dos Sistemas Convectivos de Mesoescala que afetaram o Estado do
Rio Grande do Sul-RS (SCMRS) no ano de 2006, utilizando a
t{\'e}cnica ForTrACC (Forecasting and Tracking of Active Cloud
Clusters). Foram utilizadas imagens brutas do sat{\'e}lite
GOES-12 (Geostationary Operational Environmental Satellite) do
canal 4, com resolu{\c{c}}{\~a}o espacial no seu ponto
subsat{\'e}lite de 4 km x 4 km e resolu{\c{c}}{\~a}o temporal
de ½ hora, do per{\'{\i}}odo de 01/01/2006 a 31/12/2006. Essas
imagens foram fornecidas pela Divis{\~a}o de Sat{\'e}lites e
Sistemas Ambientais do Centro de Previs{\~a}o de Tempo e Estudos
Clim{\'a}ticos do Instituto Nacional de Pesquisas Espaciais
(DSA/CPTEC/INPE) e serviram como base de dados para a
utiliza{\c{c}}{\~a}o da t{\'e}cnica ForTrACC. Os resultados
mostraram que: i) a maioria dos SCMRS ocorreu nos trimestres mais
quentes do ano e apresentou tempo de vida entre 6 e 12h; ii) SCMRS
com maior tempo de vida cobriram {\'a}reas maiores; iii) SCMRS
maiores e mais longos foram observados em JAS (jul, ago, set); iv)
os SCMRS apresentaram as 3 fases do seu ciclo de vida
distribu{\'{\i}}da ao longo do dia; v) os SCMRS tiveram
inicia{\c{c}}{\~a}o preferencial sobre o continente e vi) os
SCMRS apresentaram trajet{\'o}ria m{\'e}dia preferencial de
oeste para leste. ABSTRACT: It was studied the seasonal physics
features of the Mesoscale Convective Systems that reached Rio
Grande do Sul (RS) State (MCSRS) in 2006, using ForTrACC tool
(Forecasting and Tracking of Active Cloud Clusters). Channel 4
GOES-12 (Geostationary Operational Environmental Satellite) images
from 2006 year, with 4 km × 4 km spatial resolution in the
subsatellite point and 1/2 hour temporal resolution were used.
These images were provided by DSA/CPTEC/INPE (Divis{\~a}o de
Sat{\'e}lites e Sistemas Ambientais do Centro de Previs{\~a}o de
Tempo e Estudos Clim{\'a}ticos do Instituto Nacional de Pesquisas
Espaciais) and were the data basis to the ForTrACC tool. The
results showed that: i) most MCSRS occurred in the warmest
quarters and showed lifetime between 6 and 12h, ii) MCSRS with
higher lifetime covered larger areas, iii) the largest and most
long MCSRS were observed in JAS (Jul, Aug, Sep); iv) MCSRS
presented the three phases of their life cycle distributed
throughout the day; v) MCSRS had preferential initiation over the
continent, and vi) MCSRS presented mean preferential trajectory
from west to east.",
