2005 Pacific typhoon season

The 2005 Pacific typhoon season was the least active typhoon season since 2000, producing 23 named storms, of which 13 became typhoons (including 3 super typhoons). It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2005, though most tropical cyclones typically develop between May and November. The season's first named storm, Kulap, developed on January 13, while the season's last named storm, Bolaven, dissipated on November 20. The season's first typhoon, Haitang, reached typhoon status on July 13, and became the first super typhoon of the year three days later.

The scope of this article is limited to the Pacific Ocean, to the north of the equator between 100°E and the 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones, which can often result in a cyclone having two names, one from the JMA and one from PAGASA. The Japan Meteorological Agency (JMA) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least anywhere in the basin, while the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) are given a number with a "W" suffix.

The 2005 season was a near-average season, the number of typhoons in the year was twenty-three, much less than the average of twenty-seven. The number of typhoons that made landfall in Japan was three, which is almost the average (2.6). In general, this is not a year in which the impact of typhoons has been especially notable. The number of typhoons that passed near Okinawa was eight, which is slightly larger than the average of seven, and this is because this year there are some typhoons moving through the Sakishima Islands towards the Taiwan or China. This year's major typhoons are reviewed below.

Although the season was quiet, some typhoons caused extensive damages in many places, especially in China where eight typhoons struck the country. First, Typhoon Haitang became the strongest storm in the basin this year and caused about $1.1 billion in damages in Taiwan and China in mid July. In August, Typhoon Matsa made landfall in Eastern China and caused about $2.23 billion in damages. Later that same month, two powerful typhoons made landfall, causing extreme damage and some casualties. Similar to Haitang, Typhoon Longwang made landfall in Taiwan and China at a strong intensity causing damages.

Systems

Severe Tropical Storm Kulap

On January 12, a tropical disturbance developed within an area of light vertical wind shear. This allowed deep convection to develop over a broad low-level circulation. The next day, the Joint Typhoon Warning Center (JTWC) issued a Tropical Cyclone Formation Alert (TCFA) as the system continued to develop. Later that day, they issued their first advisory on Tropical Depression 01W while the storm was located about southwest of Chuuk. Several hours later, the Japan Meteorological Agency (JMA) also designated the system as a tropical depression. Early on January 15, the JTWC upgraded 01W to a tropical storm

Typhoon Sonca (Bising)

A large area of convection formed on April 11. Late on April 14, a newly disorganized disturbance formed in that area and steadily intensified. The next two days, the disturbance interacted with another low-pressure area as it moved north towards warm waters. On April 17, the depression weakened due to strong vertical windshear. The JTWC designated as Tropical Depression 03W on April 18. Although the JMA started classifying it as a tropical depression on April 21. It rapidly intensified into a tropical storm, with the JMA naming it Sonca late on April 20. Very early on April 21, the PAGASA classified it as a storm, naming it Bising. Convection built up the storm again on April 22 and entered an area with favorable conditions. The next day, Sonca rapidly intensified into a Category 4 typhoon until it reached peak intensity on mid-April 24. Sonca rapidly weakened due to cool waters and dissipated on April 27.

Tropical Depression Crising

On May 8, a parade of tropical disturbances formed and affected southern Philippines from an ITCZ. As the ITCZ weakened on May 13, the last disturbance formed southeast of Mindanao, Philippines. It moved north until it became a tropical depression on May 16 at 0000 UTC (0800 PHT) east of Surigao on Mindanao Island. It was assigned the name Crising by PAGASA. The storm never organized into a tropical storm and did not receive the more recognized International name for West Pacific storms. The storm drifted northwest then southwest and began losing convection. PAGASA stopped tracking the storm 24 hours later on the 17th at 0000 UTC (0800 PHT) east of Surigao.

Typhoon Nesat (Dante)

A tropical depression formed from a tropical wave late on May 28. It rapidly intensified into Tropical Storm Nesat on May 30, rapidly moving west. This was a powerful storm that formed on May 30 about south-southeast of Guam as Tropical Depression 04W. It was quickly upgraded to Tropical Storm Nesat overnight at 1800 UTC (0200 PHT May 31). Nesat is a Cambodian word for fisherman. On the evening of June 1, it strengthened into Typhoon Nesat. On June 2, it entered the Philippine area of responsibility and was assigned the name Dante for Philippine warnings. Typhoon Nesat (Dante) quickly grew to a Category 4 storm as it approached the Philippines, but it curved away to the northeast and did not pose a threat to land. Waxing and waning in strength it eventually became extratropical southeast of Honshū, Japan at tropical storm strength on the morning of June 10 at 0000 UTC (0900 JST).

Tropical Depression Emong

A large tropical disturbance formed on July 2. The PAGASA issued a tropical depression strength near the Philippines on July 4 at 0600 UTC (1400 PHT) about northeast of Catarman on Samar Island, giving the name Emong. It was assigned the name Emong by PAGASA. The storm never organized into a tropical storm and did not receive the more recognized International name for West Pacific storms. As a poorly organized depression it drifted over Luzon on July 5. Upper-level shear and the depression's landfall caused the storm to lose organization on July 6 while located about south of Hong Kong.

Typhoon Haitang (Feria)

There were 15 deaths in Taiwan and another 14 in mainland China.

Severe Tropical Storm Guchol

Another tropical disturbance formed east of Tropical Depression 11W on August 18. In the same time where 11W became Mawar, the disturbance rapidly intensified into Tropical Depression 12W on the morning of August 20 at 0000 UTC (0900 JST) 190 nautical miles (350 kilometers) southwest of Marcus Island, Japan. It reached Tropical Storm strength the next day and was named Guchol, a Yapese name for the spice turmeric. It reached peak intensity late on August 23. Guchol curved to the northwest and never threatened land. It became extratropical August 25 at 0000 UTC (0900 JST) east-southeast of Nakashibetsu, Hokkaidō, Japan. The remnants of the storm dissipated and crossed the International Date Line on August 27.

Typhoon Mawar

A cluster of thunderstorms began to circulate into a tropical disturbance early on August 18. Its circulation became exposed and intensified again later that day. It became Tropical Depression 11W on the evening of August 19 at 1200 UTC (2100 JST) 245 nautical miles (455 kilometers) southeast of Iwo Jima. The storm intensified rapidly in two days to a Category 4 Super Typhoon but weakened as it approached Japan. Mawar made landfall on Honshū as a Category 2 Typhoon on August 25 at 1800 UTC (August 26 0300 JST) with winds of . After moving inland to the northwest it was downgraded to a Category 1 typhoon before entering the Pacific Ocean. It was downgraded to a Tropical Storm on August 26 and became extratropical on August 27. The extratropical remnants of Mawar dissipated on August 30. One person was killed and seven were injured in relation to Mawar.

Typhoon Talim (Isang)

Tropical Depression 13W formed on the afternoon of August 26 at 0600 UTC northeast of the island of Yap. Within 24 hours it was upgraded to Tropical Storm Talim and the next day became a Typhoon. Talim is a Philippine name for a knife or sharp cutting edge. Typhoon Talim was assigned the name Typhoon Isang for Philippine warnings when it entered the Philippine area of responsibility on August 29. Typhoon Talim (Isang) made landfall at 1800 UTC August 31 (0200 PHT September 1) as a Category 3 storm. Talim dissipated over southeastern China on September 1. Typhoon Talim left at least 110 people dead and 23 missing in Fujian, Zhejiang, Jiangxi & Anhui provinces, with at least 40 people dead in the latter province due to landslides.

There were 167 fatalities in China.

Typhoon Nabi (Jolina)

Typhoon Nabi formed from a tropical depression on the afternoon of August 29 at 0600 UTC (1600 AEST) east of Saipan. 18 hours later it was upgraded to Tropical Storm Nabi. Nabi is a Korean word for a butterfly. It strengthened into a Typhoon on August 30 and passed near the islands of Saipan and Guam on August 31.After passing near the Marianas Islands, the storm continued to strengthen until reaching Category 5 intensity on September 1. Typhoon Nabi was assigned the name Jolina for Philippine warnings when it entered the Philippine area of responsibility on September 3. Typhoon Nabi (Jolina) passed to the east of the island of Okinawa, Japan, and made landfall in the Kagoshima Prefecture of Japan on September 6 as a Category 2 storm. It dissipated shortly after that.

Twenty-one deaths have been reported in Japan. On September 8, five people were missing in South Korea and fifty in Japan as a result of the storm. Japan also reported 143 injured. The storm damaged 10,000 homes in Japan, where 31 of 47 prefectures reported some damage. Eighty-eight roads in Japan were damaged, and 168 landslides were reported there. The heaviest damage was in Miyazaki prefecture on the island of Kyūshū. There were no deaths in the Marianas Islands. Saipan did experience heavy wind gusts of . Guam experienced gale-force wind gusts in addition to approximately of rain.

Typhoon Khanun (Kiko)

Tropical Depression 15W formed from a well-defined low-pressure system located about east of Yap on September 6. It strengthened into a tropical storm later that day. The system was classified as a tropical storm by the Joint Typhoon Warning Center on September 6, while the Japan Meteorological Agency, the agency responsible for naming typhoons, did not upgrade the system until a day later. Tropical Storm 15W entered the Philippine area of responsibility on September 7. It was named Kiko by PAGASA first before being named Khanun by the JMA. Khanun is the Thai name for jackfruit. Typhoon Khanun (Kiko) made landfall in eastern China on September 11 at 0600 UTC (1400 HKT). Khanun dissipated the next day, September 12.

More than 800,000 people were evacuated from their homes as the storm neared. Many people, evacuated by the army, were taken to schools, railway stations, hotels and other solid buildings to take shelter from the approaching storm.

The city of Taizhou, Zhejiang bore the initial brunt of the storm as it was close to where the storm made landfall, 220 km south of Shanghai. Other coastal cities braced for the typhoon as it headed north.Damages totaled to $1.22 billion (2005 USD). There were 25 deaths in China.

At least 16 people are believed to have died in China, and the entire province of Hainan suffered power outages. Damrey then went on to impact Vietnam before losing tropical characteristics while a Tropical Storm. The Joint Typhoon Warning Center ceased advisories with the final one at 0900 UTC September 27 with the system south-southwest of Hanoi, Vietnam.

Typhoon Longwang (Maring)

Tropical Depression 19W formed about south-southeast of Iwo Jima, Japan on September 26. The Joint Typhoon Warning Center initiated a warning for it at 0000 UTC the same day, and was upgraded to Tropical Storm Longwang six hours later. Longwang is Chinese for Dragon King. At 0300 UTC September 27, the Joint Typhoon Warning Center upgraded it to a typhoon. It continued to increase in strength as it tracked west to west-northwest towards Taiwan, and was upgraded to a super typhoon on September 29, acquiring annular characteristics. PAGASA named the storm Maring for Philippine warnings on September 29. Longwang made landfall at 0515 local time on October 2 south of Hualien City, Taiwan as a Category 4 storm. Half a day later, at 2135 local time (1335 UTC), it made second landfall in Fujian Province, China as a minimal typhoon. Longwang dissipated on the next day.

Despite its intensity, Longwang caused mostly property damage, and claimed only one life in Taiwan.

Tropical Depression 20W

The meteorological agencies is now operated of Guangdong and Hainan upgraded a low-pressure center over South China Sea to a tropical depression at 0800 local time, October 6. The Hong Kong Observatory followed suit 30 hours later. The JTWC finally issued a warning for this system at 1500 UTC October 7 (2300 local time), and tropical depression number 20W was issued to the system. The JTWC issued its final advisory on the system just six hours later, west-northwest of Huế, Vietnam. As the system never reached Tropical Storm strength, it was not given a name from the list. The only damage it did, if any, however, was that massive rainfall amounts were recorded – over were recorded in some parts of Hainan.

Typhoon Kirogi (Nando)

A large cluster of thunderstorms formed with convection developed and separated into three low-pressure areas on October 6. But due to warm waters in the western side, two failed to become storms and the Japan Meteorological Agency began issuing warnings for the other disturbance. This disturbance became Tropical Depression 21W while located southeast of Okinawa. At 1200 UTC, October 9 and assigned the name Kirogi to it at 0600 UTC next day. Prior to becoming a Tropical Storm, it entered the Philippine area of responsibility and was assigned the name Nando by PAGASA for Philippine warnings. JTWC finally issued a warning for Kirogi at 0900 UTC, October 10, despite listing it as a Tropical Depression. It was upgraded to a typhoon at 0000 UTC October 12, and reached Category 4 strength about nine hours later. On October 16, Kirogi weakened was it pushes northeast. Kirogi was declared extratropical at 0300 UTC October 19.

Kirogi is a Korean word for a type of migrating bird that lives in North Korea from autumn to spring.

Typhoon Kai-tak

A tropical disturbance developed north of Papua New Guinea on October 20. It entered in an area of favorable environments on October 23, as it slowly intensified. On October 25, it affected the Philippines and rapidly moved to the South China Sea on October 27. The next day, the Japan Meteorological Agency initiated marine warnings for a Tropical Depression. Fifteen hours later, the Joint Typhoon Warning Center issued the number 22W to the system. The next day it was upgraded to Tropical Storm Kai-tak. Kai-tak was a name submitted by Hong Kong in honor of their former airport. On October 30 it was upgraded to a Typhoon. Kai-tak made landfall north of Huế, Vietnam, early on the morning of November 2. At least 19 people were killed and 10 others were left missing in Vietnam. Damages from the storm were estimated to be at least $11 million (2005 USD).

Tropical Storm Tembin (Ondoy)

The Joint Typhoon Warning Center initiated warning for Tropical Depression 23W at 0900 UTC November 7, north-northwest of the Micronesian island of Yap. The storm gained enough power to warrant upgrading to a Tropical Storm 12 hours later. The system entered the Philippine area of responsibility on the morning of November 8 and was named Ondoy by PAGASA. The storm encountered shear as it moved west, and lost organisation on November 8, being downgraded to a tropical depression. On November 9 it regained tropical storm strength and had a better LLCC (low-level circulation centre). On November 10 it was named Tembin by the JMA.

Tembin is a Japanese constellation for the group of stars known in the west as Libra. Tembin then made landfall near midnight November 11 local time in the northern Philippines and lost much of its circulation and convection. Tembin dissipated rapidly the next day.

Severe Tropical Storm Bolaven (Pepeng)

A low-pressure area formed along from the outflow of Tropical Storm Tembin on November 10. The Joint Typhoon Warning Center initiated a TCFA warning for a low-pressure system about west-southwest of Palau late on November 12. This was upgraded to a tropical depression the next afternoon, west of Palau. Forming inside the Philippine area of responsibility it has been named Pepeng by PAGASA. It was named Bolaven on November 16 by the JMA. Bolaven is a Laotian word meaning plateau or mesa. Although it strengthened into a Category 1 typhoon on November 17, it weakened to a tropical storm before making landfall on November 20 at about 800 local time in Cagayan Valley in the northern Philippines. Bolaven rapidly dissipated that same day north of the Philippines on November 21.

Tropical Depression 25W (Quedan)

On December 16, a tropical disturbance developed and was given the name Quedan by PAGASA. Quedan organized into Tropical Depression 25W on December 18 off the northern coast of Borneo. On December 19, the JTWC classified it as a Tropical Storm. The JMA upgraded it to a tropical depression, but they warned it for a brief time. The storm dissipated early on December 20, as wind shear increased on the system.

Storm names

Within the North-western Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names. The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of . While the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N-25°N even if the cyclone has had an international name assigned to it. Names not retired would be used again during the 2009 season. This was the same list used during 2001, except Bising, Dante, Nando, Pepeng, Ramil, Santi, Tino, Undang, Yolanda, Zoraida, Ernie, Florante, Gerardo, Hernan and Jerome, which replaced Barok, Darna, Nanang, Pabling, Roleta, Sibak, Talahib, Ubbeng, Yaning, Zuma, Ekis, Fuerza, Gimbal, Hampas, and Juego. The names Dante, Nando and Pepeng were used for the first time this year; Bising was previously included in the old lists.
