A study on the influence of sea breeze on line-of-sight links located in Visakhapatnam

Fading of microwave signal during the sea breeze circulation is observed over LOS links located in the Visakhapatnam region, operating at different frequencies and hop lengths. Atmospheric circulation due to the onset of sea breeze promotes the advection of water vapor around the propagation path, which brings about some distinct characteristic changes in the LOS link signal strength. The results indicate a distinct diurnal variations in respect of fading of LOS microwave links operating at Visakhapatnam.
