Sentences with phrase «aerosol clouds due»

There have been some regional aerosol clouds due to mankind's activity.

Not exact matches

Although records are sparse, pan evaporation is estimated to have decreased in many places due to decreases in surface radiation associated with increases in clouds, changes in cloud properties and / or increases in air pollution (aerosols), especially from 1970 to 1990.

Much of this uncertainty is due to the complexity of aerosols and their interactions with and impacts on cloud processes and properties, as well as the wide range of scales on which these interactions occur.

Roughly two - thirds of this reflectivity is due to clouds and small particles in the atmosphere called aerosols.

Much of the uncertainty in projections of global climate change is due to the complexity of clouds, aerosols, and cloud - aerosol interactions, and the difficulty of incorporating this information into climate models.

Possible reasons include increased oceanic circulation leading to increased subduction of heat into the ocean, higher than normal levels of stratospheric aerosols due to volcanoes during the past decade, incorrect ozone levels used as input to the models, lower than expected solar output during the last few years, or poorly modeled cloud feedback effects.

What it shows is the effect of the structural uncertainty in individual GCMs (meaning that some of them are systematically high, others systematically low, due to flaws in the representation of the physics; most probably related to discretization / parametrization effects for clouds and / or aerosols).

However, there is a price of sorts — while locally the Asian Brown Cloud amplifies the greenhouse effect, globally it masks the greenhouse effect due to the aerosol - induced global dimming.

The details of the physics of different forcings (i.e. ozone effects due to solar, snow albedo and cloud effects due to aerosols etc.) do vary the feedbacks slightly differently though.

Natural clouds eventually drifted into view under the manmade over-story but they did not have the usual majestic appearance as they were «melted» into engineered clouds above due to the aerosol saturation.

Progress with respect to modelling the indirect effects due to aerosol - cloud interactions is detailed in Section 2.4.5 and Section 7.5.

The brownish color of the cloud (which is visible when looking at the horizon) is due to absorption of solar radiation at short wavelengths (green, blue, and UV) by organic and black carbon aerosols as well as by NOx.

An increased greenhouse effect due to humidity, CO2, aerosols or clouds is expected to produce a relative increase of the minima with respect to the maxima and a decrease of the diurnal range.

[~ 17 model years](Motivation: Variation in the climate response across models will be a function of (a) different climate sensitivity in the GCMs, (b) different impact of aerosols on climate (due to location with respect to clouds, water uptake, natural aerosols, mixing, etc), and (c) different 3D constituent fields from the composition models.

In understanding that there is a difference between climate in a bottle [add CO2] and climate in a complex world with negative feedbacks due to aerosols and cloud albedo.

Taylor, J.P., and A.S. Ackerman, 1999: A case - study of pronounced perturbations to cloud properties and boundary - layer dynamics due to aerosol emissions.

You could also ask Andrew Revkin to withdraw his still - standing claim that most of the aerosols in atmospheric brown clouds are due to biomass burning.
