Dissipative vortical solitons and tropical cyclones are the circular structures of fields keeping localisation at the distribution and depending in the movement from heterogeneity of system, for example, heterogeneities of fields of pressure, temperatures, humidity and other characteristics of atmosphere for cyclones. The analogy between intensive atmospheric vortices (tropical cyclones, TC) and dissipative vortical laser solitons is spent at their interaction with heterogeneity of fields or with other vortices. Results of numerical modelling of interaction vortical laser soliton with various heterogeneities of field and another soliton and comparison with movement of some TC according to microwave satellite monitoring (daily global radio thermal fields of the Earth from electronic collection GLOBAL-Field, ) are presented. The analysis of series of global radio thermal fields and results of numerical modelling have shown, that the heterogeneity of a field on which the vortices moves, even not so power, can change considerably a trajectory of vortices - and vortical laser soliton, and TC. Interaction with other whirlwind can lead to pushing away and even change of structure of whirlwinds. It is known, how the forecast of movement powerful TC, leading to huge destructions and human victims, is important, and, at the same time, it is known, how often official forecast does not correspond the problems because of TC can sharply change a direction of the movement during short time. The presented analogy has qualitative character, however can be involved for an explanation of some properties TC - for example, often observed and unpredictable at first sight sharp changes of trajectories of cyclones or occurrence of cyclones with "non-standard" trajectories. Our research shows necessity of tracking for heterogeneities of field on which TC moves ahead and in which evolves, i.e. necessity of satellite monitoring of changes enough remote atmospheric environment TC and the account of these data in theoretical models for the adequate forecast of TC trajectories.
