a poeira retoma para a superf{\'{\i}}cie devido as

residual da poeira transportada na atmosfera inter age com a
radia{\c{c}}{\~a}o solar e terrestre, e altera os perfis de
aquecimento tanto da atmosfera quanto da superf{\'{\i}}cie.
Estas intera{\c{c}}{\~o}es modificam os balan{\c{c}}os de

convec{\c{c}}{\~o}es e precipita{\c{c}}{\~o}es. O ciclo da
poeira {\'e} modelada no \emph{CCATT}, o transporte da poeira
ocorre no \emph{MCGA-CPTEC}, e as intera{\c{c}}{\~o}es entre a
poeira e as radia{\c{c}}{\~o}es s{\~a}o estimadas no
c{\'o}digo radiativo \emph{UKMO}. O ciclo de poeira foi
analisado atrav{\'e}s dos campos m{\'e}dios das emiss{\~o}es,
sedimenta{\c{c}}{\~o}es gravitacionais, deposi{\c{c}}{\~o}es
secas e {\'u}midas, e conte{\'u}dos da poeira transportada. O
balan{\c{c}}o radiativo foi analisado atrav{\'e}s dos campos
incidentes, absorvidos e emitidos das radia{\c{c}}{\~o}es
solares e terrestres. O balan{\c{c}}o de energia foi analisado
atrav{\'e}s dos campos de temperatura e fluxos de calor latente e
sens{\'{\i}}vel. A valida{\c{c}}{\~a}o das
parametriza{\c{c}}{\~o}es da poeira foi realizada atrav{\'e}s
de um estudo de caso, onde os conte{\'u}dos de poeria
transportados foram comparados com dados de sat{\'e}lites e de
superf{\'{\i}}cie, mostrando uma boa concord{\^a}ncia. Os
resultados das simula{\c{c}}{\~o}es mostraram que as
varia{\c{c}}{\~o}es dos conte{\'u}dos de poeira sobre as
regi{\~o}es Orientais e Ocidentais da Amaz{\^o}nia, devido as
emiss{\~o}es remotas e regionais, resfriaram a Amaz{\^o}nia como
um todo, mas reduziram as precipita{\c{c}}{\~o}es somente sobre
a Amaz{\^o}nia Oriental. ABSTRACT: The main objective this work
is to analyze the feedback in energy and radiation budget due the
interactions between dust and radiation over Amazon. Additional
objective is a case study of Caatinga's dust emission to Amazon.
Soil dust are emitted on surface due wind shear and are
transported by the turbulence and advection. During the downstream
transport, dust returns to surface due gravity settling and dry
and wet deposition. Dust loads on atmosphere scattering and
absorbing solar and thermal radiation and modifies both atmosphere
and surface temperature. These interactions changes the energy and
radiation budget and the convection and precipitation supplies.
Dust cycle are parametrized in CCATT model, and dust transport
occurs in CPTEC\${'}\$s AGCM, and dust profiles are coupled in
the UKMO radiative code. Dust cycle are analysed with the averaged
fields of dust emissions, gravity settlings, dry and wet
deposition, and loads. Radiation budget are analyzed with the
incident, absorbed and ernitted solar and thermal fields. Energy
budget are analyzed with the temperature and latent and sensible
heat flux fields. Dust process parametrizations are tested with a
case study where the dust loads are compared with satellite and
surface data, showing good results. Simulations showing that dust
loads transported from remote and regional sources to Amazon
reduces the temperature overall the Amazon and reduced the
precipitation on the Amazon oriental region.",
