A two-level numerical prediction model incorporating
terrain and non-adiabatic warming effects is tested. An
attempt is made to determine the empirical coef ficient (s)
for each of three terms composing a prognostic equation
designed to predict the 1000 to 500-mb thickness through
the use of a digital computer.
The model is applied to three cases in April for a
large part of the Northern Hemisphere. The predicted
positions of most of the pressure systems were reasonablyaccurate;
however the model tends to over-develop pressure
centers. The effects of terrain and non-adiabatic warming
were in accord with theoretical expectations; however, the
excessive development dominated the numerical verification
so that no significant improvement resulted from the inclusion
of these refinements.http://www.archive.org/details/numericalmethodo00chinRepublic of China NavyRepublic of Korea NavyApproved for public release; distribution is unlimited
