Abstract

The precipitation regime of the low latitude highlands of Yunnan is subject to the interactions between the East Asian Summer Monsoon and the Indian Summer Monsoon, and the influence of surface orography. An understanding of changes in its spatial and temporal patterns is urgently needed for climate change projection, hydrological impact modelling, and regional and downstream water resources management. Using daily precipitation records of the low latitude highlands over the last decades (1950–2007), a time series of precipitation indices was constructed. The Trend-Free Pre-Whitening Mann-Kendall trend test was then used. The results show that there is no significant trend in annual precipitation and strong seasonal differentiation of precipitation trends across the low latitude highlands. Springs and winters are getting wetter and summers are getting drier. Autumns are getting drier in the east and wetter in the west. As a consequence, the seasonality of precipitation is weakening slightly. Additionally, regional differentiation of precipitation trends is remarkable
