Dust as a Potential Tracer for the Flow over Different Topographical Shapes Employing MODIS-Terra Observations

Joseph Barkan, Pinhas Alpert

Research output: Contribution to journalArticlepeer-review


The hypothesis, that the magnitude of the Froude number can represent the flow type around an obstacle was examined at several different topographical shapes in dust-laden environments. It was found that in most cases this hypothesis was true. Average of 16 May months AOT data extracted from the MODIS Terra satellite have shown that in case of Froude number less than one, the AOT isolines tend to follow the topographical contours of the mountain peak (the obstacle) along with a minimum AOT near the peak.
