The gyres spin up with negative polar annular modes — high pressure
at the poles push circumpolar wind and storms into lower latitudes.
The negative state involves relatively high pressure
at the pole pushing winds, cold air and storms into lower latitudes.
Higher surface pressure
at the pole pushes winds and polar storms into lower latitudes.
Not exact matches
The effect is similar to what happens when a ball of dough is spun into a pizza crust — centrifugal force
pushes material
at the
poles out to the equator.
The solar jet stream, a slow current originating
at solar midlatitudes that
pushes toward both the equator and the
poles, provides a different window into the sun's roiling innards.
Exhilarating day today... I
pushed through my fear of heights (almost giving up
at the first step) and dangled precariously from a selection of
poles and ropes 400 feet up (well, over 40 anyway... much like myself!).
The new game mode is called Frontlines, and the premise is an interesting one: like a game of tug - of - war, you'll need to
push through each consecutive objective (and prevent the enemy team from doing so) in a chain before reaching the enemy HQ point,
at which point 2 telegraph
poles will have to be destroyed (or defended) a little like Rush.
If you look the same trend in Siberia, Northern Canada or Sea
at 80th parallel, all of them show a strong amplification and
push the average of North
pole temperature increasing.
[ANDY REVKIN comments: The Antarctic has seen no change in the extent of floating sea ice in recent years, in stark contrast to the situation in the Arctic, and all of this shows the Earth's climate system, particularly
at the
poles, is not simple — and thus not likely to follow a simple trajectory under a greenhouse
push from humans.
Chewing in energy from the
poles, and
pushing it out again
at the equator.
Since the whole world does not appear to freeze during a ice age, the must be massive ice making going
at the
pole driven by heat lifting oceans of water to the sky from the equator where it is
pushed by the expanding air and vapor to the
poles areas where it returns to the surface and follows cold land like a culvert between warmer expanding ocean air back down to the equatoral region.
The primary effect of the two tropical Hadley cells (one for each hemisphere) is for the rising hot air
at the equator to suck surface air from the higher latitudes (north and south) along the surface towards the equator, pump it vertically
at the equator, and
at a suitable height
push it polewards, one
pole per cell, up where the jet planes fly.
The Law Dome location suggests the involvement of the Southern Annular Mode — the belt of westerlies circling the Antarctic that are
pushed more or less into lower latitudes by surface pressure
at the
pole.
Because of the pressure gradient
at altitude between the tropics and the
poles, there is a force (
at altitude)
pushing air from the tropics to the
poles.
At each solar maximum, the corona sloughs off the magnetic fingerprint of the previous cycle by
pushing it to the
poles.
