Tasks of the Harbors Model Enhancement Program 
Objective 
This report is the second in Task B.4, “Wind-Driven Circulation 
Analysis," of the Model Enhancement Program. The first report (Smith 1989) 
examined a prototype data set gathered in the harbors by the National Oceanic 
and Atmospheric Administration in the summer of 1983. That data set 
consisted of tidal current measurements, tidal elevations, and local wind 
measurements. The present report will summarize winds over the harbors and 
examine, with the aid of a calibrated numerical model, the effects of various 
wind conditions on circulation throughout the harbors. 
Chapter 2 discusses typical wind conditions, Chapter 3 describes selection 
of test conditions, Chapter 4 presents the numerical hydrodynamic model 
applied in this study, Chapter 5 examines tests and analysis performed, and 
Chapter 6 presents conclusions. For convenience, the abbreviations LA and 
LB will be used throughout this report to indicate Los Angeles and Long 
Beach, respectively.
