Zusammenfassung |
To improve results in monthly rainfall
prediction, a parametrization of precipitation has been developed. The
thermodynamic energy equation used in the Adem thermodynamic model (ATM) and the
Clausius and Clapeyron equation, were used to obtain a linear parametrization of
the precipitation anomalies as a function of the surface temperature and the 700
mb temperature anomalies. The observed rainfall in Mexico over 36 months, from
January 1981 to December 1983, was compared with the results obtained of the
heat released by condensation, which is proportional to precipitation, using our
theoretical formula, and those obtained using a statistical formula, which was
derived for the ATM using 12 years of hemispheric real data. The verification
using our formula in Mexico, showed better results than the one using the
statistical formula.
