Tropical Cyclone Center Locating based on Satellite Cloud Images
Tr Tropical Cyclone (TC) center locating is a pical crucial step in analyzing TCs. TCs can be divided into Eye TC and No No-eye TC. Different TCs have different characters. Before locating its center, TC should be detected from the whole satellite cloud image. Both infrared (IR) images and visible (VIS) images are used to detect TC. Some pattern recognition and image processing methods are applied in the paper. They are well used both in detecting TCs and getting the centers of Eye TCs. Gray ray Model and Chan odel Chan-Vese model play important roles in locating the No No-eye TCs TCs’’ centers. Gray Model is odel used to predict the initial position of the next TC center center. Since the cloud wall near the No No-eye TC center is homocentric circle, Chan Chan-Vese model (C C-V mod model) is used to get TC contour. el) Experiments on MAN MAN-YI (in 2007) and WUTIP (in 2007) show that the average error is within 0.2 degrees compared with the best track data supported by China Meteorological Administration Administration.
