Sentences with phrase «change in cloud»

That increased atmospheric water vapor will also affect cloud cover, though impacts of changes in cloud cover on climate sensitivity are much more uncertain.

Change in cloud coverage was the primary cause of sea surface temperature variations, and clouds provided a positive feedback to temperature variations.

This effect causes a total swing of about three percent change in cloud cover.

The other possibility is that longer - term variations in solar wind could be responsible for changes in cloud formation triggered by cosmic rays.

Changes in cloud amount and cloud types might increase warming (positive feedback) or reduce it (negative feedback).

There is intriguing evidence from a brilliant little bit of astronomical engineering that shows a step change in cloud cover around the turn of the 21st century.

Your observations help scientists track changes in clouds, water, plants, and other life in support of climate research.

As an amateur, in my opinion the biggest «known unknown» is natural changes in cloud cover (and height and optical depth).

Yes, overall change in clouds may be a positive feedback, rather than a negative feedback assumed from simple ideas like more water - > more clouds - > cooling.

Changes in cloud geographical location and cloud amount are significant, but play a smaller role in driving radiative flux changes.

It will cause changes in clouds, rain, albedo, temperature and wind in ways that will alter climate patterns differently than solar visible light effects.

The planet moves past thresholds and the climate response is internally generated — with changes in cloud, ice, dust and biology — and proceeds at a pace determined by the system itself.

However, there have been several studies comparing observed changes in cloud cover to cloud simulations in climate models.

«The only thing that they showed that we didn't look at is changes in cloud cover and atmospheric moisture trends,» she said.

Changes in cloud cover do not offer an explanation for a cooling stratosphere.

It should be pointed out here, that the amount of change in downward heat radiation from changes in cloud cover in the experiment, are far greater than the gradual change in warming provided by human greenhouse gas emissions, but the relationship was nevertheless established.

Dr. Schmittner acknowledged another potential problem: that his computer analysis did not take good account of potential changes in clouds.

Its warming effect, however, is simultaneously amplified and dampened by positive and negative feedbacks such as increased water vapor (the most powerful greenhouse gas), reduced albedo, which is a measure of Earth's reflectivity, changes in cloud characteristics, and CO2 exchanges with the ocean and terrestrial ecosystems.

According to Gay, the projects were specifically selected to improve forecasts for two blocks of time: 24 to 48 hours in advance for day - ahead planning, when grid operators must manage projections for how to balance generation assets, especially on the transmission grid; and one to six hours in advance, when local weather events, cloud movements, or changes in cloud density can affect how much light is present.

Your statement that «Thus it is natural to look at the real world and see whether there is evidence that it behaves in the same way (and it appears to, since model hindcasts of past changes match observations very well)» seems to indicate that you think there will be no changes in ocean circulation or land use trends, nor any subsequent changes in cloud responses thereto or other atmospheric circulation.
