Summary
Available potential energy (APE) and kinetic energy (KE) processes for a limited region, containing and moving with an extratropical cyclone system, are discussed. The available potential energy and kinetic energy budgets for an extratropical cyclone over the continental United States during various stages of its life cycle are computed for the period 20–21 March 1962. Baroclinic component of APE based on the specification of a reference state for the limited moving volume is considered. The APE generation values for the case study reported by Vincent, Pant et al. [18] are used in the generation part of the budget. Energy exchange processes including a large amount of probable subgrid to grid-scale interaction are discussed in relation to the behaviour of the cyclone.
Zusammenfassung
Es werden die in einem außertropischen Zyklonensystem in einem begrenzten Gebiet sich vollziehenden Umsetzungen von verfügbarer Energie (APE) und kinetischer Energie (KE) besprochen. Die Budgets der verfügbaren Energie und der kinetischen Energie werden für eine außertropische Zyklone über dem kontinentalen Bereich der Vereinigten Staaten für die verschiedenen Entwicklungsstadien in der Zeit vom 20.–21. März 1962 berechnet. Die barokline Komponente der APE wird basierend auf eine Spezifikation eines Referenzzustandes für ein begrenztes Luftvolumen in Bewegung betrachtet. Die Werte der APE Produktion, die in einer Untersuchung von Vincent et al. [18] veröffentlicht sind, werden für den Produktionskern der Bilanz verwendet. Energieaustauschprozesse werden mit Berücksichtigung bedeutender Wechselwirkungen von geringen Distanzen auf Gitterdistanzgröße in ihrer Beziehung zum Verhalten der Zyklone besprochen.
