The1991 Pacific typhoon season was a slightly above-average season with 29 tropical storms, 17 typhoons and five super typhoons forming. It was quite a catastrophic season –Typhoon Yunya impacted thePhilippines in mid June while in the same time experiencing avolcanic eruption,Typhoon Mireille severely impactingJapan, which became known for being the costliest typhoon on record until it was surpassed byTyphoon Doksuri in 2023, andTropical Storm Thelma on November which became one of the deadliest storms to strike the Philippines, killing at least over 5,000 people. The season was deadliest since1975.

It ran year-round in 1991, although mosttropical cyclones tended to form in the northwestern Pacific Ocean between May and November 1991.[citation needed] These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. However, the first named storm, Sharon, did not develop until. March 8. The last named storm, Zelda, dissipated on December 5.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of theInternational Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see1991 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by theJoint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by thePhilippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

Systems

[edit]

32 tropical cyclones formed this year in the Western Pacific, of which 30 became tropical storms. 17 storms reached typhoon intensity, of which 5 reached super typhoon strength.





Severe Tropical Storm Sharon (Auring)

Category 1 typhoon (SSHWS)
 
DurationMarch 20 – March 27
Peak intensity120 km/h (75 mph)(10-min);
970 hPa (mbar)

On March 17, a cluster of thunderstorms grouped together which formed a low pressure area far east of theMariana islands. The low pressure area rapidly intensified and became a tropical storm 4 days after formation. Favorable conditions allowed the system to continue to intensify into a Category 1 typhoon. High wind shear on March 25 caused the system to weakened, and it transitioned into anextratropical cyclone.

Tropical Storm Vanessa (Bebeng)

[edit]
Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationApril 23 – April 28
Peak intensity85 km/h (50 mph)(10-min);

Category 5 super typhoon (SSHWS)
 
DurationMay 5 – May 17
Peak intensity185 km/h (115 mph)(10-min);
915 hPa (mbar)

On May 3 an area of disturbed area formed south east of theMariana Islands. A day later the system strengthened into a tropical depression, and continued to intensify into typhoon status four days later. The system showedannular characteristics on May 11, showing an axisymmetric shape. Walt reached peak intensity on May 12, before showing a distincteyewall replacement cycle lasting four hours from late May 13 to May 14. When the eyewall replacement cycle was over, a new, larger eye measuring 65 kilometers across formed. Walt soon turned north east, becomingextratropical on May 17, before merging with another extratropical cyclone north east of Japan.

Typhoon Yunya (Diding)

[edit]
Typhoon (JMA)
Category 3 typhoon (SSHWS)
 
DurationJune 12 – June 17
Peak intensity150 km/h (90 mph)(10-min);
950 hPa (mbar)
Main article:Typhoon Yunya (1991)

After a month without any activity in the Western Pacific, a weak tropical depression (with winds of only 10knots) developed just east of thePhilippines and south of the Tropical Upper Tropospheric Trough on June 11. Located in an area of little wind shear, it headed southwestward, developing spiral-band outflow and becoming a tropical storm on the 12th. As a smallcentral dense overcast (CDO) developed over Yunya, it rapidly developed, becoming a typhoon on the 13th as it paralleled the eastern Philippines. The mid-level ridge forced Yunya westward, where it briefly reached a peak intensity of 195 km/h (120 mph) winds on the 14th. Subsequently, the eastward building of the subtropical ridge produced unfavorable vertical wind shear that weakened Yunya to a minimal typhoon before hittingDingalan,Luzon early on the 15th. Yunya left Luzon as a minimal tropical storm atLingayen Gulf. It turned northward due to a break in the ridge, and dissipated on the 17th near southern Taiwan due to the vertical shear.

Yunya would likely have been an uneventful cyclone had it not struck Luzon on the same day as theclimactic eruption of Mount Pinatubo. The ash cloud that normally would have been dispersed across the oceans was redistributed over Luzon by the cyclonic winds of the typhoon, greatly exacerbating the damage caused by the eruption. The water-laden ash fell over the evacuatedClark Air Base, as well as the rest of Luzon, resulting in downed power lines and the collapse of flat-roofed buildings. In some areas it was practically raining mud.

Yunya exited Luzon throughLingayen Gulf as a weak tropical storm and then turned north toward a break in the subtropical ridge. The system continued to weaken due to the strong vertical wind shear. It then brushed the southern coast ofTaiwan as a tropical depression and finally dissipated before it could complete full recurvature into the mid-latitude westerlies. Yunya directly caused one death from the flooding and heavy rainfall it left.[1]

Category 2 typhoon (SSHWS)
 
DurationJuly 21 – July 30
Peak intensity150 km/h (90 mph)(10-min);
940 hPa (mbar)

Typhoon Caitlin developed from a disturbance in the easternCaroline Islands. A tropical depression formed on July 23 as the system moved towards the northwest. Tropical Storm Caitlin was named the on the 24th and was upgraded to a typhoon the next day. Typhoon Caitlin though several hundred miles away increased the monsoonal flow over thePhilippines. Heavy rains caused landslides in theMt. Pinatubo region killing 16 people. As Caitlin turned to the north the storm passed 60 miles (97 km) to the west ofKadena AB,Okinawa at peak intensity of 110 mph. The heavy rains from Caitlin helped to relieve the ongoing drought on the island, one death was reported. Typhoon Caitlin then began to accelerate northwards and passed through theKorea Strait before turning extratropical in theSea of Japan. Heavy flooding in South Korea killed 2 people and caused $4 million in damage.[3]

Tropical Depression Enrique

Tropical Storm Enrique formed in the eastern Pacific basin, where it reached its peak intensity as acategory 1 Hurricane, becomingHurricane Enrique. Enrique lasted for several days drifting north of theHawaiian Islands as a weak system.[4][5][6] As Enrique approached theInternational Dateline, the system started to redevelop. Shortly after crossing the dateline, Enrique became a tropical storm again on August 1. It lasted for less than 24 hours before strong upper-level wind shear dissipated its convection, exposing the cyclone's circulation.[7] No damages or casualties were caused by Enrique.[6][7][8] It is one of only eight tropical cyclones to exist in all threetropical cyclone basins in the Pacific Ocean.[7] The others are1986's Georgette,[9]1994's Li andJohn,1999's Dora,2014's Genevieve,2018's Hector and2023's Dora.

Typhoon Ivy formed from a broad monsoon trough situated nearKosrae in the easternCaroline Islands. A tropical depression formed on September 2 as the system moved towards the northwest, the next day the depression strengthened into Tropical Storm Ivy. Ivy began to rapidly intensify and reached typhoon strength as the storm passed 130 miles (210 km) east ofTinian andSaipan in theNorthern Mariana Islands. On Saipan one drowning death was reported, but only minor damage was reported in the Northern Marianas. Typhoon Ivy continued on a northwesterly path and reached peak strength of 130 mph (210 km/h) on September 7 prior to recurving to the northeast. Ivy paralleled the southeastern Japan coastline and turned extratropical 600 miles (970 km) to the east of Tokyo. As Typhoon Ivy made its closest approach toHonshū, Tokyo and surrounding areas were buffeted by high winds and heavy rains. Over 200 landslides were reported and one person was killed with 4 others missing.[14] Losses totaled to ¥1.6 billion (US$12 million).[15]

Typhoon Kinna formed in a monsoon trough in the westernCaroline Islands. A tropical depression began to organize on September 10 to the west ofGuam, Tropical Storm Kinna was named later the same day. As Kinna moved towards the northwest the storm began to gather strength and reached typhoon intensity on September 12 just prior to turning north threatening Japan. On the 12th Typhoon Kinna made a direct landfall on southernOkinawa Island at peak strength of 105 mph (169 km/h). Kinna maintained peak intensity after recurving to the north-northeast and making landfall onKyūshū Island. Typhoon Kinna's eyewall passed directly overNagasaki andSasebo cities on September 13, both cities reported wind gusts of 115 mph (185 km/h). Kinna continued moving across Japan and became extratropical near the northern coast ofHonshū Island. On Okinawa Kinna dropped more than 8 inches (200 mm) of rain, in Japan most of the damage occurred near Nagasaki. Throughout Japan and Okinawa 9 deaths were attributable to Typhoon Kinna's passage.[14]

Peak intensity185 km/h (115 mph)(10-min);
925 hPa (mbar)
Main article:Typhoon Mireille

On September 13, Tropical Depression 21W developed over the open Western Pacific. It tracked westward under the influence of the Subtropical Ridge, slowly organizing until becoming a tropical storm on the 15th. A small storm, Mireille rapidly became a typhoon on the 16th, but larger Tropical Storm Luke to its north and Typhoon Nat to its west kept Mireille a minimal typhoon. When the other two storms were far enough away, Mireille rapidly intensified, reaching super typhoon strength on the 22nd with a peak of 150 mph (240 km/h) winds. The storm recurved to the northeast, where it slowly weakened until hitting southwestern Japan on the 27th as a 105 mph (169 km/h) typhoon. Mireille continued to the northeast, and became extratropical later that day, after causing 52 casualties and heavy crop damage amounting to $3 billion (1991 USD). The name Mireille was retired after this season and was replaced by Melissa. The Panama flagged vessel MV "Darshan" loaded with cement clinker from Ube, Japan and intended to bound for Kuching, East Malaysia has grounded in the Eastern part of Hime-shima island "Princess Island".[citation needed]

Tropical storm (SSHWS)
 
DurationSeptember 14 – September 19
Peak intensity100 km/h (65 mph)(10-min);
980 hPa (mbar)

Tropical Storm Luke formed from a disturbance that moved through theNorthern Marianas and became a tropical depression on September 14 just to the west of the islands. The depression began to slowly intensify as it moved towards the west-northwest and Tropical Storm Luke was named on September 15. Luke reached peak intensity of 60 mph (97 km/h) prior to recurving to the northeast and weakening due to increased shear. Tropical Storm Luke then paralleled the southeastern Japan coastline, dropping heavy rains. The resulting flooding and landslides killed 8 people and left 10 others missing prior to Luke turning extratropical east of centralHonshū Island.[14]

Typhoon Orchid formed from a broad monsoon trough that moved through theNorthern Marianas and became a tropical depression on October 4 to the west of the islands. The depression moved on a westerly path and strengthened into Tropical Storm Orchid later the same day. Orchid then began to rapidly intensify and reach peak strength on 130 mph (210 km/h) on October 7 prior to turning to the northeast and accelerating. Typhoon Orchid paralleled the southeast coast ofShikoku andHonshū Islands. As Orchid brushed the islands 96 landslides and heavy flooding were reported in and around the Tokyo region, one person was reported killed due to flooding. Though a great distance away the waves from Orchid and Typhoon Pat combined to produce tremendous waves resulting in the deaths of 2 people onGuam.[14]

Main article:Typhoon Ruth (1991)

Super Typhoon Ruth formed from a tropical disturbance the originated betweenChuuk andPohnpei, as the disturbance moved on a westerly path, a tropical depression formed on October 20. Tropical Storm Ruth was named on the 21st as the storm moved to the southwest of Guam and began to steadily intensity. Ruth reached typhoon strength on October 22 and became a super typhoon on the 24th as the storm reached peak intensity of 165 mph (266 km/h). Ruth began to slowly decline in strength as it neared the northernPhilippines. Ruth made landfall on October 27 on northernLuzon Island with winds of 115 mph (185 km/h) before weakening to a tropical storm. Heavy flooding and numerous landslides were reported on Luzon Island as a result 12 people were killed. After departing Luzon Island Ruth recurved south ofTaiwan and dissipated. Heavy seas caused the freighterTung Lung to sink west of Taiwan, all 18 aboard were killed.[14]

A Category 4 Super Typhoon that affected the northern part of the Philippines. During most of Seth's early life, Seth remained a Tropical Storm, until it encountered warmer waters, where it began to reach its peak intensity on November 5. Seth peaked as a strong category 4 storm, but considerably weakened under typhoon strength when it made landfall in the Philippines as a Tropical Storm. After crossing through the Philippines near the end of its life, Seth stalled and dissipated about halfway between the Philippines and mainland Asia. Seth did feature a well defined eye, and struck the same area of the Philippines right after Super Typhoon Ruth did.

Storm names

[edit]
See also:Lists of tropical cyclone names andTropical cyclone naming

During the season 29 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list from mid-1989.

ThePhilippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. Names not retired from this list will be used again in the1995 season. This is the same list used for the1987 season. PAGASA uses its own naming scheme that starts in theFilipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked ingray.

Retirement

[edit]

Due to extensive damage and a high death toll, the JTWC retired the namesMireille andThelma, which were replaced byMelissa andTeresa. Both names were first used in the1994 season. PAGASA also retired the nameUring with similar reasons and was replaced byUlding for the1995 season.
