Sentences with phrase «air moves poleward»

As the air moves poleward, it cools, becomes more dense, and descends at about the 30th parallel, creating a high - pressure area.

Some air moves poleward, while the remainder moves equatorward.

Extratropical cyclones have three stages of expansion: the developing stage, in which an undulating wave develops along the front; the mature stage, in which sinking cold air sweeps equatorward west of the surface low - pressure centre and ascending warm air moves poleward east of the cyclone; and the occluded stage, in which the warm air is entrained within and moved above the polar air and becomes separated from the source region of the tropical air.

This unusual flow pattern allowed cold air to spill southwards and be replaced by warm air moving poleward.»

Not exact matches

As the air rises and moves poleward, it dries, cools, sinks, and returns back to the surface completing this atmospheric cycle both north and south of the equator.

A parcel of air picking up water vapor at (near) the ITCZ moves poleward as well as rising.

6) The main cloud bands move more poleward to regions where solar insolation is less intense and total global albedo declines via a reduction in global cloud cover due to shorter lines of air mass mixing.

As a result, the poleward - moving air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere.

Since warm air is being moved poleward at low altitudes, the wind flow is no longer associated with the direct heat engine of the Hadley cell.

At present they are limited to guesses about ENSO but have nothing adequate about any other oceanic cycles and nothing about air circulation shifts apart from seasonal changes and a simple observation that warming moves them poleward.

At the 60th parallel, the air rises to the tropopause (about 8 km at this latitude) and moves poleward.

A similar air mass rising on the other side of the equator forces those rising air masses to move poleward.

The air circulation systems move latitudinally poleward or equatorward depending on whether there is net cooling or warming of the air at a gradual if variable rate all the time and climate shifts in any given location depend mainly on the changing position of that location in relation to the latitudinal position of the major air circulation systems.

When a large surge of polar air moves equatorward it draws a pulse of energy from the oceans in the lower latitudes and pumps it into the stratosphere where most of that energy is pushed out to space but a portion is not pushed out and descends again thus strengthening the high pressure systems on the poleward side of the mid latitude jets.

xii) All regional climate changes are a result of movement in relation to the locally dominant air circulation systems which move cyclically poleward and equatorward.

The air circulation systems in both hemispheres move poleward and the ITCZ moves further north of the equator as the speed of the hydrological cycle increases due to the cooler stratosphere increasing the temperature differential between stratosphere and surface.

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.
