Abstract: In this communication we have studied the environmental changes in the Pakistan coastal water. Evaporation Duct is the continuous phenomena and occurs due to climatic changes in the region. It is generally observed that atmospheric occurrences have great impact on radio waves communication over the sea and especially in coastal waters. These climatic variations are also the main reason for the formation of evaporation duct in Pakistan Coastal water. The height of the duct varied according to the weather phenomenon. In this study we selected four different positions to take the observations in the formation evaporation duct and propagation of radio wave through these ducts. The data are collected from National Institute of Oceanography (NIO) and plotted as the time series profiles of potential temperature, pressure and humidity cause the refractive index of the air in this region. They are of particular importance at the extreme limits of propagation and allow the radio waves to propagate beyond the horizon. It is important to claim that this research work can be profitable for the better and affective utilization of ground waves communication path in Pakistan coastal water.
