Re: Brief Thoughts on Irene

According to NOAA "Shear - Variation in wind speed (see speed shear) and/or direction (see directional shear) over a short distance. Shear usually refers to vertical wind shear, i.e., the change in wind with height, but the term also is used in Doppler radar to describe changes in radial velocity over short horizontal distances. "
