The strongest tropical cyclone recorded on earth is the typhoon Tip in June/KOOC-0/979+/KOOC-0/0/2, with a magnitude of/KOOC-0/7.
Review of Taipei 7920
Disturbance development period
1979 and 10, the monsoon trough is very active and has a very wide range. There are three disturbances from the South China Sea to the northwest Pacific Ocean at east longitude180, and then they all develop into tropical cyclones. From the west, the disturbance of Sarah, Roger, Tip and Roger is at 10-20 degrees north latitude, which is the northernmost of the three disturbances, and the southernmost is Tip's disturbance. Tip's disturbance was initially influenced by Roger's disturbance, and its development was extremely unstable and its path was irregular. On June 4th 10, joint typhoon warning center issued a tropical cyclone warning (TCFA) to alert the disturbance. Roger has intensified into a tropical storm; 10 year1On the afternoon of October 4th, Japan decided that the disturbance of Tip was tropical depression.
Cyclone development period
The newly formed tropical depression was affected by the huge tropical storm Roger from 4th to 8th, with extremely irregular path, high intensity and slow speed. Roger turned into an extratropical cyclone with the intensity of tropical storm on the 7th, and the tropical depression broke away from Roger's suppression and intensified into a tropical storm, but it was named Tip, TAIPEI.
The appearance of Taipei is of great concern to joint typhoon warning center, because its path may sweep Guam, the headquarters of the Joint Typhoon Police Center. Taipei moved northwest and intensified into a severe tropical storm on the evening of the 8th. As a result, Taipei passed about 45km south of joint typhoon warning center on the evening of 9th with the intensity of strong tropical storm. Soon after, Taipei became a large-scale subtropical high typhoon, which made the amplitude of Taipei very strong.
The legendary typhoon, the appearance of 870 hectopascals
After Taipei became a typhoon, the strengthening did not stop, but increased rapidly; Records in Japan show that the air pressure drops almost every time, from 965 hectopascals to 920 hectopascals a day, which is the record of10-1. Due to the sudden change of environment, Taipei became a strong typhoon at 10, with extremely wide diameter and perfect overall organization. 1 1 On that day, the central wind force was maintained at about 90 knots in the morning, and the enhancement was more obvious below. The central wind force dropped to 130 knots, and the air pressure was maintained at 900 hectopascals.
The legendary typhoon was born in 12. Since 00: 00, the central air pressure has been below 900 hectopascals, and it has dropped rapidly. At 08: 00 Beijing time, it has dropped to 875 hectopascals; . The central wind power 120 kts is slightly lower than yesterday, but the overall organization is still strengthening, and the system scope is already large, but it is still expanding. In the afternoon, at 1400 Beijing time, Teppeda reached its peak, with a central air pressure of 870 hectopascals, sustained wind 140 knots and gust165 HTS; . In addition to the central wind being questioned, Taipei set a record for the lowest pressure and the largest tropical cyclone in history. 12, Taipei strong wind circle (33 knots) is 2220 kilometers wide, and storm circle (92 knots) is 560 kilometers wide; Wide. Taipei also has a very strong warm heart structure.
At that time, some fans in Hong Kong said that the Royal Hong Kong Observatory (the name before the reunification, that is, today's Hong Kong Observatory) had issued a warning to the media about Taipei, which is more than 0/000 kilometers away from Hong Kong/Kloc. This move is very rare.
The slow moving speed of Taipei is also one of the reasons for its rapid enhancement.
Weakened special match
The air pressure in Taipei has been kept below 900 hectopascals until 13, and the moving speed is still slow, resulting in a slow weakening speed, and the central wind force is generally maintained at around 125 knots. In the afternoon, the central wind dropped to 1 10 knots. Although its scope began to shrink, it is still a huge platform. On June 5438+04, the wind weakened and the central wind pressure rose rapidly, and Taipei began to turn. On 16, the wind power in Taipei center dropped to 95 knots and maintained at 17. The system moved to the east of Taiwan Province Province, but it was still a giant station.
The decline of Taipei
/kloc-On the morning of 0/8, Taipei crossed the Tropic of Cancer, left the tropical ocean and turned northeast with strong typhoon intensity. /kloc-swept Japan with a wind speed of 70 kts on 0/9 and turned into an extratropical cyclone. Its extratropical cyclone also swept the Aleutian Islands and will enter the central Pacific Ocean in the next two days.
