10 0 obj endobj endstream Frontogenesis • Terminology: frontogenesis – creation or intensification of a front (front + genesis, birth, creation, formation, Genesis, gene, generate….) A warm front is a narrow line of warmer temperatures and essentially where much of the precipitation occurs. 6 0 obj The process associated with the creation of new fronts or the regeneration of decaying fronts already in existence is called frontogenesis. (noun) “Frontogenetical Circulations and Stability” is a Webcast by Dr. James T. Moore that focuses on an overview of different stability types, including convective, potential, inertial, conditional and symmetric, the concept of frontogenesis and associated circulations. Explain the characteristic fcatures of Frontogenesis and Frontolysis . Table 4-2 shows the numerical average life cycle of a, typical unstable wave cyclone from initial development, to cyclolysis.

A temperature difference is essential in the definition of a front because it implies a density difference. /TT1.0 9 0 R >> >> x��wTS��Ͻ7��" %�z �;HQ�I�P��&vDF)VdT�G�"cE��b� �P��QDE�k �5�ޚ��Y�����g�} P���tX�4�X���\���X��ffG�D���=���HƳ��.�d��,�P&s���"7C$ 1. As the occlusion continues to extend outward, the, cyclonic circulation diminishes in intensity (the, low-pressure area weakens), and the frontal movement, slows down (view F).
