Sentences with phrase «ozone heating effect»

Surprisingly, nobody seems to have actually observed this alleged greenhouse effect... or the ozone heating effect, either!

«Above about 50 km in altitude, the ozone heating effect diminishes in importance because of falling ozone concentrations, and radiative cooling becomes relatively more important.

Not exact matches

Increasing levels of ozone, in turn, trap more heat, exacerbating the urban heat island effect: Cities are normally about five to 10 degrees hotter than surrounding suburbs because asphalt and cement absorb sunlight, generating a vicious cycle of escalating pollution and heat.

But ground - level ozone — the chemical combustion product of factory and vehicle emissions heated by sunlight — can have a devastating effect.

Gary Cohen, president and founder of the Massachusetts - based nonprofit Health Care Without Harm, said in a telephone interview that the risks of climate change to both the health of U.S. citizens and the U.S. health care delivery system is profound, particularly in urban areas, where warming average temperatures are exacerbated by the heat island effect and high concentrations of other air pollution like ozone and particulate matter.

The exaggerated effect in summer may be due to the heat cooking up air pollutants from fossil fuels, creating ozone - rich smog.

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.

In the «Ozone» series of the 1990s, hazy, fluorescent sparks of orange were splashed upon placid blue skies, suggesting indeterminate atmospheric effects of global warming, smog, sun, and heat.

Isn't one important feature of cooling the stratosphere by emitting heat absorbed by ozone from incoming shortwave radiation, that this cooling has little effect on lower parts of the atmosphere since there is not much mixing between these air masses?

I didn't know anything about the mesospheric effect at the time of your last comment, but I've looked into it a little bit since then, and I gather that there is non-CO2 heating there involving ozone as well as a variety of chemical reactions.

The upper part of the ozone layer contributes to net LW cooling there — of course, this includes the effect of solar heating on the stratospheric lapse rate.

Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).

There is growing evidence from EuroHEAT that the effects of heat - wave days on mortality are greater, particularly among the elderly, when levels of ozone or particulate matter are high.

This leads to the «greenhouse effect» theory and the «ozone heating» model for the stratosphere.

Even aside from that, the greenhouse effect theory makes fairly specific theoretical predictions about how the rates of «infrared cooling» and «ozone heating» are supposed to vary with height, latitude, and season, e.g., Figures 8 and 9.

Effect on atmospheric ozone of U.V. Effect on sea surface biology of U.V. Effect on ocean kinematics of solar variation — not all solar energy ends up as heat.

the greenhouse effect is an increase in the average temperature of the earth «Greenhouse gases» such as water vapor, carbon dioxide, ozone and methane, slow the escape of heat from earth's atmosphere.

Changes in clouds between these two runs should be driven by the aerosols (with a minor contribution from ozone via a semi-direct local heating effect).

Forster et al. (2007) described four mechanisms by which volcanic forcing influences climate: RF due to aerosol — radiation interaction; differential (vertical or horizontal) heating, producing gradients and changes in circulation; interactions with other modes of circulation, such as El Niño - Southern Oscillation (ENSO); and ozone depletion with its effects on stratospheric heating, which depends on anthropogenic chlorine (stratospheric ozone would increase with a volcanic eruption under low - chlorine conditions).
