On the dependence lifetime-diameter for Ball Lightnings

Methods for non-parametric regression have been applied for pair lifetime and diameter of Ball Lightnings (BLs) that disappear through explosion, extinction and decay. BLs lifetime increases in case of BL, that disappear through extinction and decay in range of diameters 0.5-100 cm Lifetime of BLs, that disappear through explosion, increases at diameters smaller than 60 cm and decreases for greater diameters. Comparison with data on experimentally obtained fire balls and with existing theories was conducted Polymer BL theory gives a possibility to explain obtained results.
