Study on the relativities of the tropospheric microwave trans-horizon propagation above ocean surface and the marine atmospheric environment characteristics has important significance for the short-term prediction of the trans-horizon propagation and for the designs and the applications of the radio-communication systems. In this paper, based on the transmission loss data collected in the oversea experiment at 14.1 GHz on the area of Yellow Sea and Bohai Sea of China and the synchronous meteorological data collected from the meteorology grads tower which founded in the transmitter station, the relativities of the transmission loss and the evaporation duct height are analyzed with wind direction, wind speed and the difference of air temperature and sea temperature, respectively. The usability of the coastal meteorological data for the tropospheric microwave trans-horizon propagation is studied, and the results are validated with the parabolic equation method and the Advance Refractive Effects Prediction System (AREPS). The conclusions are helpful for the study of the propagation characteristic and the short-term prediction of the tropospheric microwave trans-horizon propagation above ocean surface.
