Miguel Teixeira

About

Miguel Teixeira obtained his Licenciate degree in Geophysical Sciences (Meteorology) from the Faculty of Sciences of the University of Lisbon (FCUL). He obtained his Doctorate degree in Meteorology from the University of Reading, United Kingdom. Afterwards, Miguel Teixeira was, first a Postdoctoral Research Assistant, and then a Research Fellow, at the Geophysics Centre of the University of Lisbon (CGUL), now Instituto Dom Luiz (IDL) (Associate Laboratory).

More recently, Miguel Teixeira was a Lecturer at the Department of Meteorology, University of Reading, before joining the Fluids Section of the Department of Mechanical Engineering of FEUP, University of Porto. Miguel Teixeira has been using mostly theory, namely asymptotic methods and linear theory, to study a range of problems of geophysical turbulence and stratified flows in the atmosphere and oceans, in collaboration with numerical modellers. He has modelled turbulence using Rapid Distortion Theory, and stratified flows over mountains, more specifically mountain waves, using wave theory. He has evaluated the drag force produced by gravity waves in flows over orography, taking into account various atmospheric effects, with the aim of improving parametrizations of this unresolved force in weather prediction and climate models.

Miguel Teixeira has worked in Portugal and the United Kingdom, but has had collaborations that led to academic visits to Austria and Croatia. He has published around 60 papers in peer-reviewed scientific journals, such as Journal of the Atmospheric Sciences, Quarterly Journal of the Royal Meteorological Society, Journal of Fluid Mechanics and Physics of Fluids. He has led 5 competitively funded research projects and was a research team member in 9 projects, and has served as referee for numerous scientific journals in meteorology, physical oceanography and fluid mechanics, as well as evaluator for research projects funded by international agencies, including the National Science Foundation (USA) and the European Research Council (EU).
