| Resumo | In recent years the research about Mesoscale Convective Systems (MCS) electrical activity has been increased, probably due to the raise of severe weather conditions. The knowledge of the clouds processes associated to the occurrence of cloud to ground lighting in MCS can be used as a nowcasting tool to support the extreme events mitigation decision. The join use of cloud to ground lightning data ground sensors and MCS physical properties data obtained from the geostationary satellite infrared channel has become essential information to help convective and electric activity nowcasting over regions with intense occurrence of lightning. In particular, Brazil has an extensive land area and is near to the equator, it is intensely affected by this phenomenon, being hit by around 50 million of the cloud to ground lightning annually, causing major damage to the sectors of electricity energy, telephone and telecommunications. This work presents the relationship between cloud to ground lightning occurrence with some MCS physical proprieties and characterize the lifecycle evolution differences between MCS with (thunderstorm) and without lightning (storm). The basic information were obtained from the GOES-10 satellite infrared images, a MCS tracking algorithm called Forecast and Tracking the Evolution of Cloud Clusters (FORTRACC) and cloud to ground lighting data from the Brazilian Atmospheric Discharge Detection Network (BRASILDAT) for the São Paulo state region in the period from 2007 to 2009. The combined information from infrared channels with cloud-ground lightning enabled characterizes about MCS seven hundred, between fourth hundred thunderstorms and three hundred storms. The diurnal cycle showed the maximum normalized area expansion happened tree hours (15 hours GMT) before the maximum lightning occurrence (18 hours GMT). The study of the physical proprieties had evidenced that MCS size and temperature had strong influence on lightning occurrence, a linear dependence and exponential relationship was characterized, where the most intense lightning occurrence lower 210 K was found. Thunderstorm life cycle duration is about 2.5 hours longer than storms life cycle duration, also thunderstorm presents larger size and initial area expansion. Therefore, initial area expansion, life cycle duration and size can be used as a proxy of the cloud to ground lightning. Moreover the most MCS electrical activity was characterized between initiation stage and maturation, and the same happened to lightning average density (cloud-ground lightning.km-2). This newest principal results found in South America showed considerable potential to be used in near futures for severity diagnostic and cloud-ground lightning nowcasting. |
