Turbulência de Ar Claro no Sudeste do Brasil: Estudo de Casos

Abstract: Resumo Analisa-se a aplicabilidade dos índices clássicos, numericamente modelados, indicadores de condições atmosféricas turbulenta para previsão de turbulência de céu claro (CAT) na região sul do Brasil. Os eventos foram reconstruídos usando 25.465 mensagens de CAT, denominado de AIREP (Air-Report), de 2015 a 2019, e 12.959 observações in-situ da aceleração vertical da gravidade (VRTG) registrados pelas aeronaves de fevereiro de 2018 a dezembro de 2019. Os registros de CAT via VRTG mostraram que os eventos tu… Show more

“…Research related to CAT forecasting in South America is still in its beginning and is limited to the work carried out by Santos and Krapp (2006) and c) the southern cone of Brazil, representing the Flight Information Region (FIR) under Curitiba's responsibility, is signi cantly impacted by CAT, as demonstrated by a study conducted by Gomes et al (2022), utilizing AIREP records between October 2nd, 2015, and June 4th, 2019, and VRTG data collected by LATAM A320 aircraft from 2018 to 2019. The objective is to create a hybrid CAT prediction model by 1) utilizing the output from a numerical atmospheric model (and alternatively in re-analysis data) to identify and extract features (potential predictors) associated with regional atmospheric turbulence stages, and 2) con guring and training machine learning algorithms to predict the presence or absence of CAT in the atmospheric volume embracing the ight route using these de ned predictors.…”
