| Summary: | adiabatic forcing for cyclogenesis, particularly during the amplification of the low-level cyclone-scale thermal wave by between the basic-state flow and perturbation PV field, complete quantitative estimation of the contribution made by cyclogenetic mechanisms such as Bi to cyclone growth. In all cyclone development. We introduce a method for partitioning diagnosed. Downstream translation of the upper wave is found directly to cyclone growth. eastern coast. The PTD developed by Nielsen-Gammon and evolution is dominated by processes involving interactions extratropical cyclogenesis occuring near the United States' is argued that this process is not one which contributes latter stages of cyclone growth, resulting in observed growth Lefevre (1996) is extended to enable diagnosis of low-level mechanism, as described by Hoskins et al. (1985), to Piecewise tendency diagnosis (PTD) is employed to quantify potential vorticity (PV) anomalies, thereby allowing a process most contributory to cyclogenesis. Upper-level wave processes associated with non-conservation of PV modulate the rates which differ significantly from those which are rather than by baroclinic amplification. We infer that superposition and amplification of the participating the contribution made by the baroclinic instability (BI) the cyclone growth into parts attributable to vertical three episodes examined, it is found that baroclinic to contribute significantly to low-level height falls but it winds associated with the upper perturbation PV field is the |
