Sentences with phrase «resulting change in cloud cover»

And the pattern of sea surface temperature anomalies that arise in consequence of the flux of ozone into the troposphere (and the resulting change in cloud cover) is intimately related to the GPH anomalies.

As a result, changes in Antarctic clouds, such as the amount of ground they cover or how much radiation they absorb, can have ripple effects as far away as the tropics.

What will happen if the AO changes is an open question, at one side there may be less inflow of warmer air, at the other side, this may result in opposite changes in cloud cover...

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.

Svensmark (1998) later proposed that changes in the inter-planetary magnetic fields (IMF) resulting from variations on the sun can affect the climate through galactic cosmic rays (GCR) by modulating earth's cloud cover.

I am happy to agree with WebHubTelescope that the changes in observed cloud cover may be a result of increases in CO2.

It is unknown, to me at least, how much of each would be the result, but there are many other impacts of cloud cover fluctuations than just a change in reflectivity.

What will happen if the AO changes is an open question, at one side there may be less inflow of warmer air, at the other side, this may result in opposite changes in cloud cover...

It changes because of greenhouse gases, cloud and ice cover changes, land clearing, volcanoes, dust and soot in the atmosphere — all of the physical changes that result in a change in the radiative flux leaving the planet either as IR (heat) emissions or as reflected sunlight.

Henrik Svensmark and others have shown a long - term correlation between solar activity and global temperature and have hypothesized that this results from changes in galactic cosmic rays leading to changes in cloud cover.

You have not cited a third possibility (out of the infinite range of possibilities), no climate change associated with CO2 (due to, for example, cloud cover providing negative feedback), with current increase due to natural variability; or how about possibility four, that increase in CO2 concentrations are caused by the temperature rise, which is in turn caused by (for example) increased solar activity resulting in increased biomass activity etc. etc..

Students will investigate whether that stoppage resulted in any changes to cloud cover, temperature and / or radiation.

One last point related to my last post, is the extent / degree of magnitude of a more meridional atmospheric circulation pattern (N.H. especially) could influence snow cover, cloud cover, and precipitation amounts which could set up stronger positive climatic feedbacks, which could then result in an even more significant climatic change going forward.

Second, the big change was in the short wave as a result of cloud cover changes.

The most obvious changes in CERES is in SW as a result of secular cloud cover changes — a moderate decrease obviously.

What if reduced cloud cover changed this to 29 % and the albedo was reduced to 99.18 watts / m ^ 2 or increased to 31 % resulting in an albedo of 106.02 watts / m ^ 2?

But all those glaciers, sea ice and desert / grasslands and a -6 W / m2 increase in low cloud cover (IPCC feedback estimates) do not result in Zero Albedo change.

(2) Alternatively, FD events might only result in dynamic effects over winter cyclogenesis regions, and therefore may not necessarily produce direct changes in cloud cover (Tinsley & Deen 1991).

This is due to the difficulty in distinguishing a cold, bright object (i.e., a cloud) from an ice or snow covered surface: as a result of these difficulties ISCCP has been noted to mistake temperature changes for cloud changes at high latitudes (Rossow & Schiffer 1999; Laken & Pallé 2012).

Spencer has postulated elsewhere that natural factors, such as PDO swings, might be the underlying cause for changes in cloud cover, which result in changes in global temperature, IOW that clouds act as part of a natural forcing, rather than simply a feedback to anthropogenic (or other) forcing.

It was in fact 2 things an energy decrease from solar irradiance in the 11 year cycle and a change in cloud cover that is associated with ENSO resulting in less reflected SW — seen in the CERES data.

You will probably quote some papers on this topic with the -21 W / m ² forcing of clouds without mentioning that this is the total forcing of a cloud and not the forcing that results from a change in cloud cover from one percentage to another.

As there are not one but two sources of satellite data to show that all warming in the satellite era resulted from cloud cover change — we should not allow mere supposition dissuade us until such time as other evidence prevails.

The water vapor feedback mainly results from changes in humidity in the tropical uppertroposphere (2), where temperatures are far below that of the surface and the vapor is above most of the cloud cover.

Regional climatic changes played a role as well, which was particularly relevant in Amazon rainforests, which accounted for 42 % of the global NPP increase, owing mainly to decreased cloud cover and the resulting increase in solar radiation (note that it is basically impossible to determine how much of this increase in NPP is a result of recent global climate change vs. natural climate variability, although both are likely to have played a role).

Berkeley Lab researchers Dev Millstein and Surabi Menon found that atmospheric feedback — such as changes in cloud cover or precipitation — does have an important effect, resulting in different amounts of cooling in different cities, but that cool roofs and pavements are still beneficial for combating global warming.

The potential for changes in cloud cover as a result of the changes in sea ice makes the evaluation of the actual forcing that may be realized quite uncertain, since such changes could overwhelm the forcing caused by the sea - ice loss itself, if the cloudi - ness increases in the summertime.

But this amount could increase if nighttime cloud cover were to become more common in the future as a result of climate change.

It's a finding that should be reflected in current climate models to help scientists make more accurate predictions about future Greenland melt — and could become even more important in the coming years if cloud cover over the ice sheet were to increase as a result of climate change.
