A STATISTICAL MODEL FOR THE MID LATITUDE TROPOPAUSE AND JET STREAM LAYER

A STATISTICAL MODEL FOR THE MID LATITUDE TROPOPAUSE AND JET STREAM LAYER

Tropopause and level of maximum wind charts are derived from objective analyses of the 500, 300, 150 and 100-mb height and wind fields. Regression equations, based on 24-hr changes, are developed to permit reconstruction of the layer given the history and current 500-mb data. This new derived layer...

Zusammenfassung:Tropopause and level of maximum wind charts are derived from objective analyses of the 500, 300, 150 and 100-mb height and wind fields. Regression equations, based on 24-hr changes, are developed to permit reconstruction of the layer given the history and current 500-mb data. This new derived layer is examined statistically with respect to its adequacy as a three-demensional first-guess field for the current objective analyses for this layer, and also as a method for forecasting the layer from a barotropic 500-mb prognostic chart.
