Not exact matches

Success of pollination and fertilisation is influenced not only by the amount of pollen transferred to a stigma of a conspecific flower [54 — 57], but also by the time the pollen is exposed to temperature, humidity and UV - radiation, and other factors reducing the ability of pollen grains» germination [58,59].

Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, while thermal radiation describes heat flow across large distances, such as heat emitted by the sun.

This change was made to combat the charge transfer efficiency (CTE) losses caused by radiation damage that the two WFC CCDs have suffered since being put into orbit by artificially increasing the background in the dark images.

Spectroscopy and Keeling plus radiation heat transfer calculations gives you around 630 ZJ added by added CO2 and around 1200 added by all added GHGs (Murphy et al, 2009).

CO2 (and some other gases) in the atmosphere are however more opaque to LWIR; they absorb that a chunk of that outgoing radiation and re-radiate it in all directions — so that a fraction less than half is re-radiated downwards; which has the effect of slowing the transfer of heat (by radiation) out of the atmosphere.

Ray's answer makes it obvious (for me) that reality is very complex and far from being explainable by simple, hand - made arguments for the general audience; that's why I think that trying to explain «simply» the very complex phenomena involved in radiation transfer is just lost time - and in my opinion the REAL issues associated with social impacts of GW are not primarily associated with the detailed physics of the phenomenon.

The excerpt I quoted says below windspeed that disrupts the skin layer, heat transfer occurs by «molecular processes» — my guess would be that includes include both radiation and evaporation — anyone know?

Actually there can be convection from the surface that is balanced by some of the radiation from within the troposphere, but in the approximation of zero non-radiative transfer above the tropopause, all the flux into the stratosphere must be from below (absent solar heating).

In equilibrium these would be balanced by upward transfer of infrared radiation emitted by the surface, by sensible heat flux (warm air carried upward) and by latent heat flux (i.e. evaporation — moisture carried upward).

Energy is transferred from the Sun to the Earth by radiation, because radiation can pass through a vacuum.

What I'm thinking is that the primary way that the energy captured by CO2 gets dissipated is not radiation, partly back to the surface, but primarily upwards convention as the kinetic transfer between gas molecules moves the heat rapidly throughout the atmosphere.

That violates the 2nd Law and is not a real transfer of thermal energy / heat, proven by the fact that it can't be collected like the 161W / m ² of solar radiation can be.

«When a system of bodies at different temperatures is left to itself, the transfer of heat which takes place always has the effect of rendering the temperatures of the different bodies more nearly equal, and this character of the transfer of heat, that it passes from hotter to colder bodies, is the same whether it is by radiation or by conduction that the transfer takes place.»

6 Transfer of Energy Through Space Once the Sun's energy reaches Earth, it travels through different materials by conduction, convection, and radiation.

For longwave radiation, the model documentation states: «Since cycle Cy22r3, two longwave radiation schemes are available in the ECMWF model, the pre-cycle Cy22r3 by Morcrette (1991), and the current longwave radiation transfer scheme, the Rapid Radiation Transfer Model (RRTM)transfer scheme, the Rapid Radiation Transfer Model (RRTM)Transfer Model (RRTM).»

That claim is too simple to be useful, ignoring a) the complex interaction of Boltzmann radiation with the surface, the clouds, the GHGs, and the like, and b) the various regimes in the tropics, each of which modifies and changes the overall energy balance by things like convection and latent heat transfer.

If the upper troposphere cools only by radiation (with probably some convection across the tropopause), but the surface transfers energy to the upper troposphere via radiation, convection, and evapotranspiration, why would the concurrent CO2 - induced warming be uniform?
