Effect of North Atlantic Oscillation on water vapor transport over the Tibetan Plateau in winter
Based on the ERA-Interim reanalysis data from 1979 to 2014,the water vapor distribution and transport characteristics of the Tibetan Plateau(TP)in winter are analyzed,and the influence of the North Atlantic Oscillation(NAO)on the winter water vapor transport over the TP is discussed.The results show that the distribution characteristics of water vapor in the main part of the plateau in winter are wet in the south and dry in the north,and the water vapor transport in the eastern and western boundaries of the main region of the plateau is closely related to the NAO,and the NAO index is positively correlated with the western boundary,negatively correlated with the eastern border.The influence of NAO on water vapor transport in the plateau boundary area is stronger than that in the main region of the plateau.Especially for the southwestern and southeastern of the TP,NAO has a significant correlation with the water vapor transport at the four boundaries of these two regions.
