Sentences with phrase «upper atmosphere circulation»

Not exact matches

This deep convection, the most conspicuous feature of the tropical circulation, in the company of precipitation transports latent heat from the earth's surface to the upper atmosphere.

While this circulation is so slow that a blob of air may take decades to travel to the upper atmosphere, it impacts the chemical composition of the global atmosphere because many chemical properties are very different in the lower and upper atmosphere layers.

But the atmospheric circulation reverses direction twice a year, and strong winds have been revealed in the upper atmosphere by cloud tracking and the brief measurements the Huygens probe made in 2005 as it descended towards the moon.

This would actually not be true at sufficiently high latitudes in the winter hemisphere, except that some circulation in the upper atmosphere is driven by kinetic energy generated within the troposphere (small amount of energy involved) which, so far as I know, doesn't result in much of a global time average non-radiative energy flux above the tropopause, but it does have important regional effects, and the result is that the top of the stratosphere is warmer than the tropopause at all latitudes in all seasons so far as I know.

Above this, the region between 60 to 100 km is known as the mesosphere, and is a transition region between the lower winds, which whip the cloud tops around the planet in four days, and the circulation of the upper atmosphere, which is driven by the influx of solar radiation.

The ITCZ lies at the foot of the ascending branch of the Hadley circulation, and the circulation transports energy in the direction of its upper branch, because energy (or, more precisely, moist static energy) usually increases with height in the atmosphere.

The simulations resolve the flow in the upper atmospheres of the giant planets, with implicit links to the (convective) flow, mean meridional circulations and (likely magnetohydrodynamic) dissipation mechanisms at depth.

Would a drop in temperature of the upper atmosphere of say 500 °F have no effect on surface temperatures or atmospheric circulation patterns?

Judith Curry: The polar vortex is a circulation pattern in the upper atmosphere that influences surface weather.

The diurnal and seasonal variations add, however, to the circulation but can not lead to more net transfer of heat to upper altitudes than the optically thin atmosphere can lose by net IR (emission - absorption).
