“…Clarifying the frequency of tropical cyclones in an era warmer than the present age would provide important information for predicting the frequency of tropical cyclones caused by global warming. Paleotempestology has sought to develop tropical cyclone activities over a large range of time scales, from daily to millennial-scale reconstructions (Muller et al, 2017). The more commonly used archives for past tropical cyclone activities include (1) historical documentary record, such as official histories, gazettes, newspaper, and civilian writings like travel logbooks, diaries, and poems (Fan & Liu, 2008); (2) speleothem (Frappier, 2008;Haig et al, 2014), coral-ring (Hetzinger et al, 2008;Kilbourne et al, 2011), tree ring archives (Miller et al, 2006;Li et al, 2011;Knapp et al, 2016;Trouet, Harley, & Domínguez-Delmás, 2016), and ostracoda (Lane et al, 2017;Lawrence et al, 2008); (3) beach ridges (Forsyth et al, 2010;Nott, 2011;Nott et al, 2009;Nott & Forsyth, 2012); and (4) coastal lacustrine, lagoonal, and marsh overwash deposits (Horton et al, 2009;Williams, 2012;Woodruff et al, 2009).…”
