A COMPARISON OF TOTAL PRECIPITATION VALUES ESTIMATED FROM MEASUREMENTS AND A 1D CLOUD MODEL

The purpose of this study is to establish a relation between observed total precipitation values and estimations from a one-dimensional diag nostic cloud model. Total precipitation values estimated from maximum liquid water content, maximum vertical velocity, cloud top height, and temperature excess are also used to provide an equation for the total precipitation prediction. Data for this study were collected in Istan bul during the autumns of 1987 and 1988. The statistical models are de veloped with multiple regression technique and then comparatively veri fied with independent data for 1990. The multiple regression coefficie nts are in the range of 75% to 80% in the statistical models. Results of the test showed that total precipitation values estimated from the above techniques are in good agreement, with correlation coefficient b etween 40% and 46% based on test data for 1990.
