Sentences with phrase «increased aerosol loading»

Greenhouse gas forcing is expected to increase the interhemispheric SST gradient and thereby increase Sahel rainfall; hence, the recent Sahel drought has been attributed to increased aerosol loading cooling the Northern Hemisphere (75).

«The 1991 volcanic eruptions will substantially increase the aerosol loading within the polar vortex for 1992, both below and above 20 kilometres,» the team predicts.

SW fails to mention effects that may counter-act warming trends, such as irrigation, better shielding of the thermometers, and increased aerosol loadings, in addition to forgetting the fact that forests were cut down on a large scale in both Europe and North America in the earlier centuries.

An increasing aerosol load due to human activities decreases regional air quality and the amount of solar radiation reaching the Earth's surface.

«Recent satellite observations, however, have yielded contradictory results: LWP can decrease with increasing aerosol loading.

Not exact matches

«The increase in ammonia has spiked aerosol loading in China.

The Hadcm3 model has calculated the largest increase in temperature which may be attributed to the reduction of aerosol load (40 %) over the period 1990 - 1999 somewhere in NE Europe, other models do that more in Southern Europe.

And I forgot to mention that the aerosol load from Chinese industry and transportation HAS increased.

Possible attribution for MWP is a slight increase in TSI (increased solar luminosity and decreased volcanism / stratospheric aerosol loading).

«since the mid 1980s a significant increase in visibility has been noted in western Europe (e.g. Doyle and Dorling, 2002), and there are strong indications that a reduction in aerosol load from anthropogenic emissions (in other words, air pollution) has been the dominant contributor to this effect, which is also referred to as «brightening».»

2 / Increased sulphate aerosol loading from both anthropogenic (Hansen & Sato 2011 Earth's energy imbalance and its implications) and volcanic sources (Vernier et al 2011)

Li et al., 2017 (DOI: 10.1016 / j.quascirev.2017.01.009): «Additionally, increased El Nino - Southern Oscillation (ENSO) strength (possibly El Ni ~ no - like phases) during drying periods, increased volcanic eruptions and the resulting aerosol load during cooling periods, as well as high volumes of greenhouse gases such as CO2 and CH4 during the recent warming periods, may also play a role in partly affecting the climatic variability in NC, superimposing on the overall solar dominated long - term control.»

The projected radiative - forced increase of extreme surface temperatures and stronger spring barrier for wet season onset (Cook et al., 2010a; Seth et al., 2011) would increase risk of forest fires (Golding and Betts, 2008), although how changes of ENSO, AMO, and aerosols loadings will influence future droughts remain unclear (e.g., Andreae et al., 2005).

There is also a fairly large increase in modelled sulfate load over the Tropical North Atlantic from about 1960, which is presumably the main cause of modelled present day strong aerosol forcing off the West African coast, as depicted in Booth et al. figure 4b.
