%X Using the temporal wavelet transform method for three-dimensional data,the temporal-spatial features and law of summer precipitation interannual variability over the Longitudinal Range-Gorge Region(LRGR) under effect of the summer monsoon are investigated.The results show that there are 2-year,7-year and 16-year characteristic timescales for the summer precipitation interannual variability over the LRGR under the effect of the summer monsoon.The larger amplitude energy regions corresponding to the 2-year,7-year and 16-year characteristic timescales are consistent with or normal to the mountain ranges of LRGR respectively.The summer precipitation longitudinal evolutions of the larger central latitude in association with the 2-year characteristic timescale show obviously longitudinal oscillations.But the summer precipitation longitudinal evolutions of the larger central latitudes in association with the 7-year and 16-year characteristic timescales have obviously the tendency to move towards the west and the east respectively.The summer precipitation latitudinal evolutions of the larger central longitude in association with the 2-year characteristic timescale also show obviously latitudinal oscillations.But the summer precipitation latitudinal evolutions of the larger central longitudes in association with the 7-year and 16-year characteristic timescales have obviously the tendency to move towards the north and the south respectively.
