Simulations of sea fog case impacted by air–sea interaction over South China Sea

Frontiers in Marine Science, 2022
A sea fog event in the South China Sea was simulated using a coupled ocean–atmosphere model (WRF for the atmosphere and ROMS for the ocean). Offshore and onshore visibility, liquid water content, air temperature, humidity, and wind speed observations and
