Development of a Technique for Short-Term Prediction of Hydrometeors Using Advection and Physical Forcing.
Abstract
This interim scientific report describes initial stages of a project to enable prediction of humidity and cloudiness in mesoscale areas and their short-term changes. The performance of the LFM-II humidity forecasts is evaluated as an indicator of large-scale humidity patterns and their changes. The usefulness of various meteorological parameters as potential predictors of cloudiness and cloudiness change is assessed through correlation studies. The predictor fields are compared to brightness and brightness change fields derived from satellite imagery. Interactive computer programs to obtain quantitative data from satellite imagery are described. (Author) The ability of a humidity estimation technique, using hourly surface weather observations, to diagnose radiosonde-derived humidity observations is evaluated. Experiments in forecasting nighttime convection are described.
