Named sessions, In Honor of Pedro L. Dias and the late Johann Lutjeharms

Pedro L. Silva Dias

Pedro Silva DiasDr. Pedro Silva Dias holds a Bachelor degree in Applied Mathematics (University of São Paulo/USP in 1974), MSc and PhD in Atmospheric Sciences by the Colorado State University in 1977 and 1979, respectively. Professor at the Institute Geophysics and Atmospheric Sciences (IAG/USP) since 1975 and currently serves as Director of the National Laboratory for Scientific Computing in Brazil. Member of the Brazilian Academy of Sciences. Visiting researcher at NCAR and NCEP in the USA in several occasions. Senior researcher of the National Institute for Space Research and head of the Center of Weather Forecasting and Climate Research between 1988 and 1990. President of the Brazilian Meteorological Society between 1992 and 1994 and Science Director of the Society from 2006 to 2008.

Coordinator of the Environmental Area of the Institute of Advanced Studies of the USP from 1996 to 2007. Published about 120 papers, book chapters, mostly in international journals. Advisor of 35 MSc and 25 PhD students. Participated in a large number of WMO committees (CLIVAR/SSG, WGNE, JSC among others) and national/international science panels. A world renowned expert on the role of tropical heat sources and with a wide variety of climate variability and change studies in South America. He served as one of the primary authors of the Contribution of Working Group I report to the Forth Assessment Report of the Intergovernmental Panel on Climate Change reports published in 1995 and 2007.


In Honor of Johann Lutjeharms

Arne BiastochA scientific presentation “On the role of the Agulhas system in ocean circulation and climate” by Dr. Arne Biastoch, Helmholtz Centre for Ocean Research Kiel (GEOMAR), Germany.

Johann Lutjeharms, one of Southern Africa's leading marine scientists and most-known experts on the Agulhas Current, died on Wednesday, 8 June 2011, after a 10-year battle with cancer. He died during the last hour of World Oceans Day at the age of 67.

As an internationally recognized leader in his field he was an "A" rated researcher of the South African National Research Foundation. In April 2011 he received South Africa's highest honor, the Order of Mapungubwe, an award for South Africans who have “accomplished excellence and exceptional achievement to the benefit of South Africa and beyond” – an excellent summary of Lutjeharms' career. For the international science community he served on working groups of the Scientific Committee for Oceanic Research (SCOR), the International Union of Conservation of Nature and Natural Resources (IUCN), and the International Association for the Physical Sciences of the Ocean (IAPSO).

Johann Lutjeharms' main field of investigation was in establishing, quantifying and understanding the large-scale circulation patterns of the oceans adjacent to southern Africa and their influence on weather and climate. In this research he laid grounds for the recognition of the importance of the Agulhas Current system for the global oceanic circulation in the international science community. In the 104-year history of the South African Journal of Science, Johann Lutjeharms was its most published author, as he produced eight books, 32 contributions to books, 177 papers in peer-reviewed international journals, 117 reviews and popular articles, 46 research and technical reports and 14 contract reports. His articles in prestigious journals included two in Science and five in Nature.
