Tropical cyclones in 2014

During 2014, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 117 tropical cyclones had formed this year to date. 79 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC). The most active basin in 2014 was the Western Pacific, which documented 23 named systems, while the Eastern Pacific, despite only amounting to 22 named systems, was its basin's most active since 1992. Conversely, both the North Atlantic hurricane and North Indian Ocean cyclone had a below average season numbering 9 and 3, respectively. Activity across the southern hemisphere's three basins—South-West Indian, Australian, and South Pacific—was spread evenly, with each region recording seven named storms apiece. So far, 26 Category 3 tropical cyclones formed, including ten Category 5 tropical cyclones in the year, becoming as the third-most intense tropical cyclone activity on record, only behind with 1997 and 2018. The accumulated cyclone energy (ACE) index for the 2014 (seven basins combined), as calculated by Colorado State University (CSU) was 724 units.

The strongest of these tropical cyclones was Typhoon Vongfong, which strengthened to a minimum barometric pressure of 900 mbar (hPa; 900 mbar) before striking the east coast of Japan. The costliest and deadliest tropical cyclone in 2014 was Typhoon Rammasun, which struck China in July, causing US$8.08 billion in damage. Rammasun killed 222 people; 106 in Philippines, 88 in China and 28 in Vietnam.

Global atmospheric and hydrological conditions
During January 2014, after surveying various climate models, the World Meteorological Organization warned that there was an enhanced possibility of a weak El Niño event happening during 2014. Over the next few months the climate of the Pacific Ocean started to exhibit features that suggested the impending onset of an El Niño event. Over the ocean, these features included: a rapid fall of the sea level in western Micronesia, as well as a large area of enhanced sea surface temperatures that were present at low latitudes near the International Date Line. In the atmosphere these features included persistent westerly winds at equatorial latitudes, which were displaced eastwards towards the Marshall Islands. A large area of atmospheric convection was present at a low latitude near the International Date Line, in association with the development of an unusual amount of early season tropical cyclones near the Marshall Islands. As a result of some of these conditions, an El Niño Watch was issued by the United States Climate Prediction Center (NOAA's CPC) and the International Research Institute for Climate and Society within their March 2014 diagnostic discussion.

Over the next few months, the atmosphere failed to respond in order to reinforce the developing El Niño, with the monsoon trough remaining weak and tropical cyclone activity slowing, while no episodes of strong westerly winds at a low latitude occurred. Some of the oceanic indicators of El Niño also failed to develop further, with a cooling of sea and sub surface temperatures over the tropical Pacific occurring. However, by the end of 2014, several of the El Niño indexes that were used to judge the state of the ENSO state, indicated that weak El Niño conditions had developed over the Pacific Ocean. As a result, a few of the international meteorological agencies, including the Japan Meteorological Agency and the Hong Kong Observatory reported that an El Niño event had developed during 2014, while others such as the Fiji Meteorological Service considered 2014 to be a near miss. At this time it was thought that the ENSO state would continue to hover at the borderline El Niño conditions, before easing back into neutral ENSO conditions.

North Atlantic Ocean
The Atlantic hurricane season officially began on June 1, 2014. It was a below average season in which nine tropical cyclones formed. Eight of the nine designated cyclones attained tropical storm status, the fewest since the 1997 Atlantic hurricane season. Of the eight tropical storms, six reached at least Category 1 hurricane intensity. The 2014 season extended the period without major hurricane landfalls in the United States to nine years, with the last such system being Hurricane Wilma in 2005. The lack of activity was attributed to an atmospheric circulation that favored dry, sinking air over the Atlantic Ocean and strong wind shear over the Caribbean Sea. Additionally, sea surface temperatures were near-average. A few notable events occurred during the season. Arthur made landfall between Cape Lookout and Cape Hatteras as a Category 2 hurricane, becoming the first U.S. landfalling cyclone of that intensity since Hurricane Ike in 2008. Arthur also became the earliest known hurricane to strike the North Carolina coastline on record, doing so on July 4. In October, Fay became the first hurricane to make landfall on Bermuda since Emily in 1987. With Gonzalo striking the island only four days later, 2014 became the first season on record in which more than one hurricane struck Bermuda. Four hurricanes and two tropical storms made landfall during the season and caused 21 deaths and at least $233 million in damage. Hurricane Cristobal also caused fatalities, though it did not strike land.

Tropical cyclogenesis began in early July, with the development of Hurricane Arthur on July 1, ahead of the long-term climatological average of July 9. Early on July 3, the system intensified into a hurricane, preceding the climatological average of August 10. Later that month, a tropical depression developed over the eastern Atlantic, but dissipated after only two days. There were also two tropical cyclones in August, with the development of hurricanes Bertha and Cristobal. Despite being the climatological peak of hurricane season, only two additional systems originated in September – Tropical Storm Dolly and Hurricane Edouard. In October, three storms developed, including hurricane Fay and Gonzalo and Tropical Storm Hanna. The most intense tropical cyclone – Hurricane Gonzalo – peaked with maximum sustained winds of 145 mph on October 16 which is a Category 4 on the Saffir–Simpson hurricane wind scale. It was the first Category 4 hurricane since Hurricane Ophelia in 2011. The final tropical cyclone of the season was Hanna, which dissipated on October 28.

The season's activity was reflected with an Accumulated Cyclone Energy (ACE) rating of 67. This was nearly double that of the previous season, but still well below the 1981–2010 median of 92. The ACE value in October was higher than August and September combined, which has not occurred since 1963.

Eastern & Central Pacific Oceans
The season's first named storm, Amanda, developed on May 23, shortly after the official start to the Pacific hurricane season on May 15. On May 24, the system intensified into a hurricane, transcending the climatological average date of June 26 for the first hurricane. The next day, Amanda attained major hurricane status, over a month sooner than the average date of July 19. Owing to Amanda's extreme intensity the ACE value for May was the highest on record in the East Pacific at 18.6 units, eclipsing the previous record of 17.9 units set in 2001. Hurricane Cristina became the second's major hurricane, the system broke the previous record set by Hurricane Darby in 2010 which reached major status on June 25. However, this record was broken by Hurricane Blanca in 2015 which reached major status on June 3. Through June 14, the seasonal ACE reached its highest level since 1971, when reliable records began, for so early in the season. By the end of June, the ACE total remained at 230% of the normal value, before subsiding to near-average levels to end July. By late July, the basin became rejuvenated, with 3 systems forming during the final 10 days of the month. Activity in August ramped up significantly, with four hurricanes developing during the month, two of which became major hurricanes, excluding Iselle and Genevieve, which formed in July, but became a major hurricane during August. By the end of August, ACE values rose to 60% above the 30-year average.

Continued, though less prolific, activity extended through September with four hurricanes developing that month. ACE values remained 45% above-average by the end of the month. Following the rapid intensification of Hurricane Simon to a Category 3 hurricane during the afternoon of October 4, the 2014 season featured the highest number of major hurricanes in the Eastern Pacific basin since the advent of satellite imagery. With eight such storms east of 140°W, the year tied with the record set in the 1992 season. However, this record was surpassed by the 2015 Pacific hurricane season.

Systems
A total of 114 systems formed globally in 2014 with 71 of them causing significant damage, deaths, and/or setting records for their basin.

January


The month of January was very active with 18 systems, starting with Ian bringing damages in Fiji and Tonga. Adding on, Lingling was the first disturbance in the West Pacific, affecting Philippines. Colin became the strongest tropical cyclone in the month of January this 2014, but it stayed well from land. 14 more disturbances formed on different basins, 6 are named by their respective meteorological agencies.

February


In the month of February, 11 systems formed, of which 6 were named. Typhoon Faxai became the strongest tropical cyclone of the month, affecting the Caroline Islands and the Mariana Islands. Edilson brought considerable damages and heavy rainfall to Mauritius and Réunion, and Guito did the same to Mozambique and Madagascar.

March
In the month of March, 8 systems formed, of which 5 were named. Cyclone Hellen was one of the most powerful tropical cyclones in the Mozambique Channel on record, as well as the most intense of the 2013–14 South-West Indian Ocean cyclone season: however, it made landfall on Madagascar with winds of 110 km/h. In the Australian basin, Cyclone Gillian was the second most powerful cyclone of the 2013–14 Australian region cyclone season and the strongest in the basin in the last four years. 17F, Lusi, Mike, and 21F formed in the South Pacific basin while Caloy formed in the West Pacific basin near the Philippines.

April
In the month of April, 7 systems formed, the second-least active month of this year; however, 5 storms were named. Severe Tropical Cyclone Ita was the strongest tropical cyclone in the Australian region by minimum central pressure since George in 2007, and since Monica in 2006 by wind speed. In the Australian basin, including Ita, 2 more systems formed: Jack and a weak 17U. Ivanoe formed in the South-West Indian Ocean basin, while Peipah (Domeng), a weak tropical depression, and Tapah existed in the West Pacific basin.

May
May was an extremely inactive month worldwide despite an extant El Niño event, with two tropical cyclones forming. One of them was BOB 02, a depression that brought relief to Odisha, which had been suffering from a heat wave that claimed 22 lives. Coastal areas previously reporting temperatures near 40 C fell below 30 C during the system's passage. The other was Amanda, which was the strongest Eastern Pacific tropical cyclone ever recorded in the month of May, and it is also the strongest cyclone of the month with a wind speed of 135 kn and a pressure of 932 hPa.

November
A total of 7 storms formed within the month of November, of which 4 were named. Typhoon Hagupit was the strongest storm of the month and the second-most intense storm of the year, impacting the Philippines a few weeks after Sinlaku affected the Philippines as a tropical depression. Cyclone Qendresa was a rare system that caused damages and 3 deaths in Italy.
