14 OCEAN CURRENTS Cold and warm streams of water move through oceans (based on earth's rotation, differences in water temperature, and change in air pressure.

One theory is that the warm Arctic could be influencing the jet stream — a band of fast - flowing air high up in the atmosphere.

22 Cause and Effect La Nina Cause: Stronger than normal trade winds push warm water farther west Effect: Polar jet stream is amplified, brings cold air to northwest.

Sea ice this year is melting at a pace two to four weeks faster than normal as pulses of warm air have been streaming into the Arctic from eastern Siberia and northern Europe and sea ice has retreated early from the Beaufort Sea.

One hypothesis suggests that the shrinking temperature difference between the Arctic and the mid-latitudes will lead to a slowing of the jet stream, which circles the northern latitudes and normally keeps frigid polar air sharply separated from warmer air in the south.

Warm surface air creates more thunderstorms over the central and eastern pacific Effect: Subtropical jet stream is energized, storms lead to frequent mudslides in SO. CAL.

Slower winds could create wilder swings of the jet stream, allowing warm, moist air to penetrate farther north.

The open cycle consists of the following steps: (i) flash evaporation of a fraction of the warm seawater by reduction of pressure below the saturation value corresponding to its temperature (ii) expansion of the vapor through a turbine to generate power; (iii) heat transfer to the cold seawater thermal sink resulting in condensation of the working fluid; and (iv) compression of the non-condensable gases (air released from the seawater streams at the low operating pressure) to pressures required to discharge them from the system.

The heat and moisture that are then released to the atmosphere in fall and winter could be leading to disturbances of the jet stream, the high - altitude wind that separates warm air to its south from cold air to the north.

A good point as arctic regions that are hit with warmer water streams will prevent sea ice extent while those with colder ones can massivly increase in volume when the air is cold enough though no growth would be visible from the top down view.

The northern and southern jet streams, which mark where cold and warm air meet, also seem to be creeping toward the poles.

[13] According to Arctic researcher Jennifer Francis, «The Arctic warmth is the result of a combination of record - low sea - ice extent for this time of year, probably very thin ice, and plenty of warm / moist air from lower latitudes being driven northward by a very wavy jet stream.»

And the very same jet stream configuration responsible for the southward plunging Arctic air mass chilling the eastern United States is associated further to the west with a «ridge» of high pressure that is pushing the warm, moist subtropical Pacific air masses that would normally deliver plentiful rainfall (and snowpack) to California well to the north.

The more sluggish and persistent those meanders, the more persistent the patterns of regional warmth where the jet stream pulls warm air northward, and the regional cold where it pulls arctic air south.

One reason for this was jet stream patterns that pushed warm tropical air up into Alaska and nudged colder Arctic air down into the continental United States.

What we experienced was one of those big southward dips in the jet stream caused by warming air in the Arctic, in combination with a big northward swing over California and the Eastern Pacific.

And since the temperature difference between the Arctic and the tropics is narrowing, and since it's the temperature difference that drives wind and ocean currents, then the jet stream that normally whizzes around the Arctic circle — thus keeping frozen air in one place and separating it from the warm breezes of the south — is, the theory goes, slowing, thus allowing warm moist air to penetrate into the north.

Cornell and Rutgers researchers report in the March issue of Oceanography that the severe loss of summertime Arctic sea ice - attributed to greenhouse warming - appears to enhance Northern Hemisphere jet stream meandering, intensify Arctic air mass invasions toward middle latitudes, and increase the frequency of atmospheric blocking events like the one that steered Hurricane Sandy west into the densely populated New York City area.
