Description:Utilizing error estimates of wind and temperature that are available from the National Meteorological Center optimum interpolation analysis technique, a Monte Carlo analysis is performed on the data of December 20, 1981 to provide error estimates of various energy budget calculations based on variance and co-variance elements. It is determined that the precision of estimates of integrated hemispheric energy parameters are on the order of 1%. For specific parameters, however, such as momentum transport, temperature variance etc., the calculated precision estimates can be quite variable in pressure and latitude. In regions where the parameter estimates are large and well defined, the standard deviations are better than 10%. Outside of these regions, however, where the values are small, the precision estimates become considerably worse and can be as large as 50-100%.
