Tropical cyclones (TC) are the most powerful sources of thunderstorm activity<br />
(and, correspondingly, of the electromagnetic activity within the wide frequency<br />
range) in the terrestrial atmosphere with spatial sizes of a perturbed area up to<br />
1000 km and vertical development up to 16…20 km with charged water drops movement<br />
speeds up to 30 m/s. The study assesses physical potentialities of the generation<br />
by the systems of gamma-ray emission that can be monitored by low-orbiting<br />
spacecraft like “Chibis-M”. In view of quasichaotic nature of trajectory characteristics<br />
of tropical cyclogenesis we examine the navigation problem of “meetings<br />
frequency” of the surface projection of the microsatellite orbit and the trajectory<br />
of tropical cyclones in the active cyclogenerative water areas of the World Ocean.<br />
The navigation problem should be dealt with in two aspects: statistical and deterministic.<br />
In the first case the averaged field of trajectories in each of cyclogenerative<br />
water areas is taken into consideration; in the second one detailed fixing of the active<br />
tropical cyclone is carried out and prognostic suppositions concerning the potential<br />
motion trajectory in accordance with the optic and microwave satellite data<br />
are made.<br />
Owing to the intense work done by the Operative group controlling the complex<br />
of scientific equipment (CSE) “Groza” of microsatellite “Chibis-M”, it became<br />
possible to make periodic observations on TC 27W Wukong, evolving from<br />
25.12.2012 to 30.12.2012, and on TC 08S Narelle, developing from 10.01.2013 to<br />
15.01.2013 by the northern coast of Australia, with the use of RFA (26) and MCC<br />
(multifunctional computational complex) (0.1…40 kHz).<br />

Advanced international investigations of the correlation between tropical cyclones<br />
(TCs) and the ionosphere are connected with extreme difficulties of proving<br />
the action of possible mechanisms of TC effect on the ionosphere. TCs are the<br />
greatest troposphere disasters. Powerful surges of charged particles and neutrals,<br />
internal gravity wave radiation and low-frequency electromagnetic wave radiation<br />
from central points of TCs to considerable altitudes and distances are a manifestation<br />
of TC action mechanisms. The authors of this presentation analyze the ionosphere<br />
parameters, received in the process of both ground and satellite probing<br />
above TC and at a certain distance from it. Cyclones, being examined in the paper,<br />
functioned in waters of the Indian Ocean and the Pacific Ocean in different years.<br />
