✦ Synopsis

Statistical series of flood/drought (F/D) grades and F/D variabilities were derived for the flood and drought chronology (2700 BC-1980 AD) of central China. Two types of climatic jumps were analyzed. The moving sign-test, T-test and F-test were applied to detect jump signals. A few wet-to-dry jumps for timescales from decades to thousand years were compared with relevant climatic changes in other regions of the world. Changes in the annual rainfall due to jumps were estimated. Some F/D-deficient-to-F/D-frequent jumps were also found and their significance is discussed.
