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".
