can be added to the Cook Plant plume.
These winds, when blowing from the southwest quadrant (south to west), push
water against the shore where it is deflected to become a northward alongshore
current, when these winds are from the northwest quadrant (west to north) the
water they push slides along shore as a southward alongshore current.
Typically the situation off the Cook Plant site indicates an alongshore current of greater or less strength running either northward or southward. To be
added to this condition are movement components of the warm plume water that result from direct wind pressure on the floating warm water.
The shoreline along the Cook Plant site is roughly NNE-SSW (23~ - 203~ to
our best estimate). The relations of this shoreline trend to the directions of
winter winds are significant in deciding the directions and importances of winter
wind-induced components of plume direction.
Figure 21 is a modification of Figure 2.2-19 of the FSAR. This figure is a
wind-rose depicting the time frequency distribution of winds from different directions during the winter. In the center of this wind-rose (in the space customarily reserved for the calms of wind) we have drawn the trend of the shore and
shaded the landward side. The basic figure 2.2-19 is from Smith-Singer Inc.,
meteorological consultants to Indiana and Michigan Electric Company, to whom our
thanks are rendered.
On the whole, winter winds from the northeast and southeast quadrants are
from the land. What little wind-induced components of plume direction they produce are directed away from the shore.
Winds from north-northeast or south-southwest are essentially parallel to
shore, and the components of plume-direction that they induce are also parallel
to shore where they either reinforce or oppose the alongshore currents.
Winds from the southwest quadrant (those from between 190~ and 210~ are
most frequent) produce wind-induced components nearly parallel to shore. Wind31
