A Seminar on:
Subtropical East Asia Hydroclimatic Changes: History, Laws, and Mechanisms
The subtropical east Asia is one of the world’s most populated regions, thus understanding the response of precipitation to changes in climate forcing is crucial for predicting future water availability. Changes in precipitation over Asia monsoon areas have been generally assumed to be controlled by changes in boreal summer solar insolation. However, the recent years have witnessed increasing lines of evidence questioning the notion of a uniformly direct response of Asia monsoon precipitation to changes in boreal summer solar insolation. Over the subtropical East Asia areas, there prevails different atmospheric circulations, including Indian summer monsoon, East Asia summer monsoon, ITCZ, and western Pacific subtropical high. How hydroclimate changes over there? What are the driving forcings behind? How will the water availability change in a global warming scenario? These are frontier questions both in climatology and paleo- climatology. This seminar will focus on these scientific issues, with presentations and discussions covering historical hydroclimatic records, climatic simulations, geochemical methods and techniques, etc.
