| Résumé | (disponible en anglais seulement)
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. |
| Sommaire | (Résumé en langage clair et simple, non publié)
La présence de poussière dans l'atmosphère augmente l'intensité des cyclones tropicaux dans l'ouest de l'océan Pacifique. Cet article présente
un record de 2000 ans d'intensité de cyclone et de génération de poussière en Chine. Un effet similaire a été suggéré pour l'océan Atlantique et l'augmentation de la désertification avec le réchauffement climatique pourrait entraîner des ouragans
plus intenses dans l'est du Canada. |
