Four time differencing schemes were tested using a
barotropic primitive equation model on a spherical
staggered grid with an analytic input in order to compare
amplitudes, phase speeds, and computation time for
each. The methods tested were the leapfrog, Euler-backward,
leapfrog-trapezoidal , and Adams-Bashford. One
set of experiments was performed using an averaging
technique to reduce the effects of gravity waves in the
higher latitudes. Another set was performed without the
averaging in order to determine the effects of this
technique on the solutions.
