Abstract

Abstract:

Based on the data for daily rainfall in summer at 102 meteorological stations in the arid region of northwest China and the monthly ERA5 atmospheric circulation reanalysis data for 1961—2022, the interdecadal changes in the dominant modes of summer rainfall anomaly in the arid region of northwest China and the associated circulations of these modes are investigated. The results show that: (1) The summer rainfall in the arid region of northwest China exhibits obvious interdecadal variation, which can be divided into two periods: the dry period (1961—1986) and the wet period (1987—2022). During the wet period, the increase in rainfall in the Tarim Basin is attributed to an increase in the number of rainfall days and the rainfall intensity, especially the increase in the number of rainfall days, which is more than 2 d, whereas it is attributed to an increase in rainfall intensity in the rest of the region. (2) The dominant modes of summer rainfall in the arid region of northwest China during the dry period are the northern Xinjiang type, the Tarim Basin type, and the Hexi-Alagxa type, whereas during the wet period, the dominant modes of summer rainfall are the northern Xinjiang type, the Hexi-Alagxa type and the western Tarim Basin type. (3) There are obvious differences in the circulations of the same rainfall type over different interdecadal periods, and such differences in circulations are mainly reflected in the movement of the subtropical westerly jet, the structures of the Central Asian cyclone and the Mongolian anticyclone (cyclone), and changes in the source and path of water vapor transport.

Key words: summer rainfall anomaly, interdecadal change, dominant modes, associated circulations, arid region of northwest China
