Feasibility analysis of early warning of sea fog within six hours for two harbors in the South China Sea

Frontiers in Earth Science, 2022
Sea fog significantly impacts harbor operations, at times even causing navigation to cease. This study examines two harbors in the north of the South China Sea, analyzing the feasibility of increasing each harbor’s sea fog early warning capability to 6 h
