Sentences with phrase «expanding poleward»

Arid subtropical climate zones are expanding poleward.

While a 2009 estimate calculated that the tropical zone was expanding poleward at a rate of 222 to 533 kilometers every 25 years, the new report estimates that the expansion is occurring more slowly — between 138 and 277 kilometers per 25 years.

At the same time, tropical conditions are expanding poleward as a result of climate change, but at a slower rate than previously believed.

According to the study, as the planet warms, the Hadley Cell, which links together rising air near the Equator and descending air in the subtropics, expands poleward.

On global vs. local, how about the global model prediction of a deepening and widening of the tropical atmospheric circulation, which leads to the Hadley cell expansion and the projection of the dry zones expanding polewards.

The planet's boreal forests won't expand poleward.

Climate models show the southwest U.S. drying in the 21st Century as the tropical Hadley circulation expands poleward.

But climate models show a consistent tendency for areas such as the southwest U.S. to dry out in the 21st Century as the sinking branch of the tropical Hadley circulation expands poleward and carries drier air down to the surface [8].

Theory and climate models indicate that the tropical overturning (Hadley) atmospheric circulation expands poleward with global warming [33].

IPCC climate change simulations diagnose that the Hadley circulation will weaken and expand polewards as a result of climate change.

The water vapor envelope can expand poleward, but we are running out of poleward.

If the Hadley cells are to expand polewards with global warming, does that mean the ITCZ will have greater seasonal shifting, and is that an opportunity for greater interannual variability?

Recent work (Kossin et al. 2014; see GFDL Research Highlight) indicates that the latitude at which the maximum intensity of tropical cyclones occurs has expanded poleward globally in recent decades, although the causes for this have not been firmly established and a significant change was not seen in the Atlantic basin statistics.

Not exact matches

The dry, semi-arid regions are expanding into higher latitudes, and temperate, rainy regions are migrating poleward.

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.

Climate models predict expanding Hadley Cells as the climate warms, meaning a poleward expansion of the subtropical desert zones.

Spatial selection and local adaptation together thrust life - history evolution in a poleward - expanding arthropod

General warming is said to expand the equatorial Hadley cells, shrink the polar ones, and move the dry zones polewards - I was asking why.

Satellite temperature measurements show similar warming; most glaciers are shrinking; lakes and rivers are freezing later and thawing sooner; oceans are expanding; plant and animal communities are mostly moving poleward.

The conventional view on the connection between the AMOC and Arctic sea ice is that a weakening of the AMOC should reduce ocean poleward heat transport and, hence, expand sea ice.

23) A returning warm pulse will try to expand the tropical air masses as more energy is released and will try to push the air circulation systems poleward against whatever resistance is being supplied at the time by the then level of solar surface activity.

A returning warm pulse will try to expand the tropical air masses as more energy is released and will try to push the air circulation systems poleward against whatever resistance is being supplied at the time by the then level of solar surface turbulence.

It can be seen that most models produce radiative warming in the southern mid-latitudes as they expand their Hadley cells poleward.

Due to climate change the Hadley Cell intensifies: More air moves up in the tropics (so more energy and rain in the Intertropical Convergance Zon (ITCZ — monsoon) and more air moves down in the subtropics, that also expand in poleward direction.
