Among other things, giant
cell circulation helps transport energy from the sun's
polar regions to its equator, where material rotates around the sun about 10 days faster than it does near the poles.
For example, in Earth atmospheric
circulation (such as Hadley
cells) transport heat between the warmer equatorial regions to the cool
polar regions and this
circulation pattern not only determines the temperature distribution, but also sets which regions on Earth are dry or rainy and how clouds form over the planet.
For example, they predicted the expansion of the Hadley
cells, the poleward movement of storm tracks, the rising of the tropopause, the rising of the effective radiating altitude, the
circulation of aerosols in the atmosphere, the modelling of the transmission of radiation through the atmosphere, the clear sky super greenhouse effect that results from increased water vapor in the tropics, the near constancy of relative humidity, and
polar amplification, the cooling of the stratosphere while the troposphere warmed.
The
circulation patterns of the tropical Hadley
Cell, the mid latitude storm tracks the
polar high and the resulting climate zones are all driven by the gradients of solar heating as a function of latitude.
But over Antarctica, increased CO2 should also accelerate the
circulation of the
polar cell, and hence indirectly that of the mid-latitude
cell, and with it the west wind drift.
Simple and comprehensive general
circulation models (GCMs) indicate that the Hadley
cell may widen in response to global warming, warming of the west Pacific, or
polar stratospheric cooling.
The easterly Trade Winds and the
polar easterlies have nothing over which to prevail, as their parent
circulation cells are strong enough and face few obstacles either in the form of massive terrain features or high pressure zones.
The Brewer - Dobson
circulation is a large - scale
circulation cell with rising motion in the tropical stratosphere, poleward motion in the middle latitude stratosphere, and sinking motion in the
polar stratosphere.
Furthermore warm ocean surfaces really do send the air
circulation systems poleward whilst changes in the intensity of the
polar high pressure
cells work in opposition to those oceanic effects.
No computer necessary, only pen and paper and yet you get all the
circulation features right (Hadley
cells,
polar cells) and the model even predicts their location and dynamics.
