utilizou como {\'a}rea de estudo a Regi{\~a}o Metropolitana de

CCATT-BRAMS-JULES ( Coupled Chemistry Aerosol and Tracer Transport
model to the Brazilian Developments on the Regional Atmospheric

modelo, al{\'e}m de ser n{\~a}o hidrost{\'a}tico como as

computacional e na representa{\c{c}}{\~a}o dos sistemas

espec{\'{\i}}ficas para estudar os processos de
intera{\c{c}}{\~a}o entre os sistemas de tempo severo, a ilha de
calor urbana e os aeross{\'o}is. Os resultados mostraram que o
produto de precipita{\c{c}}{\~a}o derivado de sat{\'e}lite
MERGE estimou melhor a precipita{\c{c}}{\~a}o ao ser comparado
com outros produtos e com os resultados das simula{\c{c}}{\~o}es
feitas com o modelo. Os produtos GSMaP calibrado e GPM_3IMERGHH
apresentaram desempenhos semelhantes ao CCATT-BRAMS-JULES. Em
rela{\c{c}}{\~a}o ao objetivo principal do trabalho, quando
foram modificadas exclusivamente as concentra{\c{c}}{\~o}es dos
aeross{\'o}is na atmosfera, n{\~a}o se observou mudan{\c{c}}as

nas {\'a}reas de m{\'a}ximos e m{\'{\i}}nimos acumulados de
precipita{\c{c}}{\~a}o. As diferen{\c{c}}as observadas foram
principalmente no tamanho e intensidade dos sistemas de nuvens. As
mudan{\c{c}}as nas caracter{\'{\i}}sticas da
superf{\'{\i}}cie, com a substitui{\c{c}}{\~a}o da mancha

consequ{\^e}ncia varia{\c{c}}{\~o}es nas
localiza{\c{c}}{\~o}es das c{\'e}lulas que formam as
tempestades, variando a forma e momentos em que elas passam pelos
seus est{\'a}gios de desenvolvimento. Em rela{\c{c}}{\~a}o
{\`a} intensidade da precipita{\c{c}}{\~a}o, esta sempre foi
maior nos testes de sensibilidade em que se realizou a
substitui{\c{c}}{\~a}o da mancha urbana pela

The Numerical weather prediction models usage is essential to be
able predict the atmosphere conditions with accurate detail and
best estimates. In this case, models with efficient dynamic cores
and advanced physical parameterizations adapted to the study
regions it is of essential use. These characteristics, jointly
with high spatial resolution, allow to represent the impact of
morphological differences and urban spatial structure on
meteorological phenomena successfully, mainly those related with
severe weather. In this research, Metropolitan Region of S{\~a}o
Paulo was used as a study area to analyse the particulate material
impacts and surface processes in the developing stage of a
thunderstorm. CCATT-BRAMS-JULES (Coupled Chemistry Aerosol and
Tracer Transport model to the Brazilian Developments on the
Regional Atmospheric Modeling System and Joint UK Land Environment
Simulator) systems were used in this research. The new model
version, besides to being non-hydrostatic as the previous
versions, include new features and functionalities which turned
out to be more efficient from a computational perspective and in
the meteorological systems representation. With the objective of
diagnosis, validation and calibration of the modeling system,
several sets of simulations were performed, besides a comparison
in the precipitation representation performance between the model
and the derived products from meteorological satellites
measurements. Afterwards, with CCATT-BRAMS-JULES system
calibrated, other sets of simulations with specific
characteristics were performed and analyzed with the aims to study
the interaction processes between severe weather systems, the
urban island heat effect, and aerosols. The results showed that
the precipitation product derived from satellite better estimates
precipitation is the MERGE, in comparison with other products and
with the simulations results made with the model. The GSMaP
products calibrated and GPM_3IMERGHH shows similar performances to
the CCATT-BRAMSJULES. In the main aim of the research, observed
that modifying exclusively the concentrations of the aerosols in
the atmosphere, do not produce any change in the location of
convective core nor in the areas of accumulated maximum and
minimum precipitation. The observed differences were mainly in the
size and intensity of these cloud systems. Changes in the surface
characteristics, as a substitution of the urban region by
vegetation, did bring as a consequence variation in the cells
location that form the storms, varying the form and the moment in
which they pass through their growth stages. In relation to the
precipitation intensity, was always higher in the sensitivity
tests that vegetation was placed instead of the urban region. This
study will contribute to the implementation of an integrated
system of numerical weather and chemistry of the atmosphere
forecast in high spatial resolution with the CCATT-BRAMS-JULES.",
