Abstract
:
Analysis of the kinetic energy budget for a developing winter-type cyclone is presented. This case represents a middle latitude cyclone that is developed significantly north of the Mediterranean Sea. The development occurred as cold fresh air is advected to the rear of the system. The role of the polar and subtropical jets is discussed. It found that horizontal flux convergence constitutes the major energy source and is the main cause for maintaining the strength of the upper tropospheric jet maxima. Generation of kinetic energy via cross-counter flow is a persistent sink at the most days. Dissipation of kinetic energy, computed as a residual, has local maxima both in the lower troposphere and near the jet stream level. Spatial fields of the energy terms show that the most intense energy processes occur associated with deep cyclogenesis. The vertical transfer of kinetic energy acts as s source of kinetic energy to middle troposphere and lower stratosphere.
