Session Title: Climate Change, Monsoon and Extreme Weather Events
Session Description: The monsoon dominates the socio-economic livelihood over Asia, including the water resources, agriculture and power generation. Therefore the changes and extreme events associated with the global warming is of utmost importance to the lives of over two billion people over the monsoon region. Through observations and modeling, the scientific community has advanced its understanding of the past and future changes of the monsoons. Some of the studies show that the monsoon circulations have intensified, while some other studies suggest the opposite. In the global warming scenario, it is found that the rainfall pattern has undergone substantial changes with tendency for more extremes. Most of the studies stick to the “wet getting wetter and the dry getting drier”, though a few research suggest decrease in rainfall over some of the monsoon regions. The IPCC AR5 is also suggestive of the uncertainties looming over the status and fate of the monsoons.
Monsoonal changes are found to be different when the region and time-periods considered are different – and so are the implications. Thus there is an urgent need to provide more regional-scale information through the use of weather and climate models that could resolve small-scale features. Spatial and temporal changes in temperature, wind and rainfall are vital. This will hopefully provide more information on how climate change will affect the rainfall (monsoon and otherwise), wind and other extreme events, such as warm/cold episodes. In particular the future decision strategies in the renewal energy world must be designed to take into account of the uncertainties and probabilities of weather and climate. This session is setup to bring forth the uncertainties and new understandings regarding large scale and regional changes over the monsoon regions. All climate change studies, past and future, related to the monsoon and associated extreme events, are invited.
