South Atlantic High

South Atlantic High is a semipermanent pressure high centered at about 25°S, 15°W, in the Atlantic Ocean. It is also called the St. Helena High. It can stretch thousands of miles across the South Atlantic affecting shipping. Sailors try to find a "corridor" through using the low pressure systems forming off the coast of Brazil that move west pushing against the high pressure.

Famous quotes containing the words south, atlantic and/or high:

    “Even when seen from near, the olive shows
    A hue of far away. Perhaps for this
    The dove brought olive back, a tree which grows
    Unearthly pale, which ever dims and dries,
    And whose great thirst, exceeding all excess,
    Teaches the South it is not paradise.”
    —Richard Wilbur (b. 1921)

    “There was not a tree as far as we could see, and that was many miles each way, the general level of the upland being about the same everywhere. Even from the Atlantic side we overlooked the Bay, and saw to Manomet Point in Plymouth, and better from that side because it was the highest.”
    —Henry David Thoreau (1817–1862)

    “The Forefathers’ day—Pilgrim day. We are at the same high call here today—freedom, freedom for all. We all know that is the essence of this contest.”
    —Rutherford Birchard Hayes (1822–1893)
