From: Anomalously weak intensity of tropical cyclones striking eastern China over the past two millennia

Comparison (a) and correlation (b) of the sand content of core ZM01 with the instrumental TC wind speed (TCI_ws) affecting the Zhejiang coast (1984–2018 CE). The empirical relationships (c) between D90 and relative distance for P1 and P2 sections, and (d) between D90 and transport distance for TC-event-beds in core SA, both on the Jiangsu tidal flats.
