| Abstract | Frequency changes in intense typhoons are of great concern to modern society. However, current understanding of the influence of climate on typhoon activity on the millennial scale is restricted by the
sparseness of preobservational reconstructions in the north-western Pacific. This study presents a 5500 year long typhoon record from the Jiangsu coast that provides the first >2 ka record in eastern China. Variations in the D90 grain size are the
best predictor of recent typhoons in a second short high-resolution core. Comparison with other typhoon records from south-eastern China establishes a China millennial typhoon variability index during the middle to late Holocene, with maxima at ca
4750 +/- 170, 3500 +/- 220, 1500 +/- 480 and 250 +/- 170 yr BP and minima at ca 5200 +/- 300, 4150 +/- 430, 2600 +/- 650 and 750 +/- 270 yr BP. Peaks in typhoon activity in south-eastern China (compared with Japan) correlate with damped (enhanced) El
Ni~no-Southern Oscillation and weak (strong) East Asian Summer Monsoon, indicating a seesaw pattern in typhoon activity between the two regions. A shift in typhoon frequency pattern was also identified around 2000 yr BP in south-eastern China, with
subsequent more frequent typhoon activity. At that time there was sustained Atlantic Meridional Overturning Circulation reduction and its associated El Ni~no-Southern Oscillation enhancement, so Atlantic Meridional Overturning Circulation-driven El
Ni~no-Southern Oscillation changes are likely to be the major cause of the significant increase in typhoon activity since 2000 yr BP, resulting in the 1500 +/- 480 and 250 +/- 170 yr BP China millennial typhoon variability peaks. To accurately
predict changes in intense typhoon activity, it is therefore important to understand how the Atlantic Meridional Overturning Circulation and El Ni~no-Southern Oscillation will respond to future climate change. |
| Summary | (Plain Language Summary, not published)
This study compares millenial-scale cyclicity over the past 5,000 years of hurricanes or typhoons in the North Atlantic Ocean and the North Pacific
Ocean. Early global warming 2500 years ago caused a change in the periodicity and forcing mechanisms of these storms. |
