Description
Summary:The global operational oceanography services provide freely accessible wave data. This research aims to use ERAS and CMEMS reanalysis to study the characteristics of the height, period, and direction of waves in the Java Sea. Such wave information plays an important role in coastal protection, shipping safety, and fishing activities on the northern coast of Java. The datasets are analyzed from 1993-2019 to obtain the extreme wave height, variability in wave height and direction, also wave propagation. An extreme wave height of 1.6 meters was obtained at the 95th percentile, and an extreme wave height of more than 3 meters was obtained during the 100-year statistical return period. The height and direction of the waves follow the seasonal wind variability. Wave mainly comes from the west during the northeast monsoon and in the reverse direction during the southeast monsoon. Swell propagation is detected from the two-dimensional spectrum. The primary swell comes from the South China Sea, but the Indian Ocean swell also enters the sea off West Java through the Sunda Strait.
