Abstract
Energy features of the succession of interrelated tropical cyclones (plural cyclogenesis) in the oceans of the Southern Hemisphere (the southern part of the Indian Ocean and the southwestern part of the Pacific Ocean) over February 2008 are comprehensively analyzed on the basis of the method of combining different-scale data of the infrared and radio thermal satellite sounding. The data of infrared thermal channels of the geostationary Meteosat-7 satellite and the results of reconstruction of integral water vapor from data of the AMSR-E microwave complex of the Aqua satellite were used. The analysis showed that the region where water vapor has an increased integral concentration is the most effective channel for pumping the latent heat energy from the tropics into midlatitudes. Each cyclone captures this region from the tropical zone and retains it throughout the entire stage of its own evolution with the aid of the jet spiral bridge. The quantitative estimates of the latent energy of the central equatorial region of water vapor in the intratropical convergence zone (ITCZ) of the Indian and Pacific oceans were a basically new result, as well as the detection of considerable time variations in the latent heat associated with the ejection of coherent water-vapor regions into high latitudes by plural cyclogenesis.
