The AA. examine the altitude dependence of trends of daily climate extremes in southwestern China between 1961 and 2008. A total of 12 indices of temperature extremes and 11 indices of precipitation extremes at 111 stations in southwestern China at altitudes of 285-4700 m were examined. Significant correlations of temperature extremes and elevation included the trends of diurnal temperature range, frost days, ice days, cold night frequency and cold day frequency. Regional trends of growing season length, warm night frequency, coldest night and warmest night displayed a statistically significant positive correlation with altitude. These characteristics indicated the obvious warming with altitude. The analysis therefore revealed an enhanced sensitivity of climate extremes to elevation in southwestern China in the context of recent warming
