| Abstract: | Using the observational air and surface temperature datasets of 112 stations in the Tibetan Plateau(TP) and around areas,the temporal-spatial evolution characteristics of the difference of temperature between surface and atmosphere(Ts-Ta) over Tibetan Plateau in the early stage of East Asian Summer Monsoon(EASM) onset and its connections with the EASM are analyzed by EOF(Empirical Orthogonal Function),REOF(Rotated Empirical Orthogonal Function),and other methods.The results show that,the time when Ts-Ta in ... |
