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.
