| Abstract: | Four models used for evaluating the height of the evaporation duct from measured atmospheric pressure, water and air temperatures, and air humidity are considered.The calculated results are compared with the duct heights measured during two oceanographic expeditions in the tropical zone of the Atlantic Ocean and the equatorial zone of the Indian Ocean. The sensitivity of models to the errors in the meteorological parameters is investigated. It is shown that, in the case of unstable stratification, the heights of ducts in the 5–20-m range can be evaluated with an error of about 2.5 m. Recommendations for selection of optimal models are given. |
