Automatic Tracking and Characterization of Cumulonimbus Clouds from FY-2C Geostationary Meteorological Satellite Images
Figure 7
Temporal evolution of cloud patch features for a Cb patch which is marked with a red star in Figure 3. (a) Minimum TB and mean TB ; (b) difference in TB over split windows (DSWT) and difference in TB over IR1 and WV (DIWT); (c) cloud area and perimeter; (d) displacement of geometric center and gravitational center; (e) eccentricity (ECCT), shape index of geometric momentum (SIGM), and shape index of the perimeter (SIP); (f) gradient of cloud TB (TOPG), boundary steepness (BS), and standard deviation (STD); (g) cloud life stages (L). L1, L2L8 means the same as in Figure 2; (h) cloud growth rate (CGR) and horizontal moving direction (HMDP); (i) vertical moving character of a Cb patch (VMCP) and horizontal moving speed (HMSP).
