Distinct linkage between winter Tibetan Plateau snow depth and early summer Philippine Sea anomalous anticyclone

Abstract

This article demonstrates that the above-normal Tibetan Plateau snow depth (TPSD) in winter appears to be followed by an intensified Philippine Sea anticyclone in June (PSAC-J), and vice versa. This linkage is clearly independent of the relationship between the El Niño-Southern Oscillation (ENSO) and the PSAC-J. Moreover, winter TPSD anomalies are typically associated with a PSAC-J pattern that shifts northwards compared with that associated with ENSO. A better understanding of the combined effects of the winter TPSD and ENSO on the PSAC-J could improve our ability to predict both the East Asia summer monsoon and variations in the Meiyu-Changma-Baiu rainbelt.
