In the present work, is analyzed the images sequence of the weather radar and the synoptic information and of mesoescale, that characterized a hailstone occurred in the province of The Tunas, Cuba, 10 of May of 1999, that only it is comparable, in this territory, with a similar event that occurred in the month of March of 1963. This phenomenon, lasted approximately a hour, that, united to the diameter more common, of its hail (3 cm), we could relate it to the fact of the fact that 72 hours after occurred the event, are seen such precipitation residues.
The day was characterized by a strong vertical temperature gradient, convergence of the wind in surface and a divergence area in the high levels of the troposphere. The echoes that produced the hailstone, were moved to the right of the address of the wind in the levels of 700 and 500 hPA and had half hour before be begun the event, an arched configuration, being converted later in a multicell, with maximum reflectivity(Zmáx) of dBZ, 20.5 km of top, vertically integrated water (VIL) maximum of 101.0 Kg/m2, height of Zmáx of the column (HZ) 12.3 Km and intensity of the rainfall of 221 mm/h. This multicell registered the highest values of Zmáx and VIL documented in Cuba and the echo that produced the solid rainfall as well as the multicell in itself, they maintained more than 1˝ hour the HZ, by above of the level of the isothermal of zero degree centigrade, and were observed the highest gradients of VIL measured until the moment in Cuba. Such characteristic is consideration reasons that are exposed in this work.
