Dynamically Constrained Nowcasting in the Coastal Ocean

Abstract

LONG-TERM GOALSOur long-term goal is to better understand ocean interactions at various space and time scales by quantifying submesoscale processes. We focus on the following four areas:•Understanding small-scale coastal ocean processes;• Understanding small-scale advective exchange and stirring;APPROACH 1We use a spectral technique called normal mode analysis (NMA), a generalization of a method first described by Rao and Schwab (1981) in an analysis of currents in Lake Ontario.

Elementary information in physics

“…The Shannon communication channel is intended to be set up between macroscopic systems, but effort is made to extend it to extremely simple systems, such as single atoms. 44,45 The present paper tries to discover the most elementary relations between the information and the physical processes. This work, being the first step in this field, treats the simplest physical scenes.…”
