Hendrik (Henk) Tennekes (born December 13, 1936, Kampen) was the director of research at the Royal Dutch Meteorological Institute (Koninklijk Nederlands Meteorologisch Instituut, or KNMI), and was a Professor of Aeronautical Engineering at Pennsylvania State University. He is known for his work in the fields of turbulence and multi-modal forecasting. He authored the textbooks The Simple Science of Flight: From Insects to Jumbo Jets and A First Course in Turbulence with John L. Lumley. The book "A First Course in Turbulence", is a classic that logs more than 2,000 citations on Google Scholar.
He was a member of the 'Royal Netherlands Academy of Arts and Sciences' (Koninklijke Nederlandse Akademie van Wetenschappen, KNAW) from 1982 - 2010.
In an interview in the Dutch paper De Telegraaf, Tennekes says he was ousted from his position at the Royal Dutch Meteorological Institute due to his skepticism over climate change. After publishing a column critical of climate model accuracy, Tennekes says he was told "within two years, you'll be out on the street".
According to Gerbrand Komen, retired director "Climate Research and Seismology" at the KNMI, Tennekes' view on climate change played a minor role. More important were Tennekes' personality making it impossible to work with him, and his solitary views on a broad range of subjects. As an example Komen recalls how Tennekes objected to the increase of computing power for medium-range weather forecasting, because Tennekes' considered improved forecasting unnecessary. According to Komen, Tennekes supported this decision by referring to biblical texts.
