TIME: Time when dropwindsondes reached the surface. (UTC)
DIST: The distance form each dropwindsonde to the corresponded storm center. (km)
WD: Surface wind direction. (degree)
Surface wind speed: (unit : m/s)
(1) WS: Surface wind speed (at a height of 10 meters) directly from the dropwindsondes.
(2) MBL (Franklin 2003): Averaging the dropwindsonde wind speed over the 0~500 m layer, multiplied by 0.80.
(3) WL150 (Franklin 2003): Averaging the dropwindsonde wind speed over the 0~150 m layer, divided by 1.229.
