Sentences with phrase «sharp change in the lapse rate»

The warming effect near the tropopause level from CO2 can be explained by the relatively sharp change in the lapse rate.

A sharp change in lapse rate will (absent sharp changes in optical thickness per unit distance, which occurs at TOA and at the surface even in wavelength bands dominated by well - mixed gases) tend to differ from radiative equilibrium — the inflection point may correspond to a maximum deviation from radiative equilibrium if the radiative equilibrium profile has some intermediate lapse rate in that vicinity.

When optical thickness is large, the net flux will tend to be small, but the flux will vary with lapse rate (according to the corresponding Planck function «lapse rate») and a sufficiently sharp change in that lapse rate could lead to some significant flux convergence or divergence at that level (net radiant heating or cooling).
