This book was released on 1989 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using forecast relative humidity (RH) from a global model, several pre-existing diagnostic RH-to-cloud schemes were tested to forecast global fractional cloud cover in a postprocessor format. Since none of the schemes tested provided a superior cloud forecast when compared to Air Force Global Weather Central's (AFGWC) operational 5LAYER cloud forecasts, a new RH-to-cloud scheme was developed by relating cumulative frequencies of forecast RH to cumulative frequencies of analyzed cloud cover from the AFGWC RTNEPH cloud analysis. This scheme creates a series of forecast time-dependent RH-to-cloud curves that can be temporally updated to account for changes in season, cloud analysis, or forecast model, The global model used was a spectral-type developed by the Geophysics Laboratory (GL) using parameterized diabatic physics presently incorporated in the operational GSM (global spectral model) at AFGWC.

Book excerpt: This report describes the results of the first 15 months of a two- year effort aimed at evaluating the advanced physics global spectral model (APGSM) developed by the Phillips Laboratory, in comparison with the currently operational GSM at Global Weather Central (GWC). Preliminary results from the verification of forecasts from the GWC GSM and APGSM, using the GWC analyses as a reference, are presented. The compaction and analysis of RTNEPH cloud data in preparation for generating and verifying cloud forecasts from the APGSM are described. The development of a cloud forecast scheme based on an application of the cloud curve algorithm to synoptically defined weather regimes is described.

Available in PDF, EPUB and Kindle. Book excerpt: The completed research is in the area of cloud prediction with a high resolution global model. We have extended our studies on the handling of implicit clouds (i.e. clouds specified as a function of prevailing humidity). We have also examined this problem in the context of rainfall initialization (called physical initialization). We demonstrate a strong positive impact on cloud forecasts from such an initialization. We have also made a start on the problem of explicit cloud forecasts using cloud water mixing ratio and cloud fractions as basic forecast variables. Our preliminary results, described in the final report, are very encouraging. Mannoji (1994) has in fact noted a slight superiority of the explicit over the implicit scheme. That work was performed using a low resolution global model. Further work on the improvement of the explicit scheme at higher resolution is required. Cloud prediction, Global modelling of clouds.
