Summary: The planetary boundary layer (PBL) structure is investigated focusing on days with low-tropospheric ducts occurrence in the Petrolina-PE region, in the period from 1 to 29 April 2014. Ducts identification and the estimative of the PBL top/height and its dynamic and thermodynamic characterization is based on 12 UTC upper-air soundings launched at the altitude station of Petrolina. Surface ducts are associated with high instability and wind speed intensification in the surface layer. Ducts at the PBL top (elevated ducts) are associated with a decrease in the moisture content of the air and a wind speed maximum, above the PBL, in the low-troposphere.

A identificação dos dutos e a estimativa do topo/altura da CLP e sua caracterização dinâmica e termodinâmica está fundamentada em dados de sondagens de ar superior realizadas às 12 UTC na estação de altitude de Petrolina. Os dutos de superfície estão associados com alta instabilidade e aumento da intensidade do vento na camada superficial. Os dutos no topo da CLP (dutos elevados) estão associados com uma redução do teor de umidade do ar e um máximo da intensidade do vento, acima da camada, na baixa troposfera.Universidade Federal de Santa Maria2016-07-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaenatura/article/view/2024310.5902/2179460X20243Ciência e Natura; Vol. 38 (2016): SPECIAL EDITION: IX WORKSHOP BRASILEIRO DE MICROMETEOROLOGIA; 318-325Ciência e Natura; v. 38 (2016): EDIÇÃO ESPECIAL: IX WORKSHOP BRASILEIRO DE MICROMETEOROLOGIA; 318-3252179-460X0100-8307reponame:Revista Ciência e Natura (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaenatura/article/view/20243/pdfCopyright (c) 2016 Ciência e Naturainfo:eu-repo/semantics/openAccessSousa, Leandro Fontes deCorreia, Magaly de FatimaAragão, Maria Regina da SilvaRibeiro, Roberta Everllyn Pereira2022-10-14T13:33:33Zoai:ojs.pkp.sfu.ca:article/20243Revistahttps://periodicos.ufsm.br/cienciaenatura/indexPUBhttps://periodicos.ufsm.br/cienciaenatura/oaicienciaenatura@ufsm.br || centraldeperiodicos@ufsm.br2179-460X0100-8307opendoar:2022-10-14T13:33:33Revista Ciência e Natura (Online) - Universidade Federal de Santa Maria (UFSM)false
