Though cool and dry relative to
equatorial air, the air masses at the 60th parallel are still sufficiently warm and moist to undergo convection and drive a thermal loop.
So unless the air circulation becomes more zonal / poleward again we will continue to see more incursions of both polar and
equatorial air masses into the mid latitudes (with the greater extremes that implies) but with a generally cooling trend.
It guides the movement of mid latitude depressions and effectively marks an interface between warmer
equatorial air and colder polar air.
Thus, when the ocean circulations increase the resistor efficiency of the oceans by slowing the release of energy into the air then the air follows by increasing it's own resistor efficiency by exposing less
equatorial air to space.
It does that by means of the weather systems moving towards the equator and thereby reducing the size of
the equatorial air mass.
It does that by means of the weather systems moving towards the poles and thereby increasing the size of
the equatorial air mass.
Changes in climate can cause the polar jet stream — the boundary between the cold North Pole air and the warm
equatorial air — to migrate south, bringing with it cold, Arctic air.
As
the equatorial air warms up, it expands and rises.
Not exact matches
Spawned by the Sea Atlantic hurricanes often develop over
equatorial waters off the African coast, where colliding winds generate thunderstorms fueled by warm, humid
air.
Modelling the flow of
air within the atmospheres of these planets, Carone and her colleagues found that this unusual day - night divide can have a marked effect on the distribution of ozone across the atmosphere: at least for these planets, the major
air flow may lead from the poles to the equator, systematically trapping the ozone in the
equatorial region.
Rising
air over the Atlantic subsides over the
equatorial Pacific, causing central Pacific sea surface cooling, which in turn reinforces the large - scale wind anomalies.
In recent times, volcanic fallout has been known to interfere with an
equatorial belt of
air called the Intertropical Convergence Zone that seasonally shifts up and down around the world, bringing monsoon rains either north or south depending on the time of year.
Volcanic fallout is known from more recent times to interfere with an
equatorial belt of
air called the Intertropical Convergence Zone that seasonally shifts up and down around the world, bringing monsoon rains either north or south depending on the time of year.
In a new study, Ashfold and his team show that these «cold surges» can very quickly transport polluted
air from countries such as China to remote parts of
equatorial Southeast Asia.
«These chemicals enter the atmosphere at lower latitudes where they were used, and are then deposited down from the cold polar
air, so Arctic animals are more highly exposed than animals in more temperate or
equatorial regions,» University of Florida researcher Margaret James (who wasn't involved in the study) told New Scientist.
The
equatorial dash vent mixes horizontal and vertical
air jets to precisely angle the flow as you desire, controlled by moving a dot on a crosshair on the touchscreen.
As far as water vapor in the tropics, they even say» In the humid
equatorial regions, where there is so much water vapour in the
air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.»
In the humid
equatorial regions, where there is so much water vapour in the
air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.
As the diverted
air in the troposphere moves toward the poles, it tends to retain the angular momentum of the near -
equatorial region, which is large as a result of Earth's rotation.
As (relatively) warmer tropical
air slowly circulated (colder poles), first Earth's polar oceans would freeze, then the mid-latitudes, then even the
equatorial oceans.
Because the vertical sun travels back and forth across the
Equatorial regions — mostly ocean — the
air becomes warm and humid, and becomes buoyant.
If there is no cause of El Niño - La Niña, but it is an oscillation of the coupled
equatorial Pacific
air - ocean system, other oscillations are coupled with this one.
As reported by the IPCC in the Physical Science Basis, «In the humid
equatorial regions, where there is so much water vapour in the
air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.
Sorry I don't have graphs of surface
air temperatures or TLT for the tropical Pacific, but to help show this using sea surface temperatures, not anomalies, the following graph captures the sea surface temperature gradients across the
equatorial Pacific one year before the peak of the 1997/98 El Niño, at its peak, and at the peak of the trailing first La Niña season: And as sea surface temperature anomalies:
25 kg / m ² is about the global average of water vapour on the
air that goes from 1 or 2 kg / m ² (extreme winter polar conditions) up to 80 kg / m ² (near the
equatorial convective «chimney» at the confluence of the trade winds)
(Because of condensation during the
equatorial ascent, which hot wet tropical monsoons tend to dump on New Guinea, Bangkok, etc., the
air descending at 30 degrees ends up being pretty dry, but that's not super-important here.)
I also bet that regions with saturated
air rarely have temperatures go much above the temperature associated with saturation, ie the
Equatorial area would have stable rain forest temperatures and wild swings in the deserts.
On January 3 and 4, the first of two back - to - back atmospheric river storms (wide paths of moisture in the atmosphere composed of condensed water vapor), brought heavy rain and mountain snow to central California, ahead of an even more intense round of heavy precipitation brought by a powerful, long - duration atmospheric river storm pulling warm and moist
air to California from the subtropical and
equatorial region southeast of Hawaii.
The descended
air then travels toward the equator along the surface, replacing the
air that rose from the
equatorial zone, closing the loop of the Hadley cell.
The process begins when strong convective activity over
equatorial East Asia and subsiding cool
air off South America's west coast creates a wind pattern which pushes Pacific water westward and piles it up in the western Pacific.
Warm
air rises over the
equatorial, continental, and western Pacific Ocean regions.
It is this straight line
air movement which sets up the
equatorial current.
The tropical oceans take up vast amounts of energy through
air - sea heat fluxes, especially in the
equatorial regions dominated by wind - driven upwelling of cold water.
The ENSO cycle refers to the coherent and sometimes very strong year - to - year variations in sea - surface temperatures, convective rainfall, surface
air pressure, and atmospheric circulation that occur across the
equatorial Pacific Ocean.
