Some Long-Term Relations Between Equatorial Sea-Surface Temperature, the Four Centers of Action and 700 mb Flow.

摘要: Abstract The relation between sea-surface temperature (SST) in the eastern equatorial Pacific (0°–10°S, 180°–;80°W), and surface pressure, latitude longitude of four centers action (Icelandic Aleutian Lows, Atlantic Highs), has been examined based on seasonal data from 1899 through 1978. this SST indexes 700 mb zonal flow 1949 1983. Warm associated, a significant fashion, with stronger than average westerly winds at 20–35°N band, weaker 35–55°N below-average central pressure High, High Low, southward displacement Icelandic eastward High. only evidence precursor to warm (El Nino) is relatively small distance Low two seasons before warme...
