Sentences with phrase «of high clouds»

It's even more dramatic when a thin layer of high clouds is present.

Those patterns matched three rather dire climate model predictions: that storm tracks — the paths along which cyclones travel in the Northern and Southern hemispheres — would shift poleward; that subtropical dry regions would expand, and that the tops of the highest clouds would get even higher.

Taking into account the obscuring effects of high cloud, it was found that thick low clouds decreased by more than 20 % in the eastern tropical Pacific... In contrast, most increase in low cloud amount due to doubled CO2 simulated by the NCAR and GFDL models occurs in the subtropical subsidence regimes associated with a strong atmospheric stability.»

Their idealized increase of high cloud amount has the strongest impact on global precipitation (see their table 4 below).

This means that when the Hadley cell extends poleward as the climate warms, the contraction of the high clouds remains largely unbalanced and the surface of the southern hemisphere oceans warms.

Observed and simulated cloud change patterns are consistent with poleward retreat of mid-latitude storm tracks, expansion of subtropical dry zones, and increasing height of the highest cloud tops at all latitudes.

Walking on moderate hiking trails to about 4,600 ft (1,400 m) above sea level, you can compare the biodiversity of the higher cloud forest to the lusher rainforest you've left behind.

Weather wise this morning there was alot of high cloud hanging around and some early morning rain falling down on the bukit.

This is because the contrails lead to the development of high clouds, cirrostratus, and they absorb the heat in the air.

abstract postscript pdf Pierrehumbert, RT 1996: Anomalous scaling of high cloud variability in the tropical Pacific.

In the northern hemisphere, the poleward movement of the high clouds opens up a «cloud curtain» that lets more sunlight into the ocean surface, thus producing warming at the surface.

A new Indonesian coral - based record of surface ocean salinity shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone (SPCZ), a band of high clouds and precipitation, influences a major current in the far western Pacific Ocean.

But in the southern hemisphere, the poleward contraction of the high clouds is balanced by an expansion of the already extensive low cloud decks, which ends up blocking more sunlight and producing a small surface cooling.

Observations alone do not currently provide a robust, direct constraint, but multiple lines of evidence now indicate positive feedback contributions from changes in both the height of high clouds and the horizontal distribution of clouds.

The temperatures at the tops of high clouds are much colder than the surface, and thus reduce the energy loss of the planet better than low clouds (which emit at temperatures rather close to that of the surface).

These ice crystals grow rapidly, drawing moisture from surrounding cloud droplets, become heavier and fall, generating more rain and reducing the total amount of high clouds.
