摘      要：We use FLIGHT+ aircraft reconnaissance data for tropical cyclones(TCs) in the North Atlantic and Eastern Pacific from 1997 to 2015 to re-examine TC fullness(TCF) characteristics at the flight *** results show a strong positive correlation between the flight-level TCF and the intensity of TCs,with the flight-level TCF increasing much more rapidly than the near-surface TCF with increasing intensity of the *** tangential wind in small-TCF hurricanes is statistically significantly stronger near the eye center than that in large-TCF ***-TCF hurricanes have a ring-like vorticity *** significant correlation is observed between the flight-level TCF and the comparative extent of the vorticityskirt region occupied in the outer core *** proportion of the rapid filamentation zone in the outer core skirt increases with increasing flight-level *** differences in entropy between the radius of the maximum wind and the outer boundary of the outer core skirt also increase with increasing flight-level TCF.
