N 50 dBZ. This difference has to be connected together with the distinct atmospheric Tasisulam site systems operating inside the area, exactly where the SCM stands out. The behavior of vertical reflectivity profiles located in this study is also constant with findings for convective circumstances and/or lightning occurrence in other areas around the globe, such as inside the states of Oklahoma and Kansas, USA [86], in Henan province, China [114] and for various representative regions in tropical and subtropical locations [115]. five. Conclusions This study evaluated, in pioneering style, the behavior of microphysical properties as a function of occurrence and non-occurrence of lightning in the Northeast area of Brazil, also because the spatial distribution of those traits inside the region. The use of details in the TRMM satellite proved to be a fundamental option for regions for example NEB, exactly where there is a significant territorial extent and no efficient coverage by ground radar and lightning location systems. The evaluated cloud microphysical parameters showed that clouds with lightning have qualities really diverse from these without having electrical discharges. Electrified clouds are inclined to possess a higher quantity of ice (IWP), possess a slight rise in the height from the freezing level (FH), and have larger values of SP, CP and RWP. Large-scale atmospheric systems which include ITCZ and SACZ have a robust influence on the spatial distribution on the microphysical characteristics evaluated in this study. Smaller-scale systems which include UTCV and Upper Bolivia also influence these parameters by facilitating convection, specifically throughout the Southern Hemisphere summer time. The tertile strategy proved to become of terrific value for spatial division of NEB into lightning occurrence classes, because the application of ANOVA, followed by the Tukey test showed a significant distinction between most regions (remedies) for the respective variables measured.Remote Sens. 2021, 13,18 ofThe evaluation of clouds’ vertical structure by way of the vertical reflectivity profiles showed the existence of variations between coastal and ML-SA1 Purity & Documentation inland regions, furthermore to highlighting the partnership between higher reflectivity connected with larger lightning densities. New perspectives for use of lightning measured by the Geostationary Lightning Mapper-GLM sensor onboard the GOES satellite [116] were produced from these results, together with the possibility of employing information in the continuous monitoring with the region studied. Hence, future operates can observe a storm throughout its life cycle, with greater temporal resolution. Generally, the assessment of convective initiation and lightning initiation conditions will help to enhance the understanding of atmospheric patterns that precede lightning occurrence and to lessen its harmful effects.Author Contributions: All authors contributed to this paper: conceptualization, L.P.d.A., W.A.G., E.V.M. and D.T.R.; methodology, L.P.d.A., W.A.G., E.V.M. and D.T.R.; computer software, L.P.d.A., D.T.R., P.R.M. and M.P.A.d.S.; writing–original draft preparation, L.P.d.A.; writing–review and editing, W.A.G., E.V.M., D.T.R., P.R.M. and M.P.A.d.S.; visualization, L.P.d.A., W.A.G., E.V.M., D.T.R., P.R.M. and M.P.A.d.S.; supervision, W.A.G. and E.V.M.; funding acquisition, L.P.d.A., W.A.G., E.V.M., D.T.R., P.R.M. and M.P.A.d.S.
