Research on Evaporation Duct Height Prediction Modeling in the Yellow and Bohai Seas Using BLA-EDH

Atmosphere
Evaporation Duct Height (EDH) is a crucial parameter in evaporation duct modeling, as it directly influences the strength of the waveguide trapping effect and significantly impacts the over-the-horizon detection performance of maritime radars. To address
