Sentences with phrase «aerosol concentrations lead»

Not exact matches

When the wind slows down, the concentration of small particles of air pollution (aerosols) increase, which help increase haze and leads to solar dimming in the area.

The results, said co-author and PNNL laboratory fellow Ruby Leung, «strongly suggest that increasing aerosol concentrations (particles, mainly soot and sulfur, that pollute the air) in the past has produced a fog - like haze that has reduced solar radiation (surface heat from sunshine), despite more frequent clear days that should lead to increased solar radiation.»

The new study, published in Nature Geoscience, identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling [continue reading...]

Because of the first of these reasons, were we to abruptly halt all emissions now, the sulfate aerosols would rapidly be removed from the atmosphere by precipitation whereas the CO2 concentration would remain elevated, and so there would be a significant further warming influence just as a result of past emissions; this warming would lead to the quite significant global warming that Lindzen mentions.

An increase in aerosols of similar hygroscopicity leads to an increase in cloud droplet number concentration that reduces the precipitation efficiency for warm clouds.

The new study, published in Nature Geoscience, identified a negative feedback loop in which higher temperatures lead to an increase in concentrations of natural aerosols that have a cooling effect on the atmosphere.
