# Tropical cyclones in 1992

The year 1992 featured the highest amount of accumulated cyclone energy (ACE) on record, with an ACE rating of 1,163.1 units. It would be regarded as one of the most intense tropical cyclone years on record. Throughout the year, 111 tropical cyclones formed, of which 101 were given names by various weather agencies. Five Category 5 tropical cyclones would form in 1992.
Tropical cyclones are primarily monitored by a group of ten warning centers, which have been designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization. These are the United States National Hurricane Center (NHC) and Central Pacific Hurricane Center, the Japan Meteorological Agency (JMA), the India Meteorological Department (IMD), Météo-France, Indonesia's Badan Meteorologi, Klimatologi, dan Geofisika, the Australian Bureau of Meteorology (BOM), Papua New Guinea's National Weather Service, the Fiji Meteorological Service (FMS) as well as New Zealand's MetService. Other notable warning centres include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the United States Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

## Systems
### January

In January, the Intertropical Convergence Zone (ITCZ), which allows for the formation of tropical waves, is located in the Southern Hemisphere, remaining there until May. This limits Northern Hemisphere cyclone formation to comparatively rare non-tropical sources. In addition, the month's climate is also an important factor. In the Southern Hemisphere basins, January, at the height of the austral summer, is the most active month by cumulative number of storms since records began. Of the four Northern Hemisphere basins, none is very active in January, as the month is during the winter, but the most active basin is the Western Pacific, which occasionally sees weak tropical storms form during the month. January was mildly active, with six tropical cyclones forming, while four were named.
Tropical Storm Bryna from the South-West Indian Ocean persisted into 1992 and made landfall in Madagascar, dropping heavy rainfall and causing some damage and two deaths in Mahajanga. The year began with the formation of Severe Tropical Storm Axel in the Western Pacific Ocean on January 4. During its journey at sea, Axel caused havoc on some islands such as the Marshall Islands, Caroline Islands, and Mariana Islands in the Federated States of Micronesia; at least $1 million in damages occurred.

### February

In terms of activity, February is normally similar to January, with activity effectively restricted to the Southern Hemisphere excepting the rare Western Pacific storm. In fact, in the Southern Hemisphere, due to the monsoon being at its height, February tends to see more formation of strong tropical cyclones than January despite seeing marginally fewer overall storms. In the Northern Hemisphere, February is the least active month, with no Eastern or Central Pacific tropical cyclones and only one Atlantic tropical cyclone having ever formed in the month. Even in the Western Pacific, February activity is low: in 1992, the month had never seen a typhoon-strength storm, the first being Typhoon Higos in 2015. February 1992 was the record-breaking most active month ever recorded in the history of worldwide tropical cyclogenesis with twelve systems forming and ten storms getting named.

### March

During March, activity tends to be lower than in preceding months. In the Southern Hemisphere, the peak of the season has normally already passed, and the monsoon has begun to weaken, decreasing cyclonic activity, however, the month often sees more intense tropical cyclones than January or February. Meanwhile, in the Northern Hemisphere basins, sea surface temperatures are still far too low to normally support tropical cyclogenesis. The exception is the Western Pacific, which usually sees its first storm, often a weak depression, at some point between January and April.
In 1992, a total of four systems formed during March, all of them intensified into tropical storms. The most intense storm of the month was Cyclone Fran, which formed in the South Pacific Ocean on 4 March. It intensified to attain a pressure of 920 hPa (27.17 inHg), making Fran the most intense storm thus far in the year. In late March, meteorological conditions similar to what allowed Ekeka to develop persisted in the central Pacific. An area of convection organized into Tropical Depression Two-C, just north of 5˚N, atypically close to the equator, and far to the southwest of Hawaii. Moving west-northwestward, it slowly intensified, intensifying into a tropical storm on March 29. Upon doing so, the CPHC gave it the name Hali. Later that day, the storm attained peak winds of 50 mph (80 km/h), before increased southwesterly wind shear imparted weakening. Hali was downgraded to a tropical depression on March 30, and it dissipated shortly thereafter. It never affected land.

### April

The factors that begin to inhibit Southern Hemisphere cyclone formation in March are even more pronounced in April, with the average number of storms formed being hardly half that of March. However, even this limited activity exceeds the activity in the Northern Hemisphere, which is rare, with the exception of the Western Pacific basin. All Pacific typhoon seasons between 1998 and 2016 saw activity between January and April, although many of these seasons saw only weak tropical depressions. By contrast, only two Atlantic hurricane seasons during those years saw tropical cyclone formation during that period. With the combination of the decreasing temperatures in the Southern Hemisphere and the still-low temperatures in the Northern Hemisphere, April and May tend to be the least active months worldwide for tropical cyclone formation.
April 1992 was an example of this phenomenon, with only five tropical cyclones forming, and only three becoming tropical storms, making the month the second-least active of 1992. Of those two storms, the stronger was Tropical Cyclone Jane-Irna, which formed in the Australian region on 8 April and crossed over to the South-West Indian Ocean before dissipating on 14 April. Tropical cyclogenesis in the annual Atlantic hurricane season began with the development of Subtropical Storm One on April 21.

### May

Around the middle of May, the Intertropical Convergence Zone (ITCZ), which allows for the formation of tropical waves and has previously remained in the Southern Hemisphere for the first five months of the year, moves to the Northern Hemisphere, allowing the northern cyclone seasons to start in earnest. Without the presence of the ITCZ, Southern Hemisphere cyclones must form from non-wave sources, which are rarer. For that reason, cyclone formation is relatively sparse, with May tending to be the month of the final storm in each of the three basins. Meanwhile, more intense storms are nearly unheard of, with the South-West Indian Ocean having seen only one intense tropical cyclone and no very intense tropical cyclones in the month, and the other two basins having similar levels of activity in May. In the Northern Hemisphere, May is the first month most basins see activity, due to the new presence of the ITCZ. The Pacific hurricane season begins on May 15, and although the Atlantic hurricane season officially begins on June 1, off-season storms are very common, with over half of the 21st century seasons seeing a storm form in May. Although the North Indian Ocean has no official start or end date, due to the monsoon, mid-May is the beginning of a month-long period of high activity in the basin. Even in the Western Pacific, activity tends to increase throughout May.
May 1992 was the record-breaking least active month ever recorded in the history of worldwide tropical cyclogenesis with only one tropical cyclone within the month – BOB 01 – the first cyclonic storm of the 1992 North Indian Ocean cyclone season. Although Tropical Cyclone Innis was active in the month, it was counted for the month of April, as that was the month it formed in.

### June

June was active, with ten tropical cyclones forming, while six were named. Tropical Storm Agatha in the eastern Pacific Ocean killed 10 people in southwestern Mexico. Typhoon Bobbie, alongside with Typhoon Chuck in the western Pacific Ocean caused heavy rains and mudslides on the northern Philippine islands, causing $27.2 million in damage

### July

July was very active, with sixteen tropical cyclones forming, while twelve were named. Hurricane Darby claimed three lives in its path.

### December
