooled water droplets is the controlling mechanism for the formation of high clouds in the upper troposphere. |
|
In the middle troposphere, stratiform clouds are known as altostratus. |
|
When the team corrected the erroneous corrections, the result agreed with the models of the troposphere and with records of the surface temperature. |
|
Scientists think this haze, which is created by power stations and cooking-fires, may be radiating heat into the lower troposphere, at altitudes in which glaciers are found. |
|
Because the satellites are looking down through the whole atmosphere, measuring the temperature of the troposphere requires subtracting the effects of the stratosphere the atmospheric layer above it. |
|
The vertical temperature variations of opposite direction in the troposphere and stratosphere induce sharply different atmospheric circulations in these two atmospheric regions. |
|
In the standard case, temperature decreases with height through the troposphere to the tropopause and then becomes relatively constant in the stratosphere. |
|
|
Whether or not the events will become more intensive or not also depends on whether the stratification of the troposphere during the summer months becomes less stable as a result of climate change. |
|
Any volatile component degrades by reaction with hydroxyl radicals, in the troposphere, under the influence of sunlight, with half-lives less than one day. |
|
The amount of heat in the troposphere depends on concentrations of atmospheric greenhouse gasses and the amount of time these gasses remain in the atmosphere. |
|
That part of the atmosphere is more accurately known as the troposphere. |
|
The biggest issues relate to the climatological consequences of emissions resulting from aircraft flying at level cruising altitudes between the upper third of the troposphere through to the lower stratosphere. |
|
Within the troposphere there are gasses called greenhouse gasses. |
|
Aircraft emit gases and particles directly into the upper troposphere and lower stratosphere where they have an impact on atmospheric composition. |
|
The troposphere is the lower part of the atmosphere, where all the weather happens. |
|
Above the troposphere, the atmosphere is usually divided into the stratosphere, mesosphere, and thermosphere. |
|
In the vertical direction, winds are strongest near the surface and decay with height within the troposphere. |
|
If solar variations were responsible for the observed warming, warming of both the troposphere and the stratosphere would be expected. |
|
This steady descending airflow causes a warming and a drying effect in the upper troposphere. |
|
All share one important aspect, that of upward vertical motion within the troposphere. |
|
That is why most of the molecules collect close to the Earth's surface in the first atmospheric layer, called the troposphere. |
|
With Iceland's Grimsvotn spewing volcanic ash into the troposphere, Europe is on the brink of another potential holidaying disaster. |
|
While stratospheric ozone provides vital protection against harmful solar radiation, the same gas in the lower troposphere is a man-made pollutant and harmful to health. |
|
This weakening enabled a major trough to form and intensify up to the upper troposphere, 200hPa level and, by model prognostics, shape into a neat cut-off vortex pattern. |
|
The subsidence of the Sahara High nearly reaches the ground during the coolest part of the year while it is confined to the upper troposphere during the hottest periods. |
|
The deep layer mean flow, or average wind through the depth of the troposphere, is considered the best tool in determining track direction and speed. |
|
At an inner radius, air begins to ascend to the top of the troposphere. |
|
|
Tropical cyclones are areas of relatively low pressure in the troposphere, with the largest pressure perturbations occurring at low altitudes near the surface. |
|
As the aerosols grow and coagulate, they settle down into the upper troposphere where they serve as nuclei for cirrus clouds and further modify the Earth's radiation balance. |
|
A key part of the coupling between the troposphere and stratosphere occurs through the propagation and breaking of planetary-scale Rossby waves and gravity waves. |
|
The methane clouds in Titan's troposphere form in a similar way. |
