@gansub your answers are generally excellent, and it looks like you're likely to nail it with all that! Everybody can votes on answers (SE's main feedback on answer quality) the only thing the OP holds is the "accept" button and one vote, plus (as in this case) the occasional bounty. I can't *pre-accept* an unwritten answer nor *pre-award* a bounty, and since the bounty just started there is always the chance of other answers in the next seven days plus one day grace period. These are just the realities of Stack Exchange.

@gansub but in my experience a really good answer (which it looks like you've got) *generally* "passes". :-)

[A 300-Year Typhoon Record in Taiwan and the Relationship with Solar Activity](http://tao.cgu.org.tw/index.php/articles/archive/atmospheric-science/item/1171) (also [here](http://140.112.66.168/tao/media/k2/attachments/v244-IIp737.pdf)) shows that about 30% of all typhoons in the western north pacific (WNP) affect Taiwan. (Author's [home page](http://www1.geo.ntnu.edu.tw/%7Ecwhung/))

I'm not sure how "affect" is defined there, but there are certainly a lot of them, and Taiwan depends on them. This spring there is a serious shortage of water in reservoirs **due to an inadequate number of typhoons in the last year or two.**

**Question:** Why do 30% of all typhoons in the western north pacific (WNP) affect Taiwan? What is it that seems to focus typhoons towards Taiwan?
