Wave climate change analysis based on long time-series buoy data

Abstract

Using the buoy dataset from 2011 to 2022, the trend of wave climate change was analyzed at DaChen station located in the Taizhou City, Zhejiang Province. The results show a decreasing trend of the maximum significant wave height (Hs). Whereas the wave height is higher than 4 m, the corresponding wave period is in the range of 8-14s. Disastrous waves mainly occur between July and October. The relevant analysis presents the wave characteristics at the DaChen station, which is helpful for protecting the life safety along the coast and providing references for offshore engineering design.
