during the year because the landmass in that hemisphere is relatively small. Apart from a thermal anticyclone over Australia during the southern winter, the centers of action are fairly stable over the oceans. The southern parts of the Atlantic, Indian, and Pacific oceans have three anticyclones over

The intensity of these systems vary during the year depending on the temperature of water and air. The action centers falter when the temperature contrasts decrease and conversely, they reinforce when these increases. Their position also varies, always following the maximum contrast.

areas which control the movement of atmospheric disturbances over a large area. This does not mean that the position of the center is constant over a specific area but that the monthly atmospheric pressure corresponds to a high or a low pressure.

Finally, in both hemispheres, there are centers of action inland in large continental zones where cold or warm air can be trapped by surrounding mountainous zones or high contrast or temperature by surrounding seas. This is the case for

The thermal contrasts over oceanic waters leads to the formation of these centers of action as a direct convective circulation is established between the equator and higher latitudes in a very weak 1660: 1655: 175:. Further South, a fairly continuous series of low pressure areas cover the ocean near Antarctica during the whole year and does the Antarctica High over the continent. 102:
Similarly, low pressure areas are formed in the oceanic circulation near the Polar regions were sea water is much warmer than the land. Such centers are the
