The ATTO Micrometeorological Intercomparison Experiment (ATMIX)

Autor: Luca Mortarini, Nelson Dias, Cleo Quaresma Dias, Daiane Brondani, Otavio Acevedo, Antônio Manzi, Pablo de Oliveira, Anywhere Tsokankunku, Fernando Rossato, Alessandro Araújo, Mathias Soergel, Carlos Alberto Nobre Quesada

A central constituent of the ATTO project is the deployment of an array of sonic anemometers to measure vertical profiles of means and second-order moments of the wind velocity vector. The two instruments used are the Campbell Scientific Instruments

Publikováno v: Atmosphere, Vol 14, Iss 1, p 64 (2022)

This study investigates a summer heat wave (HW) associated with downslope winds (DWs) affecting the central region of the state of Rio Grande do Sul (RS), Brazil. The temporal evolution of both phenomena is analyzed in the atmospheric boundary layer

The Detection, Genesis, and Modeling of Turbulence Intermittency in the Stable Atmospheric Surface Layer

Autor: Mohammad Allouche, Elie Bou-Zeid, Cedrick Ansorge, Gabriel G. Katul, Marcelo Chamecki, Otavio Acevedo, Sham Thanekar, Jose D. Fuentes

Publikováno v: Journal of the Atmospheric Sciences

Intermittent transitions between turbulent and nonturbulent states are ubiquitous in the stable atmospheric surface layer (ASL). Data from two field experiments in Utqiaġvik, Alaska, and from direct numerical simulations are used to probe these stat

Estudo do escoamento turbulento atmosférico utilizando ensaios em túnel de vento e simulação numérica

Autor: Daniel Schuch, Edson R. Marciotto, Otávio Acevedo, Gilberto Fisch, Ana Cristina Avelar

Publikováno v: Revista Brasileira de Meteorologia, Vol 29, Iss 3, Pp 338-350 (2014)

A estrutura do campo de vento e da turbulência atmosférica gerada no interior de uma cavidade rasa é analisada com o uso de ensaios realizados em túnel de vento e simulação numérica com um modelo bidimensional de grandes turbilhões (LES). As
