Tropical cyclones in 2001

During 2001, tropical cyclones formed in seven different areas called basins, located within various parts of the Atlantic, Pacific and Indian Oceans. A total of 128 tropical cyclones formed within bodies of water known as tropical cyclone basins, with 83 of them were further named by the responsible weather agencies when they attained maximum sustained winds of 35 knots. Typhoon Faxai is the strongest tropical cyclone throughout the year, peaking with a pressure of 915 hPa and attaining 10-minute sustained winds of 195 km/h. The deadliest tropical cyclone of the year was Lingling in the West Pacific which caused 379 fatalities in total as it struck the Philippines and Vietnam, while the costliest storm of the year was Michelle, with a damage cost of around $2.43 billion as it catastrophically affected the Greater Antilles and the Bahamas in late October. So far, 23 Category 3 tropical cyclones formed, including two Category 5 tropical cyclones formed in the year. The accumulated cyclone energy (ACE) index for the 2001 (seven basins combined), as calculated by Colorado State University was 672.4 units.

Global atmospheric and hydrological conditions
La Niña is a weather pattern that occurs every few years, as a result of complex variations on the ocean temperatures in the equatorial band of the Pacific Ocean. The 1998–2001 La Niña persisted through early 2001, which made the waters of Pacific Ocean, and the Atlantic Ocean warmer than normal.

Global effects
There are a total of 9 tropical cyclone basins, 7 are seasonal and two are non-seasonal, thus all 7 basins except the Mediterranean and South Atlantic are active. In this table, data from all these basins are added.
