Analysis of the severe local storm that occurred on May 5, 2018 in the province of Camagüey
Main Article Content
Abstract
The present investigation is based on the study of a Severe Local Storm, which occurred in the city of Camagüey on May 5, 2018, which was related to the presence of a surface trough, reflecting a higher cold fall in average levels of the troposphere with the presence of currents from the northeast and east, being the second most influential condition in our province, which together with strong warming and increased energy make the necessary combination of convective activity and especially the fall of hail and linearly strong winds which can cause damage to the economy, the population, and even the loss of human lives. The investigation presents an analysis based on the survey of the 1800 UTC schedule where the values obtained from the main thermodynamic indices were analyzed, such as the potential convective energy available (CAPE), the survey index (LI), total total index (TT), crossed total (TC), Kaidach index (KI) and the severe weather threat index (SWEAT). The average behavior of the humidity in the surface layer at 3 and 6 km respectively is analyzed, as well as the vertical structure of the wind, characterized by the levels of 850, 700, 600 and 500 hPa. The result that is exposed can serve as a guide during the development of meteorologists' operational work in meteorological surveillance.
