The Limiting Factors for the Regions of Wind Direction and Speed in Nineveh Governorate

The research aims at standing on the most effective factors in the direction and speed of wind in Nineveh Governorate and that this query resulted from many reasons some of them are related with the district study area and another with the site of stations of climate factors measuring.
