formed and moved in conjunction with lower-tropospheric eyewall mesovortices, and accounted for a large portion of the total upward mass flux. Similarly, Braun and Wu (2007) in an investigation of the inner-core structure of Hurricane Erin (2001) concluded that the organization of eyewall vertical motion was influenced strongly by the strength of the vertical wind shear, with relatively weak shear (<5 m s −1 ) allowing mesovortices (and associated convective updrafts) to form on all sides of the
