The Seasons in Taiwan

Taiwan is a place near the equator. It's burning hot in the summer, but windy and cold in the winter. Winters in Taiwan isn't really cold when you look at the temperature, but when you stand at your door, you'll feel the wind that chills your bones. There's usually occasional times where it's warm in the winter, but otherwise, it's mostly windy in Hsinchu, Taiwan. I can't really tell the difference between spring and fall in Taiwan. It looks the same, same traffic and same crazy drivers. But I do have a question about seasons... Why are there so many typhoons in the summer? There weren't ANY typhoons last summer probably because of global warming and weird climate changes, but usually there are a LOT of typhoons in Taiwan's summer, and I really do sometimes wonder WHY... WHY??? WHY??????????
