Impact of Typhoon on Evaporation Duct in the Northwest Pacific Ocean
IEEE Access, 2019 Evaporation duct is a layer above the ocean surface due to the inherent humidity inversion at the air-sea boundary layer. The formation of the duct depends on meteorological factors near the ocean surface and is affected by weather process above the ...

Research on evaporation duct height prediction based on back propagation neural network [PDF]
IET Microwaves, Antennas & Propagation, 2020 Evaporation duct is an abnormal refraction atmospheric stratification frequently appearing at sea. Accurately obtaining evaporation duct height (EDH) is significant for the effective application of electromagnetic system equipment. To overcome the limitations of theoretical prediction models, this study proposes a pure data‐driven back propagation ...

RETRIEVING EVAPORATION DUCT HEIGHTS FROM POWER OF GROUND-BASED GPS OCCULTATION SIGNAL [PDF]
Progress In Electromagnetics Research M, 2013 Evaporation duct is a manifest phenomenon that can afiect microwave propagation seriously with low elevation angles near the sea surface. As an important parameter to describe the characteristic of the evaporation duct, duct height can be estimated from radar sea echo using a technique called as \refractivity from clutter". In this study, we proposed a
