Dr. Lewis (Lew) Gramer is an associate scientist at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML). His research involves a range of topics related to how ocean dynamics impact the rest of the natural world. In his current research, Dr. Gramer aims to better understand the interaction of coastal ocean downwelling and vertical ocean mixing with hurricane intensity and storm structure.

Current Work

Impacts of coastal ocean downwelling and vertical ocean mixing on hurricane intensity and storm structure.
