The impacts of the Madden-Julian Oscillation (MJO) on polar low (PL) activity are examined. We found that PL frequency increases over Irminger Sea and decreases Norwegian-Barents Seas following MJO Phases 2–4, nearly opposite changes for 6–8. Further analysis reveals significant anomalies static stability low-level baroclinicity different phases, which have opposing effects in many regions. dia...

Abstract Recent studies have examined moist entropy (ME) as a proxy for static energy (MSE) and the relative role of underlying processes responsible changes in ME that potentially affect MJO propagation. This study presents an analysis intraseasonally varying (ISV) anomalies throughout lifetime observed events. A climatology continuing terminating events is created from event identification al...

MR SUGARMAN, A 64-YEARold patient with diabetes, comes for his 15-minute visit with Dr Madden. After evaluating Mr Sugarman’s acutely painful knee and treating his gastroesophageal reflux disease, Dr Madden has 3 minutes left to assess diabetic control.
