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.
Mid-latitude cyclones form just as other low pressure systems do with the divergence of air high in the atmosphere. The jet stream plays a major role in the location of mid-latitude cyclones. The jet stream brings down colder air from the north into the southern regions of the United States.
