Objective specification of monthly mean surface temperatures in the United States during the winter season

Conference ·
OSTI ID:5414190
In preparing its 30-day outlooks, the National Weather Service (NWS) first forecasts the mean 700 mb circulation pattern for the coming month and then interprets this pattern in terms of weather. Guidance for the second step is obtained by applying multiple regression equations that specify surface temperature anomalies from concurrent 700 mb height anomalies at a few grid points selected by screening. Until six months ago, these equations were based on 5-day mean data that was over 20 years old. The object of the present paper is to update and improve the old equations by rederiving from monthly mean data for a longer time period, larger number of cities, finer grid of heights, and larger area. In addition, regional differences in the relations between temperature and circulation will be highlighted. 12 refs., 15 figs., 5 tabs.
