                Abstract

                The El Niño is one of the most powerful climate variation phenomena and has profound impacts throughout the Asian-Pacific region. Extensive research since the 1970s has produced theoretical frameworks capable of explaining the observed properties and impacts of El Niño as well as predictive models. However, the properties and impacts of the El Niño events observed so far in the 21st century have been noticeably different from those observed in the 20th century. These discrepancies have motivated the research community to revise conventional views of the El Niño.

                The changes include shifting the El Niño location from the tropical eastern Pacific to the tropical central Pacific and the El Niño evolution from a single-year pattern to a multi-year pattern. Associated with these changes, the El Niño’s impacts on broad areas of the Asian-Pacific region have become different from those documented during the 20th century. There is substantial evidence that the underlying dynamics of the 21st-century El Niño are also different from those in the 20th century, making its behavior more difficult to predict. While the 20th-century El Niño dynamics resides mostly within the tropical Pacific, the 21st-century El Niño dynamics invokes more of the subtropical Pacific forcing and inter-basin interactions.

                In the talk, I will discuss the views that I have developed during the past decade to explain the changing properties, dynamics, and impacts of the 21st-century El Niño and how they differ from those of the traditional El Niño. Possible reasons for the recent change in the El Niño will also be discussed.

                 

                Bio

                Dr. Jin-Yi Yu is Professor of Earth System Science at the University of California, Irvine, USA. He received his Ph.D. from the University of Washington, and performed postdoctoral research at the University of California, Los Angeles. Dr. Yu's research expertise is in climate modeling, dynamics, and diagnosis. His research work covers a wide range of issues, from global-scale climate changes in the coupled atmosphere-ocean system to regional-scale variations in the Asian and North American monsoons. In recent years, his research has focused on El Nino complexity and inter-basin interactions among the Pacific, Atlantic, and Indian Oceans.
