Investigation and comparison of sea breeze, land breeze and systematic wind effects on Persian Gulf north coast's wind pattern

Results show that the Persian Gulf's coastline structures and features (e.g. mountains) play key roles in determining wind characteristics in northern side of the Persian Gulf. By advancing from west to east part of the Persian Gulf, general wind pattern is controlled by various wind components (systematic or land-sea breeze components). While, systematic wind are govern in western head's wind structure, land-sea breeze play a key role for determining wind features in the eastern sections, where systematic component is impact inconsiderable. Decreasing of mountains distance from beach in eastern rather (Daier station to Bandar Abbas) than western coasts (Abadan station to Daier) is main reasons to decrease the systematic wind energy by its friction with mountains. The land-sea breeze effects on local wind structures increase due to positive impact of mountains that intensified it in eastern parts. In the other hand, land and sea breezes influence intensify when systematic wind is calm. Land and sea breezes speed decrease slightly about 2ms-1 to 3ms-1 from west to the east. Through the seasonal analysis, it is deduced that summer's sea breeze is more intense and the possibility of its occurrence is much more frequently than other seasons. Also it is more sharply rather than land breeze during all seasons. Since nighttime is longer than daytime, land breeze occurred more than sea breeze with less speed values during winter.
