Satellite Radiothermovision Analysis of the Evolution of a System of Interacting Typhoons

In this paper we develop further the satellite radiothermovision methods for analyzing the evolution of tropical cyclones. The complicated case of Goni and Atsani interacting typhoons is considered. It has been shown that, although their interaction does not explicitly influence the features of the typhoon trajectories, indications of the formation of complex advective fluxes in the lower troposphere can be revealed from both a qualitative analysis of miscellaneous satellite data and a quantitative estimation of latent heat advection. At the same time, in contrast to the previous works, we had to introduce the integration contours of a complex form (differing from a circular one) into the analysis, so that the energy balance of the typhoon system is correctly described. In a general way, defining such contours is a separate problem whose solution is probably related to the invocation of a large volume of additional satellite information. Due to the peculiarity of the considered case of Goni and Atsani twin typhoons, we demonstrated the effectiveness of a simplified approach that uses a composite contour formed by overlapping two circular ones. Generally, as in the cases previously considered, we found the interrelation between the intensification and dissipation of typhoons (tropical cyclones) and the modes of convergent and divergent advection of latent heat with amplitudes sufficient to support the total power of the system.
