Planet{\'a}ria (CLP), ao se realizar simula{\c{c}}{\~o}es em
alta resolu{\c{c}}{\~a}o em um ambiente de floresta tropical
{\'u}mida na Amaz{\^o}nia. Neste ambiente, altamente convectivo
e com terreno extremamente complexo, o processo de modelagem da
CLP tropical ainda {\'e} um desafio. Uma descri{\c{c}}{\~a}o
incorreta ou insuficiente da superf{\'{\i}}cie pode conduzir a
uma defici{\^e}ncia na representa{\c{c}}{\~a}o dos processos de
transfer{\^e}ncia turbulenta entre a superf{\'{\i}}cie e a
atmosfera, gerando impactos diretos nas simula{\c{c}}{\~o}es
num{\'e}ricas de tempo. Diante disso, foram realizadas
simula{\c{c}}{\~o}es utilizando o modelo de superf{\'{\i}}cie
JULES acoplado ao modelo atmosf{\'e}rico BRAMS em alta
resolu{\c{c}}{\~a}o. Foram realizadas integra{\c{c}}{\~o}es a
partir do modelo com dois dom{\'{\i}}nios aninhados, com
espa{\c{c}}amento horizontal de grade de 5 km e 1 km, centrados
no s{\'{\i}}tio experimental da torre ATTO (Amazon Tall Tower
Observatory). Foi elaborado um mapa de uso do solo com
resolu{\c{c}}{\~a}o espacial de 30 metros e um mapa
topogr{\'a}fico a partir de imagens SRTM com
resolu{\c{c}}{\~a}o de 90 metros para implementa{\c{c}}{\~a}o
nas simula{\c{c}}{\~o}es de alta resolu{\c{c}}{\~a}o. O estudo
foi realizado em tr{\^e}s etapas: Realiza{\c{c}}{\~a}o de
testes de sensibilidade para se avaliar a influ{\^e}ncia do
refinamento do mapa de vegeta{\c{c}}{\~a}o das
simula{\c{c}}{\~o}es dos dom{\'{\i}}nios com
resolu{\c{c}}{\~a}o espacial de 5x5 km e 1x1 km,
verifica{\c{c}}{\~a}o do desempenho das
parametriza{\c{c}}{\~o}es de CLP com aninhamento de grade para
d02 e avalia{\c{c}}{\~a}o dos efeitos de altera{\c{c}}{\~o}es
das caracter{\'{\i}}sticas superficiais. A
implementa{\c{c}}{\~a}o de mapas de uso do solo em alta
resolu{\c{c}}{\~a}o resultou em uma melhor correspond{\^e}ncia
entre as previs{\~o}es e os dados observados, principalmente na
grade com resolu{\c{c}}{\~a}o espacial de 1 km. O modelo
apresentou bons resultados na estimativa de grande parte das
vari{\'a}veis analisadas, com exce{\c{c}}{\~a}o da intensidade
do vento (todos os n{\'{\i}}veis) e a radia{\c{c}}{\~a}o de
onda longa incidente. ABSTRACT: This study aimed to assess the
impact of surface model parameter adjustments on the Planetary
Boundary Layer (PBL) when conducting high-resolution simulations
in a humid tropical forest environment in the Amazon. In this
highly convective and extremely complex terrain, modeling the
tropical PBL remains a challenge. Incorrect or insufficient
surface descriptions can lead to deficiencies in representing
turbulent transfer processes between the surface and the
atmosphere, directly affecting numerical weather simulations. To
address this, simulations were conducted using the JULES surface
model coupled with the high-resolution BRAMS atmospheric model.
Integrations were carried out from the model with two nested
domains, with horizontal grid spacings of 5 km and 1 km, centered
on the Amazon Tall Tower Observatory (ATTO) experimental site. A
land-use map with a spatial resolution of 30 meters and a
topographic map derived from SRTM images with a 90-meter
resolution were developed for implementation in high-resolution
simulations. The study was conducted in three stages: Sensitivity
tests were performed to assess the influence of refining the
vegetation map for domains with spatial resolutions of 5x5 km and
1x1 km, verification of the PBL parameterizations performance with
grid nesting for d02, and evaluation of the effects of changes in
surface characteristics. Implementing high-resolution land-use
maps resulted in better correspondence between predictions and
observed data, especially at the 1 km spatial resolution grid. The
model yielded good results in estimating most of the analyzed
variables, except for wind intensity (all levels) and incident
long-wave radiation.",
