Sentences with phrase «overall effect of the clouds»

In a recent study, for instance, well - respected climate models were shown to have completely opposing estimates for the overall effect of the clouds and smoke in the southeast Atlantic: Some found net warming, whereas others found cooling.

Not exact matches

They tend to believe that as the planet warms, low - level cloud cover will increase, thus increasing planetary albedo (overall reflectiveness of the Earth), offsetting the increased greenhouse effect and preventing a dangerous level of global warming from occurring.

I was interested not so much in the forcing effect of clouds themselves so much as the change in albedo which might result from a change in the overall extent of global cloud cover.

Unknown is what the overall effect of greenhouse gases / temperature was / is / will be on cloud cover.

Spencer + Braswell have shown that over the tropics on a shorter - term basis, the net overall feedback from clouds with warming is negative; this is largely due to an increase in reflection of incoming radiation by increased clouds with a smaller effect from the reduction of energy trapping high altitude clouds, which slow down outgoing radiation by absorbing and re-radiating energy.

Stuart L I am a stupid layman, but wonder about the effects of water vapour (clouds) when I lived in the UK cloud conditions would cause the temps to be milder (warmer) here in Philippines cloud causes cooler conditions, how can one calculate the overall effect on the earths surface?.

I know that during the day time the overall change in influx will drop in the presence of clouds, but that at night a cloud will have the opposite effect, increasing influx.

DMS is the primary source in the sulfate mass budget over the remote ocean west of 80 ° W. • The first aerosol indirect effect has been observationally quantified over the SEP, with cloud thinning of the more polluted coastal clouds mitigating the overall radiative impact.

The overall effect of the high thin cirrus clouds then is to enhance atmospheric greenhouse warming.

It does magnify the night - time greenhouse effect by warming the clouds or the higher levels of the atmosphere, thus increasing the amount of heat radiated back to the surface; though the overall effect is to reduce net planetary greenhouse warming by limiting the temperature gradient.

As far as the overall heat balance is concerned, these are all negligible (some of them may of course have other effects — such as on cloud formation — that have a significant indirect impact on the heat balance).

The overall heat - trapping effect of cirrus clouds is so large that it exceeds that of human - released CO2, says Prof Ulrike Lohmann, an atmospheric scientist from ETH Zurich who recently published a review on cloud thinning in Science.

Hartmnn derived an average cloud radiative forcing of -27.6 W / m ^ 2 — a net cooling — as the overall average effect of clouds on global climate.

Here is what they say: «The balance between the cooling and warming actions of clouds is very close although, overall, averaging the effects of all the clouds around the globe, cooling predominates.»
