    "abstract": "The results are presented of an analysis, with the help of the method of\nmultilevel dynamical contrasting of the images, of available databases of the\nimages of tornado. This analysis extends some preliminary results on\nidentification of skeletal structures in tornadoes (Phys. Lett. A 306 (2002)\n175) and enables us to apply to the case of tornado our former hypothesis for\nthe probable role of nanotubular dust in the origin and stability/longevity of\nfilamentary structures of a skeletal form in electric discharges. A hypothesis\nfor the contribution of nanotubular dust to initiation of tornadoes is\nsuggested, in which a key role is delivered to ability of the hypothetical\nskeleton inside the thundercloud to provide fast long-range transport of\nelectricity. Thus, initiation of tornado is suggested to be an electrostatic\ninstability caused exclusively by the presence and special structuring of a\nnanodust.",
