Western Iran is an important dust source region in Middle East, with strong activities occurring springtime. Based on a three-hourly meteorological station data, remarkable decadal change of frequency the spring season has been found west and southwest Iran, less during 1992–2005 (hereafter as “P1”) more frequent 2006–2015 “P2”). The signal closely associated corresponding difference precipitat...
