Increased water-vapor content in the atmosphere of tropical latitudes as a necessary condition for the genesis of tropical cyclones

Description
Summary:The hypothesis about the interrelation of the integral water-vapor concentration (from data of microwave satellite systems) and plural tropical cyclogenesis in cyclonogenerating water areas of the World Ocean in 2001 is verified with the aid of the EVA-01 (IKI RAN) database (DB) with elements of the objectrelation type formed by the authors. It is experimentally proved in the work that there is a critical value of the integral water-vapor concentration (a peculiar necessary condition) at which the mature form of a tropical cyclone (TC) is formed with a lifetime exceeding 24 h. It is also experimentally proved that, in the same time interval, there is another group of TCs with a short lifetime (less than than 24 h) which do not possess a clearly pronounced boundary value of the water-vapor intensity and can be formed in a wide range of its values. The relations between the regions with an increased concentration of water vapor and genesis of TCs have become obvious only with the use of object-relation computer technologies.
