"The varied terrain of southern California and its proximity to the Pacific Ocean results in many unique forecast challenges. Therefore unique approaches to diagnosing and forecasting weather conditions in this area are necessary. The purpose of this Forecaster's Handbook is to present a variety of approaches to not only better understand the meteorological processes involved in the area, but to somehow connect them to methods of forecasting for the area. A key component of this study is to employ short term climatological approximations (STCA). Data sets of generally less than 10 years are found to at least give a reasonable approximation of conditions expected with certain meteorological parameters. Forecaster hints are 'quick and dirty' guidance for the forecaster to get an initial idea of the types of weather occurrences that are possible for certain parameters, and more information is embedded in the discussions. Also for more detailed information the references can be consulted. Examples of the different types of events are included. (Of course, this information is to be supplemented with computer model guidance). Although not totally comprehensive, it is hoped that this information helps to increase understanding of the phenomena that occurs in the extreme southwestern corner of our nation and helps to improve the ability to forecast them"--Abstract.
