A Deterministic Rapid Intensification Aid

Rapid Intensification of a Sheared Tropical Storm

A weak tropical storm (Gabrielle in 2001) experienced a 22-hPa pressure fall in less than 3 h in the presence of 13 m s ambient vertical wind shear. A convective cell developed downshear left of the center and moved cyclonically and inward to the 17-km radius during the period of rapid intensification. This cell had one of the most intense 85-GHz scattering signatures ever observed by the Tropi...

Cheiloscopy: A Deterministic Aid for Forensic Sex Determination

Background: Cheiloscopy, the study of lip prints, is an upcoming tool for the identification of persons. The lip print of every person is unique and can be used to fix personal identity. Aim: The prime objective of the present study was to ascertain whether the lip prints behold the potential for determination of sex of the individual from the configuration. Methods: The lip prints were recorde...

The Energetics of the Rapid Intensification of Hurricane Earl ( 2010 )

Rapid intensification and the bimodal distribution of tropical cyclone intensity

The severity of a tropical cyclone (TC) is often summarized by its lifetime maximum intensity (LMI), and the climatological LMI distribution is a fundamental feature of the climate system. The distinctive bimodality of the LMI distribution means that major storms (LMI >96 kt) are not very rare compared with less intense storms. Rapid intensification (RI) is the dramatic strengthening of a TC in...

An analytical model for the rapid intensification of tropical cyclones

The nonlinearity and complexity of the primitive equations have been key obstacles to our understanding of tropical cyclones (TCs), particularly in relation to the dynamical processes leading to their rapid intensification. In this study, an axisymmetric model, in which all nonlinear terms in the horizontal momentum equations are retained, is used to examine analytically the effects of organize...
