Previous issue date: 2017-02-23 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Nos ?ltimos anos o setor Industrial da Cer?mica Vermelha desenvolveu-se
representativamente com a implanta??o de micro e pequenas empresas de Cer?mica por
todo Brasil. N?o houve, no entanto, precau??es quanto ao uso dos recursos naturais
utilizados como fonte de mat?ria prima para a Ind?stria. Desta maneira investigou-se a
respeito de ind?cios de altera??es micrometeorol?gicas associadas ? Ind?stria de Cer?mica
Estrutural nos elementos meteorol?gicos em algumas ?reas do Nordeste do Brasil. Para
verificar se as vari?veis micrometeorol?gicas: precipita??o, evapotranspira??o, radia??o,
velocidade do vento, umidade, e temperatura m?xima e m?nima, referentes ao per?odo de
1980 a 2013, apresentavam tend?ncias, utilizou-se o Teste de Mann Kendall; e para
calcular os ?ndices de extremos clim?ticos utilizou-se o conjunto de dados para ?ndices de
Extremos Clim?ticos - RClimDex. Foram identificados cinco polos, nos quais verificouse
haver tend?ncias negativas para precipita??o, temperatura m?nima, umidade relativa e
vento. E tend?ncias positivas para as vari?veis temperatura m?xima, evapotranspira??o e
radia??o solar. Detectou-se tend?ncia em todos os polos, com exce??o da temperatura
m?nima para o polo P2 (que apresenta maior n?mero de cer?micas). Identificou-se, ainda,
tend?ncia para os ?ndices de extremos clim?ticos de Rx1day, R99p, Txn, Tnx, Tn10p,
Tx10p, Txx e Tnn. Com tend?ncias positivas de extremos de temperatura para os polos
estudados, com exce??o do polo P1 que obteve tend?ncia decrescente, indicando
diminui??o dos valores m?ximos da m?nima; e do polo P2 que n?o apresentou tend?ncia
para a temperatura m?nima e para os ?ndices de Tnn e Tnx e RX5day. Comportamentos
adversos podem estar associados a a??es antr?picas da regi?o, especificamente ? intensa
atividade ceramista. Por?m, n?o se pode afirmar categoricamente, que esse
comportamento est? associado somente as a??es antr?picas, visto que pode estar sob
influ?ncia de diversos agentes do clima. / In recent years the Industrial sector of red ceramic has developed representatively with
the implantation of micro and small Ceramics companies throughout Brazil. There were,
however, no precautions regarding the use of the natural resources used as raw material
source for the Industry. In this way, we investigated the indications of
micrometeorological alterations associated with the Structural Ceramics Industry in the
meteorological elements in some areas of the Northeast of Brazil. In order to verify if the
micrometeorological variables: precipitation, evapotranspiration, radiation, wind speed,
humidity, and maximum and minimum temperature, referring to the period from 1980 to
2013, presented tendencies, the Mann Kendall test was used; And to calculate the indexes
of climatic extremes the Data Set for Indexes of Climatic Extremes - RClimDex was used.
Five poles were identified, in which there were negative trends for precipitation, minimum
temperature, relative humidity and wind. And positive trends for the variables maximum
temperature, evapotranspiration and solar radiation. A tendency was detected at all poles,
with the exception of the minimum temperature for the P2 pole (which has the highest
number of ceramics). A trend was also identified for the indexes of climatic extremes of
Rx1day, R99p, Txn, Tnx, Tn10p, Tx10p, Txx and Tnn. With positive trends of
temperature extremes for the studied poles, with the exception of the pole P1 that obtained
a decreasing tendency, indicating decrease of the maximum values of the minimum; And
the P2 pole which showed no tendency towards the minimum temperature and for the Tnn
and Tnx and RX5day indices. Adverse behaviors may be associated with anthropogenic
actions in the region, specifically intense ceramist activity. However, it can not be said
categorically that this behavior is associated only with anthropic actions, since it may be
under the influence of several agents of the climate.
