Dual-aircraft investigation of the inner core of Hurricane Norbert. Part I: kinematic structure

Abstract

The wind field was asymmetric, and the asymmetry varied with altitude. As altitude increased the location of the maximum tangential wind sloped upwind, from left of the storm track at 1km altitude to right of the storm track avove 3km. The radial wind at 1km altitude was inward in front of the storm and outward behind. This pattern in the radial flow reversed above 3km altitude, with inflow at the rear of the storm and outflow in the front. The maximum vertical velocity was located to the left of the storm track at all levels. This maximum sloped downwind, increasing in altitude from 2km in front of and to the left of the track to 8km behind and to the right of the track. -from Authors
