Abstract:

Basing on the fax surface synoptic maps transmitted by Frei Meteorological Center, Antarctica, Chile, and 500hPa isobaric charts of southern hemisphere in the period of January, 1985 to October, 1987, drown by Beijing Meteorological Center, the heavy winds phenomena occurred over the Antarctic Peninsula and neighbouring area are studied. According to the relative locations of polar cyclones, Antarctic continental high and sub-tropical high, the weather situations producing heavy winds over this area are classified into four models: 1.strong polar cyclones; 2.strong sub-tropical high; 3.high centered on the southern America continent; 4.spreading southwardly of su-tropical high. The methoud of frocasting heavy winds in connection with the models over this areas are put forward.
