Abstract
Mazeika's method for forecasting mixed-layer (thermocline) depth
of the upper ocean layers is discussed along with a newer version of
this method developed by James. Using Mazeika's method primarily, a
verification for the Northeast Pacific Ocean was completed with data
from Ocean Weather Stations PAPA (50N, 145W) and NOVEMBER (30N, 140W)
and a point named MIDPOINT (40N, 140W) . The results indicate Mazeika's
method is successful at Station PAPA more than seventy-five percent of
the time during the heating season followed by a rapid decline as the
cooling season begins. The method should be useful in the entire
Central Subarctic Domain as described by John P. Tully. The method fails
at NOVEMBER and MIDPOINT producing less than thirty percent success in
prediction. James' version did not improve the results obtained at
Station NOVEMBER. This failure appears to be due to the controlling
parameters for processes in the Subtropic or Transitional oceanographic
regions (which include NOVEMBER and MIDPOINT); these differ from parameters
controlling oceanic processes in the Pacific Subarctic region
(Station PAPA) , which resemble those involved in the Atlantic region
for which Mazeika's method was developed.
Climatology data which can be used to obtain surface and 400-foot
level temperature are also tested. The results indicate these data are
very useful and accurate in determining the stability index required of
Mazeika's method.
