The 2013 Outstanding Student Poster (OSP) Award is awarded to Joyce Bosmans for the poster/PICO entitled:

Obliquity signals at low latitudes (Bosmans, J.; Lourens, L.; Hilgen, F.)

Joyce Bosmans is a PhD student at the Faculty of Geosciences at the University of Utrecht, as well as the Royal Netherlands Meteorological Institute (KNMI), the Netherlands. She investigates how changes in the Earth’s orbit affect climate, specifically low-latitude climate. Using a high-resolution general circulation model, EC-Earth, she performed experiments of Mid-Holocene as well as extreme precession and obliquity orbital forcing (i.e. changes in the distribution of insolation). The EGU 2013 poster on “Obliquity signals at low latitudes” focusses on a direct mechanism through which obliquity changes can affect low-latitude climate, namely the summer inter-tropical insolation gradient. This work shows that obliquity, which has very little direct effect on low-latitude insolation, can affect low-latitude climate without high-latitude influence.
