Title: EFFECTS OF AN ATMOSPHERIC COLD SOURCE OVER TIBETAN PLATEAU ON QUASI 4-YEAR OSCILLATION OF OCEAN-ATMOSPHERIC-LAND INTERACTIONS
Abstract: Using correlation analyses, composite analyses and singular value decomposition, this paper discusses the relationship between an atmospheric cold source over eastern Tibetan Plateau (TP) and atmospheric / ocean circulation. In winter the anomalously strong (weak) atmospheric cold source over eastern TP results in the fact that from spring to autumn low-level anomalously north (south) winds appear in eastern China and low-level anomalously zonal west (east) winds prevail in equatorial Pacific. This helps the occurrences of anomalously warm (cold) sea surface temperature in the subsequent autumn and winter. And the anomalous variation of sea surface temperature over the equatorial middle and eastern Pacific in winter can influence the snow depth and intensity of the cold source over TP in the following winter via the variation of the summertime west Pacific subtropical high (WPSH).
