Precursory Signals (SST and Soil Moisture) of Summer Surface Temperature Anomalies over the Tibetan Plateau

Understanding the variability of surface air temperature (SAT) over Tibetan Plateau (TP) and its precursory signals is great benefit to climate change adaptation socioeconomic development. This study explores summer SATs TP in oceanic land boundary conditions. The results show that eastern SAT significantly correlated with three precursors April: high-latitude North Atlantic sea (SST), northern Indian Ocean SST, soil moisture (SM). April SST anomalies (SSTAs) can exert a cross-season impact on through two processes. SSTAs maintain from modulate atmospheric circulation exciting downstream wave train during summer, finally TP. In addition above process, may remotely regulate simultaneous SM subcontinent stimulating pattern. Through persistent SM–precipitation interaction, anomaly affect local precipitation associated condensation heating ensuing which forces an anomalous cyclone–anticyclone pattern around accordingly affects Additionally, persist adjust intensity location western Pacific subtropical high Kelvin-wave-induced Ekman divergence eventually affecting SAT. signals, synergistically contribute SAT, be applied predicting
