Sentences with phrase «only radiative fluxes»

Not exact matches

(Note that radiative forcing is not necessarily proportional to reduction in atmospheric transparency, because relatively opaque layers in the lower warmer troposphere (water vapor, and for the fractional area they occupy, low level clouds) can reduce atmospheric transparency a lot on their own while only reducing the net upward LW flux above them by a small amount; colder, higher - level clouds will have a bigger effect on the net upward LW flux above them (per fraction of areal coverage), though they will have a smaller effect on the net upward LW flux below them.

That the radiative flux can be measured isn't relevant because only the net energy transfer is relevant.

6 are determined entirely by a choice of the only free parameter l, which can be expressed in terms of a critical threshold of net radiative flux r c, below which no physical solution exists (Fig. 5).

You would do better to discuss why FG were not sure of their result for various practical reasons, e.g. the net radiative flux imbalance at the top of the atmosphere has only been measured for a very short time, and their study doesn't include albedo forcings from melting ice — if you're actually as interested in their results as you pretend to be.

In air, the radiative heat transfer flux for 0.9 emissivity steel only exceeds natural convection at c. 100 deg C. For aluminium it's about 300 deg C. Check any of the standard engineering texts, e.g. McAdam «Heat Transfer» to confirm (it's in the tables of combined heat transfer coefficients).

«Because the solar - thermal energy balance of Earth [at the top of the atmosphere (TOA)-RSB- is maintained by radiative processes only, and because all the global net advective energy transports must equal zero, it follows that the global average surface temperature must be determined in full by the radiative fluxes arising from the patterns of temperature and absorption of radiation.»

The result is that the aerosols are the only thing affecting radiative fluxes, including the changes they induce in clouds, etc..

We only have to refrain from converting it to a radiative flux change.

Air temperature is a nonconservative, intensive variable whose local value depends not only upon the radiative fluxes driven by thermalization of insolation, but upon upon the atmoshperic pressure, in accordance with Boyle's law.

In all calculations of A, TA, t A, and of the radiative flux components, the presence or absence of clouds was ignored; the calculations refer only to the greenhouse gas components of the atmosphere registered in the radiosonde data; we call this the quasi-all-sky protocol.

With this idealization the model climate, all statistics of the flow — temperatures, precipitation, clouds, radiative fluxes — are functions of latitude (and height) only, and not longitude or time of year, making for a much simpler system to analyze.

In all calculations of A, TA,, and of the radiative flux components, the presence or absence of clouds was ignored; the calculations refer only to the greenhouse gas components of the atmosphere registered in the radiosonde data; we call this the quasi-all-sky protocol.

The second method involves fixing the climate state at the start of the run (1850 in this case) and applying the cumulative time series for all of the forcing drivers to each year in turn, then running the radiative calculation (only) and recording the instantaneous net flux perturbation at the tropopause for each year in turn.

Regarding your complaint about the excessive referencing to my own articles I can only tell, that as soon as somebody else is willing to compute and write articles on the tau and the analytical relationships among the atmospheric radiative fluxes, I shall be happy to reference them.

Reality is that CO2's impact on downward radiative flux can be expected to be much less than water vapour's impact so not only is fa no bigger than 0.4 its probably very much smaller than 0.4 in reality.
