Abstract
An empirical study is made of the relationship of precipitation occurrence to vertical velocity and dewpoint depression. Based on this work, a method of forecasting precipitation occurrence is developed. The method uses two predictors, the prognostic charts of 500-mb. vertical velocity made by the JNWP Unit with a thermotropic model, and the dewpoint depression. Tests of the method suggest it is widely applicable in the eastern United States.Keywords
