With the passage of Haiyan, an immense storm for such a southerly latitude, and the very active WPac year we have seen, I was looking for historical references. I came across this paper on typhoons in China, it is relevant to this topic because of the references to the dates of greatest activity. Could there be any link with current low SSN and hyperactivity in the basin. I wonder if any of you have institutional access to the paper and could comment on the findings. http://onlinelibrary.wiley.com/doi/10.1111/0004-5608.00253/abstract
