Dear sir, while making the ".cli" files, i am getting "ALPHA" (WGEN parameter)values=0.000 for few months. further the weather being generated from the same .cli files, gives absured values for rainfall(for e.g. 2000mm in a single day) Kindly tell us that how the value for alpha is calculated? further we would like to know the equations/calculations/formulae that the model is using to generate the rainfall parameteres of .cli files. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
