Sentences with phrase «pressure at the pole»

It clearly involves surface pressure at the poles — it says so — and is concerned with NH blocking patterns involving the polar annular mode in a low solar UV environment.

The gyres spin up with negative polar annular modes — high pressure at the poles push circumpolar wind and storms into lower latitudes.

UV interacts with stratospheric ozone modulating atmospheric pathways and varying surface pressure at the poles.

The negative state involves relatively high pressure at the pole pushing winds, cold air and storms into lower latitudes.

In the south low pressure at the poles increases the strength of the circumpolar current through Drakes Passage and constrain storms to the polar region — with significant implications for Southern Hemisphere hydrology.

When solar activity is high — the sea level pressure at the poles is low and storms are constrained to a tight circle at high latitudes.

Higher surface pressure at the pole pushes winds and polar storms into lower latitudes.

Ultimately the AO and the AAO closely reflect atmospheric pressure at the poles.

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.

Surface pressure at the poles is influenced by solar activity — including in the ultravoilet band with UV / ozone chemistry in the stratosphere.

«clearly driven by a top down solar mechanism involving UV / ozone interactions causing changing sea level pressure at the poles.»

It is suspected that solar UV / ozone chemistry modulate atmospheric paths and result in varying surface pressure at the poles.

They are called the Southern and Northern Annular Modes — and no one has moved away from surface pressure at the poles influencing storm tracks and ocean currents in both Hemispheres.

The climate seems clearly driven by a top down solar mechanism involving UV / ozone interactions causing changing sea level pressure at the poles.

Not exact matches

It was no surprise to hear Arsene Wenger talking this week about the pressure of being at the top of the Premier League, as his Arsenal side have suffered with it plenty of times, including over the last few weeks when the Gunners hit a slump after finding ourselves two points clear and in pole position to win the Premier League.

The clock's mechanical parts left its accuracy at the mercy of shifting temperatures, pressures and even Earth's gravitational pull, since pendulums swing faster at lower altitudes and at Earth's poles.

These and other studies also have found that being at the bottom of the totem pole leads to greater stress as a result of increased work loads and time pressures, as well as more job insecurity.

Solar's 2017 solo exhibition «Ground Control» at Barcelona's Galería Joan Prats featured works from her «Crushed by pressure» (2017) series: potter's - wheel - thrown ceramic forms that are held in tension with elastic cords, or clasped by metal poles as if aberrant prostheses were gripped by outsized chopsticks.

Yes we can compare the two locations, allowing for the thinner air at the pole the pressures are comparable, in any case [CO2] is given as mixing ratio in ppm not as a partial pressure.

This in turn also leads to lateral growth of the Walker Cell — and therefore pole - ward migration (on both hemispheres) of the subtropical subsidence zone, where air under downward force is compressed at the Earth surface and semi-perminent high pressure systems lead to strucutural drought and desertification.

The whole is a complex and dynamic system triggered by changes in atmospheric pressure zones at both the north and south poles.

So the westerlies fail in the southern hemisphere as atmospheric pressure rises at the south pole and also at 60 - 70 ° south.

It is well established that solar UV and ozone interact at the poles — changing sea level pressures.

At the equator: direct solar energy; warm temps; low pressure air rises and moves towards the poles.

At the poles: indirect solar energy; cold temps; high pressure air sinks and moves towards the equator.

In a positive SAM event sea level pressure over the pole is relatively low and pressure at sub-polar regions relatively high.

Every 11 years, the polarity of «pressure» / gravity at the North and South poles reverses in response.

Even if the temperature e.g. at the poles, the sink places, dropped 1 °C more than average, that doesn't make much difference: the current CO2 level at about 400 ppmv gives about the same partial pressure of 400 microatm everywhere over the oceans (minus a few % due to water vapour).

Polar vortices occur when an area of low pressure sits at the rotation pole of a planet.

In the positive phase the pressure is low at the pole and high at middle latitudes.

In the negative phase the pressure is not as low at the pole and not as high at middle latitudes.

When the pressure is low at the pole, then there is a stronger vortex of air circulating around 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.
