The purpose of the present study is to find out that within the sigma coordinate system, any difference exists in two formulations of the equations referred to as model. A based on the conservation of total energy and lower order moments of potential enthalpy and model B based on the conservation of total energy and perturbation energy around a given arbitrary stratification. Both the models yielded forecasts close to each other which leads to conclude that thus lack of sensitivity of the model formulation may be due to lack of precision in the data and, therefore, needs performing of similar experiments on a wide set of FGGE data sets.
