Sentences with phrase «cloud height changes»

-- These storms should penetrate higher as climate warms according to the models, a positive feedback, and satellite data looking at cloud height changes over El Nino time scales show something similar and show the models getting that about right also, for physical reasons we think we understand

Not exact matches

This new research shows the first clear evidence of the long - term effects of pollution particles on cloud height and thickness, and how those changes both reduce precipitation in dry regions and increase precipitation in wet regions.

This fall, NASA will launch the Ice, Cloud, and land Elevation Satellite - 2 (ICESat - 2), which will use a highly advanced laser instrument to measure the changing elevation of ice around the world, providing a view of the height of Earth's ice with greater detail than previously possible.

According to thermodynamics and a largely fixed lapse rate, the average cloud height will simply shift up and down in altitude with change in temperature, which you can see in their Figure 2.

Regionally, changes in relative humidity near the surface would affect the height at which clouds form...

Now we have a couple of mechanisms that seem realistic for several specific types of changes such as the cloud height feedback, and we have some observational confirmation of a general latitudinal pattern of feedbacks that many models seem to get, more so than was the case a decade ago.

Ignore the movements of clouds; wind direction normally changes with height.

More surface warming than cloud - height warming is indicative of surface albedo change and / or fewer clouds and / or increase in solar «constant».

For instance, researchers still don't completely understand the role of aerosols in the atmosphere, the variable effects of clouds at different heights, and the influence of feedback mechanisms such as the changing reflectivity of the Earth's surface and the release of gases from permafrost or deep seabeds.

Only in this way is the energy balance determined empirically and the multitude of changes — cloud height and extent, water vapour, ozone, surface temperature, ice and snow, biology, aerosols — integrated in a comprehensible measure.

There can be interruptions when low cloud causes lower T, there can be nearby vegetation that casts a shadow on the screen sometimes, other vegetation effects like when mowed surrounding grass changes the effective height above ground of the thermometer, there can be a burst of rain that cools the surroundings — and so on into the night.

We know these clouds are related to low - level stability, but they also are affected by shallow convection, precipitation processes, and changes in the capping inversion height.

They note a reduction in the base height of low level clouds of approximately 7 m during dates of high GCR flux and based on periodogram analysis methods conclude that changes in the base height of stratiform clouds may show the presence of the 27 - day and 1.68 - year solar periods.

Cloud top height changes are quite well described by the fixed anvil temperature hypothesis of Hartmann and Larson; cloud base heights change little, remaining near the same presCloud top height changes are quite well described by the fixed anvil temperature hypothesis of Hartmann and Larson; cloud base heights change little, remaining near the same prescloud base heights change little, remaining near the same pressure.

There has been some changes in cloud height in the tropics though.

The SGM doesn't have clouds and even if you put in an absorber with a different scale height like water vapor, it's never saturated, so there are no phase changes above the surface.

Percent change in zonally - averaged cloud cover over the oceans as a function of latitude and height in response to an instantaneous quadrupling of CO2, decomposed into two parts: (a) a fast adjustment that occurs before surface temperatures have warmed appreciably, and (b) a part that scales linearly with the warming of surface temperature as the system adjusts to the increase in CO2.

Zhanqing Li, lead author of a paper published in Nature Geoscience and University of Maryland atmospheric scientist, says, «Using a 10 - year dataset of atmospheric measurements, we have uncovered the long - term, net impact of aerosols on cloud height and thickness and the resulting changes in precipitation frequency and intensity.»
