Abstract

As ENSO (El Nino-Southern Oscillation) often leads to alteration in atmospheric circulation and further causes climatic variation, exploring the relationship between regional climate changes and ENSO is helpful for understanding the variation in regional hydrology. This study analyzed the relationship between the climate changes in the Jinghe watershed and ENSO through Mann-Kendall, correlation test and wavelet analysis. Results showed that climate tended to be warmer and drier during 1960-2005, and this trend has been more significant since the 1990s. Climate changes in the Jinghe watershed were closely correlated with ENSO. Precipitation was more sensitive to ENSO than temperature. Precipitation was more sensitive to SOI and temperature was more sensitive to SST. The impacts of ENSO warm events on climate changes in the Jinghe watershed were more significant than cold events.
