Sentences with phrase «affects water vapour feedbacks»

You really need to account for the vertical structure of temperature (the lapse rate), and if you want your model to get a number of basic things right you need to include spectrally grey absorbers — plus the additional mixing in the troposphere (which depends on convection, and hence affects water vapour feedbacks) etc....

Not exact matches

What other things in the Earth system will change when it warms up that will affect how much SW radiation is reflected back into space [eg ice - albedo feedback, cloud changes] or affect what proportion of emitted LW radiation is allowed to escape to space [eg Water Vapour, cloud changes].

On the real planet, there are multitudes of feedbacks that affect other greenhouse components (ice alebdo, water vapour, clouds etc.) and so the true issue for climate sensitivity is what these feedbacks amount to.

This means that the water vapour greenhouse effect feedback depends on the surface specific heat, latitude and altitude; all of which affect temperature.

Introducing the snow / ice feedback also affects the amount of energy trapped by water vapour.

This radiative response by the system is due predominantly to increased thermal radiation, but it is modified by climate feedbacks such as changes in water vapour, clouds and surface albedo, which affect both outgoing longwave and reflected shortwave radiation.

In order of seniority, the seven feedbacks that seem outstanding are: Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing, Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing, water column mixing, etc..

This study therefore suggests the rapid response to CO2 forcing is (apart from a possible small negative response from LW water vapour) essentially confined to cloud fraction changes affecting SW radiation, and further that significant feedbacks with temperature occur in all cloud components (including this one), and indeed in all other classically understood «feedbacks».
