Steven Businger will give a sense of the past and future climate of Maunakea based on past climate observations and simulations of future weather. To investigate the future weather and future climatic variability of the alpine and subalpine zones of the island of Hawai‘i through the middle of this century, high-resolution simulations of the “Weather Research Forecasting” model were run over the central Pacific using output from a “Global Climate Model.” This approach allows the influence of Hawai‘is high mountains on future weather to be better understood. The results of this modeling study provide guidance for biologists, entomologists and astronomers to evaluate the general impact of climate change on the high altitude ecology of Maunakea and other high mountains in Hawai‘i. Thoughts regarding how to mitigate and plan for a warming climate will also be presented.


Businger is professor and chair of the Department of Atmospheric Sciences at UH 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, and developing a long-range lightning detection network in the Pacific and lightning’s role in the evolution of tropical and extratropical cyclones. 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.

Speaker Series

This talk is part of the Maunakea Speaker Series, a monthly scholar-focused presentation offered as a partnership among the Office of Maunakea Management, UH Hilo’s ‘Imiloa Astronomy Center, and the UH Hilo Department of Physics and 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 UH Hilo.
