The 2009 ICTP Prize in honour of Edward Norton Lorenz has been awarded to Professor Marcelo Barreiro. He is currently associate professor and head of the Atmospheric Sciences Unit, School of Sciences, Universidad de la República, Montevideo, Uruguay.

The ICTP Prize recognises Barreiro’s “contributions in the field of tropical Atlantic variability, and the exploration of dynamical mechanisms to explain the paleo-climatic record in the last few million years”. The results of his investigations have important implications for seasonal forecasting and the climate change debate.

Barreiro has been a speaker at ICTP training activities in the field of the physics of weather and climate since 2005.

The ICTP Prize, created in 1982 by the ICTP Scientific Council, is awarded to researchers for outstanding and original contributions in physics and mathematics.
