    Abstract
  • Based on the Regional Spectral Model (RSM) re-analysis data from Japan Meteorological Agency (JMA) with a horizontal resolution of 20 km and a time interval of 6 h, this study works on the outer and inner core size of 2174 samples of tropical cyclones (TCs) occurring over the western North Pacific between 2001 and 2007. Some conclusions have been drawn on the basis of preliminary analysis of the TC inner core size and outer size and their relationship with TC intensity. First, the outer size increase (decrease) helps TCs intensify (weaken). Second, the enlargement (shrinking) of the inner core size helps TCs intensify (weaken) if TCs have a large inner core (with radius of maximum winds larger than 120 km). Contrarily, when TCs have small inner core (with radius of maximum winds smaller than 120 km), the enlargement (shrinking) of the inner core is good for weakening (intensifying) of TCs.
