Abstract

As an important maritime hub, Bohai Sea Bay provides great convenience for shipping and suffers from sea ice disasters of different severity every winter, which greatly affects the socio-economic and development of the region. Therefore, this paper uses FY-4A (a weather satellite) data to study sea ice in the Bohai Sea. After processing the data for land removal and cloud detection, it combines multi-channel threshold method and adaptive threshold algorithm to realize the recognition of Bohai Sea ice under clear sky conditions. The random forests classification algorithm is introduced in sea ice identification, which can achieve a certain effect of sea ice classification recognition under cloud cover. Under non-clear sky conditions, the results of Bohai Sea ice identification based on random forests have been improved, and the algorithm can effectively identify Bohai Sea Ice and can improve the accuracy of sea ice identification, which lays a foundation for the accuracy and stability of sea ice identification. It realizes sea ice identification in the Bohai Sea and provides data support and algorithm support for marine climate forecasting related departments.
