| 英文摘要 | Lightning data from the world wide lightning location network along with tropical cyclone (tc) track and intensity data from the china meteorological administration are used to study lightning activity in tcs over the northwest pacific from 2005 to 2009 and to investigate the relationship between inner core lightning and tc intensity changes. lightning in tcs over the northwest pacific is more likely to occur in weak storms at tropical depression (10.8-17.1ms(-1)) and tropical storm (17.2-24.4ms(-1)) intensity levels, in agreement with past studies of atlantic hurricanes. the greatest lightning density (ld) in the inner core appears in storms undergoing an intensity change of 15-25ms(-1) during the next 24h. lightning is observed in all storm intensity change categories: rapid intensification (ri), average intensity change (aic), and rapid weakening (rw). the differences in ld between ri and rw are largest in the inner core, and the ld for ri cases is larger than for rw cases in the inner core (0-100km). lightning activity there, rather than in the outer rainbands, may be a better indicator for ri prediction in northwest pacific storms. there was a marked increase in the lightning density of inner core during the ri stage for super typhoon rammasun (2008). satellite data for this storm show that the ri stage had the highest cloud top height and coldest cloud top temperatures, with all the minimum black body temperature values being below 200k in the inner core. |
