October is a month of transition for weather patterns over the Arabian Sea. In the summer, winds blow from the sea toward land. In the winter, the winds reverse and blow over the Arabian Sea from the northeast. During October, between the summer and winter monsoons, the prevailing wind direction varies.
When the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP satellite acquired this image on October 26, 2016, northeasterly winds were dominant and blew several dust plumes off the coast of Iran and Pakistan. VIIRS captured additional images of dust over the Arabian Sea on October 25 and October 27.
