Dr Martin Ziegler, Cardiff University School of Earth and Ocean Sciences, said: «We found that South Africa experienced rapid climate transitions toward wetter conditions at times when the Northern Hemisphere experienced extremely cold conditions.»

The Arctic took another 3,000 - 4,000 years to warm this much, primarily because of the fact that the Northern Hemisphere had huge ice sheets to buffer warming, and the fact that changes in ocean currents and Earth's orbital configuration accelerated warming in the south.

The study, co-authored by Dr Thomas Stevens, from the Department of Geography at Royal Holloway, University of London, found a previously unknown mechanism by which the joining of North and South America changed the salinity of the Pacific Ocean and caused major ice sheet growth across the Northern Hemisphere.

The Southern Hemisphere, which includes the southern Indian Ocean from the coast of Mozambique across Madagascar to the coast of Australia, into the South Pacific and Coral Sea, saw below normal activity as well in 2008.

And meanwhile down south exactly the same thing happened as in the far north, although [due to the reversed situation of a central continent and surrounding seas — instead of a central ocean, surrounded by land masses] with exactly the opposite effect: the Antarctic sea ice reached its highest ever extent during the Southern Hemisphere winter.

The northern hemisphere has warmed faster than the southern because there's more land in the north than the south, and land has far less thermal inertia than ocean.

While these three types of measurements together suggest that our estimates of northern hemisphere ocean warming are about right, a different story emerged for down south.

Two reasons why this should be so in the real world are that, first, the Southern Hemisphere subtropical gyres are situated mostly in the Southern Ocean and South Atlantic, and second, that some of the heat coming into the Pacific Ocean basin doesn't actually stay there.

By comparing the hemispheres to the tropical temperatures, you can see the shift of heat content from neutral, to north or south and the different amplification due to the land / ocean ratio of the hemispheres.

It was predominantly warmer than average over the extratropical oceans of the southern hemisphere and over the North Pacific, but colder than average to the south - west of South Amesouth - west of South AmeSouth America.

A new Indonesian coral - based record of surface ocean salinity shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone (SPCZ), a band of high clouds and precipitation, influences a major current in the far western Pacific Oocean salinity shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone (SPCZ), a band of high clouds and precipitation, influences a major current in the far western Pacific OceanOcean.

Isaac Held considered north vs south hemispheres which is really an imbalance of ocean vs land temperatures.

Webster, «Isaac Held considered north vs south hemispheres which is really an imbalance of ocean vs land temperatures.»

With the approach of winter, temperatures in Northern Hemisphere begin to cool more rapidly — and the region of maximum north - south temperature differential over the Pacific Ocean starts to shift southward.

The more recent suggestion is that it is triggered by changes in polar surface pressure which modulate wind and ocean currents in both the north and south hemispheres.

The southern hemisphere tropical cyclone season normally runs from November to April and so far this season activity in the South Pacific Ocean has been relatively low.

This disrupted the warm ocean flow of water from the Southern hemisphere to the Northern Hemisphere, which caused the North to cool and the South themisphere to the Northern Hemisphere, which caused the North to cool and the South tHemisphere, which caused the North to cool and the South to warm up.

Once North and South American continents walled off eastern from western hemispheres, global atmospheric - ocean circulation patterns apparently lent themselves to regularly recurring chill phases.

Presenting their work at a recent European Science Foundation (ESF) conference, a group of scientists predicted that the saltiness of the waters of the southern hemisphere oceans around South Africa and New Zealand could serve as an early indicator of

«Skinner at all then argue that the oceans transmitted the signal from the warming North (Milancovitch) to the South (by shutting down the Meridional Overturning Circulation (MOC)-- heat remains in the Southern Hemisphere, which would melt sea - ice, which leads to more mixing / upwelling of the deep ocean as the ocean is not «protected» by sea - ice anymore).

Part of the explanation is probably due to the fact that temperatures are more stable in the Southern hemisphere (since land heats and cools faster than ocean, and there is much more ocean in the southern half of the globe), but the surface temperature records do not show such a north - south differential.

Subarctic Climate Occurs mainly in Northern hemisphere south of Arctic Ocean Winters are long and bitterly cold; summers short and cool Below freezing half the year Tundra Climate Coastal areas along the Arctic Ocean Long, bitterly cold winters In some parts is permafrost, or permanently frozen layers of soil Ice Cap Climate North and South poles Temperature lows of more than - 120 F Snow and ice remain year - round, but little precipitation Highland Climate Found on mountains Includes polar climates plus others; several climates in one As you go up a mountain, temperatures drop and plant life grows spasouth of Arctic Ocean Winters are long and bitterly cold; summers short and cool Below freezing half the year Tundra Climate Coastal areas along the Arctic Ocean Long, bitterly cold winters In some parts is permafrost, or permanently frozen layers of soil Ice Cap Climate North and South poles Temperature lows of more than - 120 F Snow and ice remain year - round, but little precipitation Highland Climate Found on mountains Includes polar climates plus others; several climates in one As you go up a mountain, temperatures drop and plant life grows spaSouth poles Temperature lows of more than - 120 F Snow and ice remain year - round, but little precipitation Highland Climate Found on mountains Includes polar climates plus others; several climates in one As you go up a mountain, temperatures drop and plant life grows sparser.

Cloud amount and albedo decreased over mid-latitude oceans in both hemispheres (especially over the North Atlantic), over the southeast Indian Ocean, and in a northwest - to - southeast line stretching across the central tropical South Pacific.»

In this paper the output from several different runs of a global ocean GCM is used to show that the inflow of upper kilometer water in the South Atlantic and the outflow of deep water varies in direct proportion to the westerly wind stress in the circumpolar region of the southern hemisphere.
