More meridonal jet stream tracks flowing around the world between the climate zones result in longer lines
of air mass mixing at climate zone boundaries.
When meridonal, the jet streams wander in loops further north and south, resulting in longer lines
of air mass mixing at climate zone boundaries, which creates more clouds.
The latter results in far longer lines
of air mass mixing with more clouds at those lengthened air mass boundaries.
16) The main cloud bands move more equatorward to regions where insolation is more intense and total global albedo increases once more due to longer lines
of air mass mixing.
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.
It now appears clear that when the sun is active the jets are more zonal (east to west) with short lines
of air mass mixing and less clouds whilst when the sun is less active the jets are more meridional (waving north and south) with longer lines
of air mass mixing and more clouds.
Not exact matches
A storm is in fact parasitic on the increase
of entropy which would result from the
mixing of warm moist and cold
air to form a uniform
mass.
And then there's its legendary nightlife with countless tapas bars, open -
air cafes, flamenco shows and dance clubs open till late and
mixed with
masses of restaurants serving mouth - watering Andalucian cuisine.
Isn't one important feature
of cooling the stratosphere by emitting heat absorbed by ozone from incoming shortwave radiation, that this cooling has little effect on lower parts
of the atmosphere since there is not much
mixing between these
air masses?
This
mixing of air masses also favors more storms and snow in the mid-latitudes.
During the positive AO phase there is little
mixing of atmospheric
masses between the Arctic and lower latitudes (mid-latitudes and subtropics) so the cold
air stays bottled up in the Arctic and mild
air dominates the mid-latitudes.
Low pressure systems develop under these conditions
of rising warm
air, which causes frontal systems to move,
mixing cold and warm
air masses.
As already said by Mike M, atmospheric
mixing is quite rapid, but the ITCZ delays the exchanges between NH and SH, allowing only about 10 %
of air masses exchange between the hemispheres.
This struggle to
mix warm
air and cold
air ends up creating distinct
air masses, and aloft at the tropopause a strong stream
of eastward flowing
air marks the boundary.
The
mixing ratio is the ratio
of the
mass of water vapor to the
mass of only the dry
air in the sample.
Mixing Ratio: Ratio
of the
mass of water vapor to the
mass of dry
air - grams per gram or grams per kilogram.
+ Symbols [green] are thought to be not indicative
of background conditions, and represent poorly
mixed air masses influenced by local or regional anthropogenic sources or strong local biospheric sources or sinks.
Such a shift reduces the amount
of cloudiness because the length
of the main
air mass boundaries greatly decreases with far less
mixing and less clouds generated globally.
