| Abstract | Instrumental records reveal that intense tropical cyclone (TC) activity varies with tropical sea surface temperature (SST) on annual-decadal scales. Drivers of intense TC activity at the
centennial-millennial scale are less clear, due to the sparseness of pre-observational reconstructions. Here, we present a new 2 kyr continuous activity record of intense TCs from offshore eastern China. Our reconstruction indicates that this site
witnessed enhanced TC activity during relatively warm periods, with a widespread increase in TC activity during the later part of the Little Ice Age. This latter observation reveals that enhanced TC activity was synchronized with increased Asian dust
emissions during the Little Ice Age. TC activity was also lower in the late Roman Warm Period, when SST was higher but Asian dust emissions were lower than in the early phase. Such patterns suggest a centennial-millennial link between TC climatology
and a combination of SST changes and Asian dust levels. |
| Summary | (Plain Language Summary, not published)
Availability of dust in the atmosphere enhances the intensity of tropical cyclones in the West Pacific Ocean. This paper presents a 2000 year record of
cyclone intensity and dust generation in China. A similar effect has been suggested for the Atlantic Ocean and increased desertification with global warming may result in more intense hurricanes impacting eastern Canada. |
