1977 Global Tropical Cyclones Outside the Northwest Pacific

Included in this database in 1977 73 Tropical cyclones outside the Northwest Pacific: 17 in the South Indian Ocean, 18 in the South Pacific, 6 in the North Indian Ocean, 17 in the East Pacific, and 15 in the North Atlantic. Strongest of the year: Hurricane Anita (about 77.2 m/s). For Northwest Pacific typhoons, see 1977 Typhoon .

Data reliability:
● ReliableWeather satellites monitored these systems throughout, resulting in relatively accurate tracks and intensities (Atlantic and Eastern Pacific from 1966; other basins from 1980)
● Generally reliableAircraft entered typhoons for direct measurements, but satellites were not yet widespread: tracks are generally accurate, while intensities may be biased and weaker cyclones may be missing (from 1950 until satellite coverage became widespread)
● Inferred dataWith no satellites or aircraft that year, intensities were retrospectively estimated from records from ships and coastal weather stations (before 1950)
● Track onlyOnly approximate positions are available, with no wind speed or pressure records, so they are excluded from intensity rankings (mostly early records from the Indian Ocean and Southern Hemisphere)
