LONG TERM GOALS. The goal of this research is to gain a
better understanding of the flow characteristics of the
marine surface layers, including the coupling at the air-
sea interface. Specifically, the research focuses on the
influence of ocean waves on turbulent processes,
especially those involved in stress-wave interactions.
The long range goal of this research is to develop new
and/or revise old theoretical descriptions of turbulence,
such that they are universally applicable to both over
land and over sea boundary layers. This is to be
accomplished by focusing on the physical processes unique
to the marine boundary layers through a combination of
scale analysis and numerical modeling. OBJECTIVES. The PI
s first objective is to improve our understanding of flux
profile relationships over the ocean using our profile
measurements in the kinetic energy, momentum, and scalar
variance budget equations. This involves an investigation
of the applicability of Monin-Obukhov (MO) similarity
theory to over-ocean measurement in order to determine
these functions and their proportionality factors (e.g.,
the von Karman and Kolmogorov constants). That is, the
goal is to determine these functions over the open ocean
where a difference with land derived functions is
possible due to the fluid ocean surface. The PI s second
objective in this research is to investigate how the wave
induced flow affects the turbulent processes in the
marine surface layer. In these studies the PI will focus
on the role that stress/wave interaction plays in
modifying the magnitude and direction of the momentum
flux within the wave boundary layer (WBL).
