Sentences with phrase «through air layers»

Without atmosphere the surface of the ocean or land would lose o (T ^ 4 — Ts ^ 4)(1) where Ts is the temperature of the space (about 4K) while in the presence of the atmosphere the heat losses are hc * (T — Tl)(2) and o (T ^ 4 — Tl ^ 4)(3) where (2) represents the heat transfer by convection (inclusive conduction) through the air layer and (3) corresponds to the net flow due to the heat exchange by radiation, Tl being the mean temperature of the air layer.

The chief characteristics of work from that decade, with its echoes of Hans Hofmann, are densely layered surfaces and the arbitrary petals of paint so evocatively described by Mel Gooding in his book: «They flicker and flash with the chromatic brilliancy of birds, fish or insects against the broken light of impasto and coagulation, or like volcanic debris falling through burned air, or like bright figures of water, air and fire against elemental grounds of pigmented earth.»

Metals such as steel and bronze are wrought into astonishing forms, such as the confident and calculated lines drawn by French artist Bernar Venet's «collapsed» layers of steel arcs or American artist Jedd Novatt's abstracted cubic structures that slice through the air in suspended motion.

As they gazed out over the great island that had lost its forests two thousand years ago, and looked out over the sea whose wild tuna fish populations have been diminished by 96 %, and enjoyed the fresh air that now contained 385 ppm of CO2, and maybe more, and at night looked at the stars through a thinned ozone layer they must wonder what went wrong.

Changes in convection and cloud formations through altered air moisture (CAPE) could have implications for the coupled mode mechanisms, as would a deeper thermocline (usually situated near the bottom of the warm surface layer).

In the context of climate and weather, the term convection often is meant to include the conduction and diffusion at the surface; these fluxes heat a thin layer as convection cools it, thus the tendency is that approximately the same flux continues from the surface through a short distance of air, changing from conduction and diffusion into convection along the way.

As far as I understand it, hurricanes actually warm the deeper layers (though they do temporarily cool the surface which adjusts through air - sea exchange very quickly after the storm has passed).

The towering clouds were so high that they punched through the troposphere (the lowest layer of the atmosphere where most weather occurs) and sent air loaded with ice crystals rushing into the stratosphere, a higher layer that normally contains very little moisture.

As the air progresses through the layers of mesh, it heats up, and since flow rate is low, the residence time is long and the air heats up to high temperatures (say 140 + F).

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.

I think you mean by conduction through the skin layer, where then the heat can be transferred into the atmosphere either by evaporation, sensibly to air molecules, or by radiation.

However, the transport of heat into the air might go through four channels, which are radiation, convection of the air in the air layer, heat conduction and evaporation.

We are in complete agreement: I think you mean by conduction through the skin layer, where then the heat can be transferred into the atmosphere either by evaporation, sensibly to air molecules, or by radiation.
