DRY/WET CLIMATE CHANGE SINCE 960 A. D.IN TAIHU DRAINAGE BASIN OF CHINA

  • The present study reconstructs an annual dry/wet grade series from 960 A. D. to 1992 A. D. in the Taihu drainage basin of eastern coast, China by collecting historical climatic records, to examine the climate periodicity and climate jumps. Power Spectrum analysis reveals that the dry/wet climate in the study area was a superposed phenomenon with the major period of quasi-100-year, and several other notable periods. These periods were supposed to be closely linked with the celestial activity. Climate junps are detected using moving t-test. The two abrupt changes around 1247-1263 A. D. and 1618-1635 A. D. are proved as regional events. The 14th to 15th century appeared as the wettest period during the last 1000 years in the Taihu drainage basin. These are interpreted as the consequence of east Asia climate change.

Abstract: The present study reconstructs an annual dry/wet grade series from 960 A. D. to 1992 A. D. in the Taihu drainage basin of eastern coast, China by collecting historical climatic records, to examine the climate periodicity and climate jumps. Power Spectrum analysis reveals that the dry/wet climate in the study area was a superposed phenomenon with the major period of quasi-100-year, and several other notable periods. These periods were supposed to be closely linked with the celestial activity. Climate junps are detected using moving t-test. The two abrupt changes around 1247-1263 A. D. and 1618-1635 A. D. are proved as regional events. The 14th to 15th century appeared as the wettest period during the last 1000 years in the Taihu drainage basin. These are interpreted as the consequence of east Asia climate change.
