20 maiores acumulados di{\'a}rios de cada regi{\~a}o. Para a
escolha desses dias foi utilizado os dados de descargas
atmosf{\'e}ricas nuvem-solo da rede BrasilDat. A an{\'a}lise
meteorol{\'o}gica utilizou dados de rean{\'a}lise do NCEP/NCAR
(para plotar as vari{\'a}veis meteorol{\'o}gicas), imagens de
sat{\'e}lite georrefrenciadas e imagens de radar. Dos resultados
pode-se observar que, dentre os 40 casos selecionados, as
tempestades que geraram esses acumulados di{\'a}rios tiveram como
causa principal a termodin{\^a}mica (60\% dos casos); os demais
dias foram influenciados por sistemas de escala sin{\'o}tica
(40\% dos casos). Esses sistemas de escala sin{\'o}tica s{\~a}o
os cavados, ZCAS e sistemas frontais Por meio da an{\'a}lise das
imagens de sat{\'e}lite e de radar, no hor{\'a}rio de pico das
descargas, pode-se dizer que o comportamento da temperatura de
topo da nuvem de tempestade e os valores de refletividade do radar
n{\~a}o apresentaram rela{\c{c}}{\~a}o direta com o pico de
descargas. As c{\'e}lulas convectivas com a menor temperatura de
topo nem sempre estavam relacionados com os maiores picos de
descargas. O mesmo ocorre com a refletividade do radar. ABSTRACT:
The southeastern region of Brazil is subject to the occurrence of
several meteorological phenomena during the summer months of the
year. Thunderstorms with lightning occur due to thermodynamic
conditions and systems of synoptic scale. This study aims to
examine the meteorological conditions, on a scale synoptic, which
generated the highest number of lightning in the metropolitan
regions of S{\~a}o Paulo and Campinas, in the summer months,
during the period from January 2012 to March 2015. In each region
the 20 largest daily accumulated were considered. To choose these
days we used the data of cloud-to-ground lightning, of BrasilDat.
For the weather analysis, we used data from review of the
NCEP/NCAR (for plotting the meteorological variables),
georeferenced satellite imagery and radar images. From the results
it can be observed that among the 40 selected cases, the storms
that cause those daily accumulated had as the main cause the
thermodynamics (60\% of cases); the remaining days were
influenced by systems of synoptic scale (40\% of cases). These
systems of synoptic scale are dug, ZCAS and front systems. Through
the analysis of satellite images and radar, at peak times of
cloud-to-ground lightning, it can be said that the behavior of the
temperature of top of the storm cloud and the values of
reflectivity of the radar showed no direct relationship with the
cloud-to-ground lightning peak. The convective cells with the
lowest temperature of top were not always related to the greatest
cloud-to-ground lightning peak, the same occurs with the
reflectivity of the radar.",
