The 2004 Pacific typhoon season was an extremely active season that featured the second-highest ACE ever recorded in a single season, second only to 1997, which featured 29 named storms, nineteen typhoons, and six 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 2004, though most tropical cyclones typically develop between May and October. The season's first named storm and also the first typhoon, Sudal, developed on April 4, later was reached typhoon status two days later, and became the first super typhoon of the year three days later. The season's last named storm, Noru, dissipated on December 21.
The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.
The 2002 Pacific typhoon season was a slightly above average Pacific typhoon season, producing twenty-six named storms, fifteen becoming typhoons, and eight super typhoons. It had an ACE over 400 units, making it one of the most active seasons worldwide. 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 2002, though most tropical cyclones typically develop between May and October. The season's first named storm, Tapah, developed on January 11, while the season's last named storm, Pongsona, dissipated on December 11. The season's first typhoon, Mitag, reached typhoon status on March 1, and became the first super typhoon of the year four days later.
The 2001 Pacific typhoon season was the fourth and final consecutive year with below-average activity, making it the lowest four-year period of activity since 1976–1979, due to the presence of a strong La Niña that had persisted from 1998 to 2001. However, it was more active than the previous seasons, producing twenty-five named storms, sixteen typhoons and three super typhoons, with a near normal Accumulated Cyclone Energy (ACE) of 307.3 units. It ran year-round in 2001, with most tropical cyclones in the northwestern Pacific Ocean tending between May and November.
The 2000 Pacific typhoon season marked the first year using names contributed by the World Meteorological Organization. It was a rather below-average season, producing a total of 23 tropical storms, 13 typhoons and 4 intense typhoons. The season ran throughout 2000, though typically most tropical cyclones develop between May and October. The season's first named storm, Damrey, developed on May 7, while the season's last named storm, Soulik, dissipated on January 4 of the next year.
The 1998 Pacific typhoon season was at the time the least active Pacific typhoon season on record, until the record was surpassed 12 years later, spawning 16 tropical storms and 8 typhoons. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1998 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint 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 the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
The 1993 Pacific typhoon season was the most active season for the Philippines, seeing a total of 32 storms forming or entering their area of responsibility. Overall, it was an average season, spawning 28 tropical storms, 15 typhoons and three super typhoons. The season had no official bounds; it ran year-round in 1993, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere. This region is referred to as the Northwestern Pacific Basin, accounting for almost one-third of the world's annual tropical cyclones. The term hurricane refers to a tropical cyclone in the northeast Pacific and northern Atlantic. For organizational purposes, the northern Pacific Ocean is divided into three regions: the eastern, central, and western. The Regional Specialized Meteorological Center (RSMC) for tropical cyclone forecasts is in Japan, with other tropical cyclone warning centres for the northwest Pacific in Hawaii, the Philippines, and Hong Kong. Although the RSMC names each system, the main name list itself is coordinated among 18 countries that have territories threatened by typhoons each year.
The 1979 Pacific typhoon season featured the largest and most intense tropical cyclone recorded globally, Typhoon Tip. The season also experienced slightly above-average tropical cyclone activity. The season had no official bounds; it ran year-round in 1979, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The 1967 Pacific typhoon season was one of the most active Pacific typhoon seasons on record, witnessing the formation of 35 tropical storms during the season. It began on January 1, 1967, though most storms usually form between June and December within the basin. The first storm of the season, Ruby, formed on January 28 west of the Philippines. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1967 Pacific hurricane season. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) were given a numerical designation with a "W" suffix, and any storms reaching 1-minute sustained winds of over 40 mph were given a name. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated to provide protection against natural calamities and to ensure the safety, well-being and economic security of all the people, and for the promotion of national progress by undertaking scientific and technological services in meteorology, hydrology, climatology, astronomy and other geophysical sciences. Created on December 8, 1972, by reorganizing the Weather Bureau, PAGASA now serves as one of the Scientific and Technological Services Institutes of the Department of Science and Technology.
The Philippines is a typhoon-prone country, with approximately 20 typhoons entering its area of responsibility each year. Locally known generally as bagyo, typhoons regularly form in the Philippine Sea and less regularly, in the South China Sea, with the months of June to September being the most active, August being the month with the most activity. Each year, at least ten typhoons are expected to hit the island nation, with five expected to be destructive and powerful. In 2013, Time declared the country as the "most exposed country in the world to tropical storms".
The Climate of Cebu is a tropical wet and dry climate. There are two seasons in Cebu - the wet season and the dry season. Cebu has three different climates, based on the distribution of rainfall, with the most prevalent ones being Am and Af and a very minor area of Aw. Based on temperature, the warmest months of the year are March through October; the winter monsoon brings cooler air from November to February. May is the warmest month, and January, the coolest.
The climate of Asia is dry across its southwestern region, with dry across much of the interior. Some of the largest daily temperature ranges on Earth occur in the western part of Asia. The monsoon circulation dominates across the southern and eastern regions, due to the Himalayas forcing the formation of a thermal low which draws in moisture during the summer. The southwestern region of the continent experiences low relief as a result of the subtropical high pressure belt; they are hot in summer, warm to cool in winter, and may snow at higher altitudes. Siberia is one of the coldest places in the Northern Hemisphere, and can act as a source of arctic air mass for North America. The most active place on Earth for tropical cyclone activity lies northeast of the Philippines and south of Japan, and the phase of the El Nino-Southern Oscillation modulates where in Asia landfall is more likely to occur. Many parts of Asia are being impacted by climate change.
Tropical Storm Vongfong affected China after a deadly flood season. The 14th named storm of the 2002 Pacific typhoon season, Vongfong developed as a tropical depression on August 10. Initially it was disorganized due to hostile conditions, and it failed to intensify significantly before crossing the Philippine island of Luzon. There, flooding forced 3,500 people to evacuate their homes. In the Philippines, the storm killed 35 people and caused $3.3 million in damage.
The effects of the 2013 Pacific typhoon season in the Philippines were considered some of the worst in decades. Throughout the year, a series of typhoons impacted the country, with the worst impacts coming from Typhoon Haiyan, especially in death toll, during November.
Typhoon Koppu, known in the Philippines as Super Typhoon Lando, was a powerful and devastating tropical cyclone that struck Luzon in October 2015. It was the twenty-fourth named storm and the fifteenth typhoon of the annual typhoon season. Similar to Goni earlier in the year, Koppu originated from a tropical disturbance east of the Mariana Islands on October 10. Moving briskly west, the system consolidated into a tropical depression the following day and further into a tropical storm on October 13. Situated over the warm waters of the Philippine Sea, Koppu quickly deepened. The storm reached its peak intensity on October 17 with ten-minute sustained winds of 185 km/h (115 mph) according to the Japan Meteorological Agency (JMA). The Joint Typhoon Warning Center assessed Koppu to have been a Category 4-equivalent super typhoon with one-minute sustained winds of 240 km/h (150 mph). The storm subsequently made landfall at this strength near Casiguran, Philippines. Rapid weakening ensued due to interaction with the mountainous terrain of Luzon and the disheveled core of Koppu emerged over the South China Sea on October 19. Unfavorable environmental conditions inhibited reorganization and the system diminished to a tropical depression on October 21.
Typhoon Cary, known as Typhoon Ising in the Philippines, was the second of two tropical cyclones to affect Vietnam in a week. An area of disturbed weather developed southwest of Pohnpei on August 6, 1987. The system initially remained disorganized, but by August 14, Cary had attained tropical storm intensity. After initially moving north-northwest, Cary turned west-northwest, although intensification was slow to occur. On August 15, Cary was upgraded into a typhoon, and on August 17, the typhoon peaked in intensity. Typhoon Cary then made landfall in northern Luzon while at peak intensity. Across the Philippines, 954 houses were damaged and an additional 89 were destroyed, which left 55,567 people, or 13,247 families that were either homeless or otherwise sought shelter. Five people died in the country while damage totaled $5.58 million (1987 USD), including $1.45 million from agriculture and $4.13 million from infrastructure. The storm weakened over land, but re-intensified into a typhoon over the South China Sea. On August 21, Typhoon Cary passed just south of Hainan, where hundreds of homes were damaged but no fatalities occurred, and subsequently entered the Gulf of Tonkin. The storm weakened as it approached Vietnam, and on August 23, the storm dissipated inland over Laos. Across Vietnam, almost 40,000 ha of land were flooded or destroyed. Twenty people were killed and many others were injured.
The Tropical Cyclone Wind Signals are tropical cyclone alert levels issued by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) to areas within the Philippines that may be affected by tropical cyclone winds and their associated hazards.
