JMA data: 60kt? Casualties: the naming origin, development process, forecast and early warning, Philippines, China, typhoon impact, Philippines and Vietnam of the four deaths, the naming origin is to avoid confusion of typhoon names, 1 997165438+1October 25th-65438+February/kloc-. Among them, tropical cyclones in the northwest Pacific and South China Sea are named after Asian style. The naming method is as follows: make a naming table in advance, and then recycle it year after year. The naming table *** 140 is provided by 14 member countries and regions in the Asia-Pacific region to which WMO belongs. Among them, "sky map" is one of the names of 10 provided by Japan, which means sky map constellation. 1At 0: 201811point on October 3rd, a tropical disturbance occurred in the north-central Pacific Ocean southwest of Hawaii at about 0: 00, and the disturbance number given to it by the US Naval Research Laboratory was 98C. Since then, the tropical disturbance has been guided by the subtropical high ridge, moving westward and approaching the international international date line. 165438+1In the early morning of October 7th, the tropical disturbance crossed the international international date line from east to west and moved into the northwest Pacific. At 3 o'clock on the same day, the Japan Meteorological Agency identified it as a low-pressure area. At about 6 o'clock on the same day, the joint typhoon warning center rated the probability of turning it into a tropical cyclone within 24 hours as "low". At about1October 8 1 14, the joint typhoon warning center raised the probability of becoming a tropical cyclone within 24 hours to "medium". 165438+1At about 9: 30 on October 9, the Joint Typhoon Warning Center further upgraded its probability of becoming a tropical cyclone within 24 hours to "high", and at the same time issued a tropical cyclone formation warning (TCFA), which was later upgraded to a tropical depression by the Japan Meteorological Agency. 165438+1October 10 At 9: 30, the joint typhoon warning center reduced the probability of tropical cyclone formation within 24 hours to "medium" and cancelled the early warning of tropical cyclone formation. Later, the Japan Meteorological Agency confirmed that it had completely dissipated. At about 1 65438+1October/day 14, the joint typhoon warning center further reduced its probability of becoming a tropical cyclone within 24 hours to "low". 165438+1October 12 At 9: 00, the Japan Meteorological Agency once again recognized it as a low-pressure area. 165438+1October14th, around 2 1, Japan Meteorological Agency upgraded it to tropical depression again. 165438+1October 15 At 4 o'clock on the 5th, the joint typhoon warning center once again upgraded the probability of becoming a tropical cyclone within 24 hours to "medium". 165438+1October 17 at around 22: 30, the joint typhoon warning center once again raised its probability of becoming a tropical cyclone within 24 hours to "high" and issued a tropical cyclone generation warning (TCFA) simultaneously. At 3 o'clock on June165438+1October 18, the Japan Meteorological Agency issued a gale warning (GW). At about 15 that day, joint typhoon warning center upgraded it to a tropical depression and gave the official figure of 33W. 165438+1At 8 o'clock on October 20, the Hong Kong Observatory upgraded it to a tropical depression. At about 14, the Central Meteorological Observatory identified it as a tropical depression. 165438+1At around 20: 00 on October 22nd, the Joint Typhoon Warning Center took the lead in upgrading it to a tropical storm. At about 2 1 on that day, the Japan Meteorological Agency upgraded it to a tropical storm, giving it the international number 1829 and naming it Tiantu. At about 23 o'clock that day, the Central Meteorological Observatory upgraded it to a tropical storm. 165438+1At 8 o'clock on October 23, Japan Meteorological Agency upgraded it to a severe tropical storm, and later the Hong Kong Observatory upgraded it to a tropical storm. At about 20 o'clock that day, the Central Meteorological Observatory upgraded it to a strong tropical storm. 165438+1At 8: 00 on October 24, the joint typhoon warning center upgraded it to a first-class typhoon, which was later upgraded to a severe tropical storm by the Hong Kong Observatory. At about 14 that day, Japan Meteorological Agency upgraded it to a typhoon. At around 20 o'clock that day, the Japan Meteorological Agency downgraded it to a strong tropical storm. Typhoon Tiantu No.29+2065438+2008 165438+ Route Map1At 8: 00 on October 25th, it was successively downgraded to a tropical storm by the Typhoon Warning Center and the Hong Kong Observatory. At about 1 1, Japan Meteorological Agency downgraded it to a tropical storm. At noon that day, "Tiantu" landed on the southern coast of Vietnam. When landing, the maximum wind force near the center10 (25m/s), and the lowest air pressure in the center is 988 hectopascals. At about 17, the Central Meteorological Observatory downgraded it to a tropical storm. At about 20 o'clock that day, the joint typhoon warning center downgraded it to a tropical depression. At about 23 o'clock that day, the Central Meteorological Observatory and the Hong Kong Observatory successively downgraded it to a tropical depression, and jointly issued a final warning (FW) with the Typhoon Warning Center. 165438+1At 5 o'clock on October 26th, the Central Meteorological Observatory stopped numbering it. At 8 o'clock that day, the Japan Meteorological Agency downgraded it to a tropical depression, and later the Hong Kong Observatory downgraded it to a low-pressure area. 165438+1At 9: 00 on October 27th, the Japan Meteorological Agency judged that it had completely dissipated. Among the best paths released later, Japan Meteorological Agency confirmed that it intensified into a tropical storm at18: 00 on October 22nd 165438, but lowered the peak wind speed from 65kt to 60kt. The Central Meteorological Observatory increased the peak wind speed from 30m/s to 33m/s ... Forecast and Warning The Philippine Atmospheric Geophysics and Astronomy Administration issued the storm signal 1 1 at 5: 00 on October 20th/9th, and it was released on1October 22nd/kloc-.
