Past and Future Climate on Maunakea

Sep 26, 2017 7:00 PM

A Maunakea Speaker Series presentation by Dr. Steven Businger, University of Hawaiʻi at Mānoa, Department of Atmospheric Sciences

The next scheduled program in the Maunakea Speaker Series will be held Tuesday, September 26th from 7 pm to 8 pm at UH Hilo Science & Technology Building (STB) Room # 108.

Dr. Steven Businger will discuss the climate of Maunakea—past, present, and future—including historic climate observations and simulations of future weather.  Using output from a Global Climate Model, he will share high-resolution "Weather Research Forecasting" simulations for the central Pacific in order to predict future weather and climate variability of the alpine and subalpine zones on Hawaiʻi Island.  This research has enabled better understanding of the influence that Hawaiʻi's high mountains are likely to have on future weather, while providing direction for biologists, entomologists, and astronomers in evaluating the impacts of climate change on the high-altitude ecology of Maunakea and other high mountains in Hawaiʻi.  Dr. Businger will also share thoughts on how we might mitigate and plan for a warming climate to come.

Dr. Steven Businger is Professor and Chair of the Department of Atmospheric Sciences at the University of Hawaiʻi at Mānoa and was elected Fellow of the American Meteorological Society (AMS) in 2010.  His areas of expertise include understanding of cyclogenesis in cold air streams and in the subtropics (e.g., kona lows and tropical cyclones), using ground-based GPS receivers for estimating atmospheric precipitable water, the Vog Measurement and Prediction Project (VMAP) for providing real-time vog forecasts, and developing a long-range lightning detection network in the Pacific and lightning's role in the evolution of tropical and extratropical cyclones.  Dr. Businger also established the Mauna Kea Weather Center which, in addition to providing regular forecasts, has fostered progress in the multidisciplinary problem of modeling atmospheric optical turbulence over complex terrain in support of the astronomy community. 

The Maunakea Speaker Series is free and open to the public. On-campus parking is open and available without charge after 4:00 pm.


About the Maunakea Speaker Series

The Maunakea Speaker Series is a monthly scholar-focused presentation offered as a partnership among the Office of Maunakea Management, 'Imiloa Astronomy Center, and the University of Hawai'i at Hilo Department of Physics & Astronomy. This collaborative venture gives the community unprecedented access to fascinating research taking place on Maunakea and other topics unique to the Island of Hawai'i. A venue for scholars to share their stories and learn from discussion, the series promotes understanding and collaboration across all sectors of the community, while addressing the goals of the University of Hawai'i at Hilo.
