caption_attribution_description: English: The MTSAT satellite on October 27, 2012 captured this infrared satellite image of Typhoon Son-Tinh, at peak intensity, off the southern coast of Hainan island on October 27, 2012, with an 28kilometer wide eye.
context_page_description: This timeline documents all of the events of the 2012 Pacific typhoon season, the period that tropical cyclones formed in the Western Pacific Ocean during 2012. Most of these tropical cyclones formed between May and November 2012. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.
