Tropical rainforests cover only about 6 % of the earth's land surface, but it is believed they have a significant effect on the transfer of water vapour to the atmosphere.

This is synonymous to a decrease in the transfer of water vapour.
Not exact matches
Alastair notes that increased water vapour will carry more energy to the surface of the glaciers, likewise these increased water flows over, through and under the glaciers is also transferring vast amounts of energy into the ice.
The conversion of a water molecule to a water vapour molecule involves a huge energy transfer from water to air so evaporation alone is a substantial factor.
(a) Convection accounts for approximately 67 % of the total amount of heat transfer from the Earth's surface to the troposphere, the condensation of water vapour for 25 % and radiation accounts for only 8 %.
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.
cementafriend, thanks for bring this up: «If convection occurs before radiation and the temperature of the atmosphere just above the surface is the same as the surface then it is clear that radiation to absorbing gases (CO2 and water vapour) will be zero because there is no net heat transfer between objects at the same temperature.».
