CACERES DIAZ, Luis Enrique  y  GONZALEZ RAMIREZ, Carlos Manuel. Behavior of lightnings in storms that produce hail fall. Rev. Cubana Met. [online]. 2023, vol.29, n.1  Epub 01-Mar-2023. ISSN 2664-0880.

In this work, a total of 11 storms in which hail fall was reported and 8 storms in which it was not reported, which occurred in the region of Artemisa, Havana and Mayabeque, during the year 2020, were analyzed. the relationship between lightnings and the fall of hail in storms that produces it. For its development, the hail reports extracted from the monthly summaries prepared by the Forecast Center of the Cuban Institute of Meteorology were used, in addition to the data of lightnings measured by the Earth Networks receiving station located in Casablanca, as well as the observations of the Key West weather radar. The Pearson linear consequence was obtained for the analyzed cases. As a result, it was obtained that, in the hail-producing storms, the lightnings and reflectivity showed a linear impact of 0.86, a value very similar to that of the storms that did not produce hail, which was 0.85. However, the greatest difference was observed in the number of discharges per observed reflectivity, which in the case of hail-producing storms, the reflectivity values between 60 and 69 dBZ were the ones with the highest average discharges per minute, with a value of 10, while in those where hail did not fall, the interval between 50 and 59 dBZ presented a value of 8 average discharges per minute.
