The Vecchi Research Group focuses on climate science and extreme weather events, hurricanes, mechanisms of precipitation variability and change, ocean-atmosphere interaction, and detection and attribution. Their research topics are listed below. The faculty lead is Gabriel Vecchi, Professor of Geosciences at the Department of Geosciences. Gabriel Vecchi is also the director of High Meadows Environmental Institute (HMEI), he is co-director the Cooperative Institute for Modeling the Earth System, a collaboration between Princeton and the Geophysical Fluid Dynamics Laboratory. Vecchi is director of HMEI’s Climate and Energy Challenge as well. Climate impacts from large volcanic eruptions. Tropical cyclone sensitivity to radiative forcings in a range of climate models. Impact of climate on tropical infectious disease. Tropical cyclone variability over the last millennium. Impact of sea surface salinity on tropical cyclones over the Indian Ocean. Impact of tropical cyclones on regional extreme weather and climate. Heat waves and climate. Dynamics of El Niño and the monsoons. Climate feedbacks and sensitivity.
