The lack of significant change on measures of comorbidity (BDI, HAM-A, and Rosenberg Self-Esteem Inventory) in meta-cognitive therapy may have been due to floor effects on these measures, as scores at baseline were, on average, not in the clinically significant range.
The life-cycle of a mid-latitude cyclone can be divided into 6 stages: Ã° stationary front, with opposing shear across the front. Ã° cyclone formation (cyclogenesis) begins as a cyclonic wave develops and amplifies. Ã° distinct poleward moving warm and equatorward moving cold fronts develop forming low pressure at apex.
Extratropical cyclones are classified mainly as baroclinic, because they form along zones of temperature and dewpoint gradient known as frontal zones. They can become barotropic late in their life cycle, when the distribution of heat around the cyclone becomes fairly uniform with its radius.
