Tropical cyclones in 2011 were spread out across seven different areas called basins; the strongest tropical cyclone was Typhoon Songda strengthened to a minimum barometric pressure of 920 mbar (hPa; 27.17 inHg) before striking South Korea. 135 tropical cyclones had formed this year to date. 74 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC).
Tropical cyclone activity in each basin is under the authority of an RSMC. The National Hurricane Center (NHC) is responsible for tropical cyclones in the North Atlantic and East Pacific. The Central Pacific Hurricane Center (CPHC) is responsible for tropical cyclones in the Central Pacific. Both the NHC and CPHC are subdivisions of the National Weather Service. Activity in the West Pacific is monitored by the Japan Meteorological Agency (JMA). Systems in the North Indian Ocean are monitored by the Indian Meteorological Department (IMD). The Météo-France located in Réunion (MFR) monitors tropical activity in the South-West Indian Ocean. The Australian region is monitored by five TCWCs that are under the coordination of the Australian Bureau of Meteorology (BOM). Similarly, the South Pacific is monitored by both the Fiji Meteorological Service (FMS) and the Meteorological Service of New Zealand Limited. Other, unofficial agencies that provide additional guidance in tropical cyclone monitoring include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the Joint Typhoon Warning Center (JTWC).
Global atmospheric and hydrological conditions
editNorth Atlantic Ocean
editThe Atlantic Ocean began an organization favorable to the sea surface temperatures due to 2010-12 La Niña event. The Northern Hemisphere, nineteen tropical cyclones formed in the Atlantic hurricane season, the third-most active in history with previous 1887, 1995, 2010 and 2012 seasons.
Eastern Pacific Ocean
editThe Eastern and Central Pacific Ocean began an unfavorable conditions due to 2010-12 La Niña event. During the month of June to November along the Pacific hurricane season they a favorable organization began due to the sea surface temperatures and the formation of El Niño–Southern Oscillation. The season concluded a total of eleven named storms, ten hurricanes and six major hurricanes from the season, classified as below-normal average season.

edit1 Only systems that formed either on or after January 1, 2011 are counted in the seasonal totals.
2 Only systems that formed either before or on December 31, 2011 are counted in the seasonal totals.
3 The wind speeds for this tropical cyclone/basin are based on the IMD Scale which uses 3-minute sustained winds.
4 The wind speeds for this tropical cyclone/basin are based on the Saffir Simpson Scale which uses 1-minute sustained winds.
5The wind speeds for this tropical cyclone are based on Météo-France which uses gust winds.
