A typhoon usually develops from an unstructured cloud cluster. In general, the more axis-symmetry a typhoon cloud pattern is, the stronger the typhoon intensity could be. This study analyzes the MTSAT_IR1 image data of severe typhoon Jangmi during the period from tropical depression to severe typhoon stage. The gradient of the gray values in the MTSAT_IR1 image is calculated from the horizontal and vertical derivatives by using Sobel's template. Then, the deviation angle of each gradient vectordoi:10.7763/ijesd.2012.v3.219 fatcat:mnlkfvenjbbdrj6vufc42elcui
