Sentences with phrase «cloud fraction changes»

The large rapid SW cloud response is related to cloud fraction changes — and not optical properties — resulting from small cloud decreases ranging from the tropical mid troposphere to the mid latitude lower troposphere, in turn associated with decreased lower tropospheric RH.

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».

Not exact matches

That would be a lot of noise needing to be filter out before determining any change in «normal» cloud cover fraction.

Svensmark 2009 was criticized by several papers including Laken et al. 2009 who found that the liquid cloud fraction variability was unrelated to the Forbrush events because «both the pattern and timing of observed LCF changes are irreconcilable with current theoretical pathways.

If you focus attention on the last 40 years, then the cloud cover change «explains» a large fraction of the temperature change.

The pattern of SW cloud fraction response to SST changes differs quite markedly to this, with large positive radiation responses originating in the upper troposphere, positive contributions in the lowest levels and patterns of positive / negative contributions in mid latitude low levels.
