“…This sequence is consistent with that proposed by Yi et al [20], whereby the parent cell provides the dynamical background for the development of the child cell in the feeder-type cells merging process. 3 , which is the sum of all the individual small ions and charged hydrometeors in merging process), flow field (vector arrows in m/s, superimposed horizontal and vertical wind speeds), echo intensity (black isopleths are CR, with values of 30, 36, 42, 48, 54, 60, and 66 dBZ from the outside to the inside, respectively), and the isotherms distribution (black dashed lines are 0, −10, −20, and −40 • C from bottom to top, respectively) along the profile where the black profile line is located at the corresponding moment in Figure 3.
