Sentences with phrase «increased water vapour»

These changes are associated with increased water vapour in the atmosphere arising from the warming of the world's oceans, especially at lower latitudes.
The amount of rain that tropical storms bring is also expected to increase as the planet warms, because of increasing water vapour.
But, if global temperatures increase from man - made global warming, this could increase water vapour concentrations, potentially leading to more warming.
Hence, even as the potential for heavier precipitation results from increased water vapour amounts, the duration and frequency of events may be curtailed, as it takes longer to recharge the atmosphere with water vapour.
Simulations with GCMs by Stevenson et al. (2000) and Grewe et al. (2001) for the 21st century indicate a decrease in the lifetime of tropospheric ozone as increasing water vapour enhances the dominant ozone sink from the oxygen radical in the 1D excited state (O (1D)-RRB- plus water (H2O) reaction.
Much of the warming feared by the alarmists relies upon a positive feedback involving increased water vapour exaggerating any CO2 warming effect.
Some point to aerosols (but that is not very plausible, as that should give an increase since 1975 for Europe and in part for North America), but I have the impression that increased water vapour levels are at the base of this change.
Global warming could correlate with increased water vapour, methane too, but CO2 as well.
Higher SSTs are generally accompanied by increased water vapour in the lower troposphere (see Section 3.4.2.1 and Figure 3.20), thus the moist static energy that fuels convection and thunderstorms is also increased.
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.
Increase water vapour in the atmosphere = > increased GH effect.
The increased water vapour then amplifies the effect on temperature caused by the original increase in carbon dioxide.
«The study is the first to confirm that human activities have increased water vapour in the upper troposphere,» said Brian Soden, professor [continue reading...]
It is noteworthy that the influence of warmer temperatures and increased water vapour in the atmosphere (Section 2.5.3) are not independent events, and are likely to be jointly related to increases in heavy and extreme precipitation events.
Observations of trends in relative humidity are uncertain but suggest that it has remained about the same overall, from the surface throughout the troposphere, and hence increased temperatures will have resulted in increased water vapour.
Basic theory, climate model simulations and empirical evidence all confirm that warmer climates, owing to increased water vapour, lead to more intense precipitation events even when the total annual precipitation is reduced slightly, and with prospects for even stronger events when the overall precipitation amounts increase.
