The Characteristic Analysis of Rainfall and Temperature between 1956 and 2013 in the Hanjiang River Basin
Abstract: In order to evaluate the characteristics and change trend of the surface precipitation and temperature in the middle and lower reaches of the Hanjiang River before the working of the middle route of the South-to- North Water Diversion Project, eighteen meteorological stations were selected. Furthermore, mathematical statistics, Mann-Kendall test and Spearman test were used, and two aspects of temperature and runoff were analyzed based on the meteorological data of the selected stations. The results are as follows. 1) The surface precipitation of the upper drainage area of Hanjiang River basin is 158 mm more than that of the lower drainage area; the temperature of the whole basin has been raised since 1990. 2) After trend analysis, it unfolds that the change trends of the rain-time series in this region are not noticeable, but the temperature shows a significant rise. 3) The imbalance between water supply and demand in the lower Hanjiang River basin will be very conspicuous, if there are not any engineering and non-engineering actions to take.
