warm the upper air 6 miles above the tropical surface at twice or thrice the surface rate.
Not exact matches

warmer upper troposphere may eventually slowly
warm the oceans.
There is a disparity between

air.
When snowfall is high in Siberia, the resultant cold
air enhances atmospheric disturbances, which propagate into the
upper level of the atmosphere, or stratosphere,
warming the polar vortex.
Climate models generally predict that temperatures should increase in the
upper air as well as at the surface if increased concentrations of greenhouse gases are causing the
warming.»
It turns out that the
upper -
air records have not shown the
warming that should accompany the reported increases at the surface.
Add in that if it's the sun, the entire atmosphere will
warm, since there's just simply more energy put in to the system, whereas if it is CO2 or other blanketing method, there's no extra energy put in, therefore the ground will
warm and the
upper air cool (since the
upper air isn't getting the
warming from the lower layers it used to get and the lower layers aren't losing the heat they used to).
The lack of ozone is chilling the middle and
upper atmosphere, altering wind patterns in a way that keeps comparatively
warm air from reaching the surface.
The radiation to space is made less efficient by the existence of a
warm stratosphere above the
air, generating IR radiation from above, and limiting the net cooling of the
upper troposphere.
The official theory is that photons interacting with CO2 molecules in the
upper air give off heat that
warms that
air, which
warms the lower
air, which
warms the surface.
Just as it is officially predicted that CO2 - driven
warming will be greatest in the
upper air, which will in turn
warm the surface, so it is predicted that the near - surface
air will
warm the ocean surface, which will
warm the deeps.
The 2009 State of the Climate report gives these top indicators: humans emitted 30 billion tons of of CO2 into the atmosphere each year from the burning of fossil fuels (oil, coal, and natural gas), less oxygen in the
air from the burning of fossil fuels, rising fossil fuel carbon in corals, nights
warming faster than days, satellites show less of the earth's heat escaping into space, cooling of the stratosphere or
upper atmosphere,
warming of the troposphere or lower atmosphere, etc..
On January 30th, an
upper level low - pressure system combined with a
warm sub-tropical
air mass led to Tucson recording its wettest January day on record at 1.39 in (35 mm).
«Storms like Harvey are helped by one of the consequences of climate change: As the
air warms, some of that heat is absorbed by the ocean, which in turn raises the temperature of the sea's
upper layers.
So we both agree that
upper elevation
air must
warmed somehow, but he appears to be ignoring the dense Venusian clouds.
Considering the different density of
air, would you be so kind an calculate (a rough estimate is ok) how much cooler the
upper part would have to be to compensate for say a 1 °C
warming of the surface?
Which, in turn, pumps
warm lower atmosphere
air into the
upper atmosphere, where the IR path to space is far shorter.
It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «
warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to
air (absorbed by the
air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to
air and compensate for a part of the heat lost to the cosmos by the
upper layer of the water vapour displayed on figure 6 - C.
* the water vapour content of
upper layer of the
air (in blue figure 6 - D) will change by about 12 % / K near the tropopause and is reduced by the enhanced cooling of the 250 mbar layer; hence the water vapour radiation will the be from a «lower and
warmer» level, with a very significant spectral leverage of a factor of ten (400 cm - 1 for the water vapour w.r.t to 40 cm - 1 for the CO2).
The really cold Arctic
air is only in the lowest regions of the atmosphere (below say 5,000 feet), which GISS would fully see, while the satellite also sees
air above 5,000 feet and averages that «
warmer»
upper air with the cold surface
air.
Should the vortex be broken up by a gust, the lower half of the vortex would reestablish itself with new
warm spinning
air from below, and the
upper half of the vortex would fill from the bottom with high - level cool
air and die off.
When released into the
air, they float into the
upper atmosphere, where they stay for up to 260 years and rapidly
warm the planet.
Craig King - Further to Bob Loblaw's comments; that global surface
air temperatures are
warming faster than
upper ocean temperatures is well - observed and completely uncontroversial.
If a significant portion of heat were being lost from the ocean, then it must
warm surface
air temperatures, before reaching the
upper atmosphere and being radiated out to space.
During hot, humid summer weather, many urban areas experience heat inversions — cold
air in the
upper atmosphere holds much
warmer air close to the ground, sustaining higher - than - average temperatures and trapping smog.
Hurricanes can be thought of, to a first approximation, as a heat engine; obtaining its heat input from the
warm, humid
air over the tropical ocean, and releasing this heat through the condensation of water vapor into water droplets in deep thunderstorms of the eyewall and rainbands, then giving off a cold exhaust in the
upper levels of the troposphere (~ 12 km / 8 mi up).
The second issue is far more complex, namely the inter-relationship with other gases in the atmosphere and what effect it may have on the rate of convection at various altitudes and / or whether convection effectively outstrips any «heat trapping» effect of CO2 carrying the
warmer air away and upwards to the
upper atmosphere where the «heat» is radiated to space.
