Rahdomly Oriented ndimensiional Waves produce
An isotropic corre;ation that resembles empirical corelaion of clouds
Heavy rainfalland500mb hts The correlation functions although simple in
form have proven toprovide non singular prediction correlation matrices
although this was expected since the forms are derived from realizations albeit virtual realizations
Given the correlations between ob locations and also ddsired predicted sites,
Multiple linear regression can calculate values at desired points for example a regular grifor input to NWP Further sine the regression provds a measure of uncertainty the estimate are in fact a distribution allowing for a plausible varity of initial conditions suitable for ensemble forecasts
