Stephen K. Boss, professor of environmental dynamics and sustainability in the Fulbright College of Arts and Sciences at the University of Arkansas, launched the Coastlines & People (CoPe) Virtual Symposium Project on September 14, 2022. Boss presented “Far-Field Effects of Sea-Level Rise and Ocean-Climate Processes on the Heartland: An Overview.” This project was cosponsored by the David and Barbara Pryor Center for Arkansas Oral and Visual History in Fulbright College.
The third presentation entitled "Using the Köppen-Geiger Climate Classification to Model Environmental Realms: Implications for Coastal Areas" was delivered on September 28, 2022, by Timothy P. Eichler, an atmospheric scientist with NOAA’s Climate Prediction Center.
Eichler joined NOAA after working at the University of Arkansas. He received his Ph.D. in Atmospheric Science from Columbia University in New York. Eichler’s research focuses on the role of mid-latitude storm tracks in current and future climate, a topic for which he has produced numerous publications. Eichler has taught many courses in meteorology and climatology, and was awarded the William V. Stauder, S.J. Award for Excellence in Undergraduate Teaching in the Natural Sciences when employed at Saint Louis University. Eichler has presented at many conferences and helped organize NOAA’s Climate Diagnostic Workshop in St. Louis, Missouri.

Using the Köppen-Geiger Climate Classification to Model Past, Present, and Future Environmental Realms
Climate classification systems can be useful tools for relating atmospheric processes and impacts to other environmental features, including those that occur in coastal areas and impact people. The Köppen-Geiger (KG) classification system has been used for such purposes for over a century and has been modified several times, with the goal of conforming boundaries of climatic types to the realms of biomes. The availability of global, gridded data sets, including over marine areas, for several decades has allowed for the algorithms used to categorize KG climate types to be extended to the marine earth, thereby giving a truer global picture of the extent of various climate types and how they have changed over time. This development is particularly important in coastal areas, because the generation of types over the entire planet no longer leaves coastal areas on the fringe of the spatially interpolated KG type maps, likely enhancing accuracy. This presentation summarizes recent research that maps the KG system over the oceans, compares terrestrial vs. marine extents of the KG types, re-evaluates the extent to which the types correspond to biomes and soil orders over the terrestrial Earth, compares the extent of KG types today to those that may have existed at the time of the Last Glacial Maximum and mid-Holocene, and offers an approach for improving ensemble forecasts of KG types.
Dr. Robert V. Rohli holds a B.A. summa cum laude in geography from the University of New Orleans, an M.S. in atmospheric sciences from The Ohio State University, and a Ph.D. in geography from Louisiana State University. From 2006-2018, he served as faculty director of the LSU Residential Colleges Program at Louisiana State University. His teaching and research interests are in atmosphere circulation variability; synoptic, coastal, and hazard meteorology/climatology; hydrometeorology; geoscience education; history of science; metacognition; and living-learning communities.
