This contribution summarizes key research advances on tropical cyclone(TC) intensity change from 2014-2018 from the Ninth International Workshop on Tropical Cyclones(IWTC-9). Research advances on intensity change have occurred on many fronts, including improved understanding of the role of vertical wind shear(VWS) and its impact on convection, surface fluxes, ocean eddies, dry/dusty air intrusions, eyewall replacement cycles(ERCs), spiral rainband dynamics, eyewall instability and inner-core mixing, and the mechanisms by which TCs intensify. This summary highlights a number of these important advances. Additionally, some new and emerging topics on TC intensity change have recently been elucidated: the important role of vortex structure on the subsequent intensification rate, the maximum potential intensification rate(MPIR), and the role of upper level outflow on TC intensity change.

The purpose of the research is to develop a dynamical theory of phase transitions in crystalline structures, when except for temperature, the pressure is acting. So, the phase diagram temperature-pressure (dimensions) must be constructed. In general case, it is a complicated question, which can be solved for simple models of crystal, as three atomic models, introduced in the work of Frenkel [1]. In this model, three identical atoms are placed on the straight line and interact with the forces, which can be described by the expression, given in the article of Lennard-Jones [2]. Such simple model may have success, when the crystalline structure is simple, which consists of one type of atoms, for example: carbon. The model was generalized to cubic cell model with a moving atom in the inner part of the cell. The rigorous calculation of phase diagram for transition graphite-diamond shows some similarity with results of numerous experimental investigations (which are not discussed here). So, the way of phase diagram calculation may attract attention.
