Conditions for the Full Realization of the Reserve of the Airmass Pressure Drop Determining the Possible Maximum Intensity of a Tropical Cyclone

L. I. Petrova

The maximum intensity of a tropical cyclone (TC) is determined by the reserve of the airmass pressure drop (RPD), tightly associated with instability energy. In addition to the rarely observed (close to dry adiabatic) temperature lapse rate in the lower troposphere, the conditions that ensure breaking of stable layers near the condensation level, both generated by convection and existing before its beginning, are necessary for the full RPD realization. Three typical stages were identified in the process of atmospheric convection, which leads to the full RPD realization in a given airmass. This allowed us to explain some peculiarities in the TC development.
