(a) The frequency of RI, NI, and SI in four outflow directions. The number of the below direction is the total number of the cases for each single outflow direction. (b) The average intensification rate for 12 hr of the four outflow directions in each single outflow strength bin (m s−1). NW, NE, SE, SW is northwest, northeast, southeast, and southwest, respectively.
