The SummaryTyphoon Matsa (international code 200509) is a 2005 Northwest Pacific typhoon; peak intensity Severe Typhoon, max wind 45m/s, minimum central pressure 950hPa, not in China Landfall, 2005-08-09 was numbered off, recording 101 track points.
Typhoon Matsa, international code 200509, international name MATSA, 2005 Northwest Pacific typhoon. Formed: 2005-07-31 20:00:00, ended: 2005-08-09 05:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 950 hPa, max wind: 45m/s.
Typhoon Matsa at 2005-07-31 20:00:00 at 11.7°N, 134°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Severe Typhoon intensity with max winds of 45 m/s (~162 km/h) and a minimum central pressure of 950hPa, recorded at 2005-08-04 18:00:00.
2005-08-09 05:00:00 After, Typhoon Matsa gradually weakened and was numbered off on 2005-08-09 05:00:00 was numbered off; its lifecycle recorded 101 track points.
Typhoon Matsa (200509) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的“NW行—N抬—NE折”的抛物线形态. formed初期 (7月31日) , 系统位 at 11.7°N, 134°E附近, 以Tropical StormIntensity toward NW direction稳定Moving. Go to 8月上旬, 随着The latitude升高, 其Moving路径逐渐由NW转为N. 观测数据显示, 从8月4日至8月5日, Typhoon 中心在22°N至25°N区间内维持较为密集的经 toward Moving, 表明此时引导气流发生显著变化.
It is worth noting that after the Typhoon arrived at 29.5°N, near 120.2°E around 17:00 on August 6, the path showed a marked toward E increased trend, then rapidly turned toward NE, eventually at August 9 at 38.2°N, near 120.3°E. Thro the process, the Typhoon did not record Landfall behavior, always in marine activity, and its path turning point was mainly concentrated at between 25 degrees and 30 degrees, in line with the typical motion laws of the sub-tropical high-pressure edge Typhoon.
Matsa's Intensity evolution underwent rapid enhancement, peak maintenance and rapid weakening in three stages.The initial phase was Tropical Storm (18m/s, 998hPa) , then rapidly strengthened within 48h. by August 3, 17:00, Pressure dropped to 960hPa, wind speed to 40m/s, upgraded to Typhoon level.
At the peak, Matsained about 30h high Intensity characteristics (August 5 01:00 to August 6 01:00), while the air pressure was stable at 950hPa, wind speed remained at 45m/s. However, once overlat 29 degrees Go to higher latitude waters, its Intensity sharply decreased. From August 6 17:00, within a short 12h, Pressure returned to 980hPa, wind speed gradually dropped to 30m/s, declined to Severe Tropical Storm. Since then, with N further up to 30°NN, affected by cold sea water and vertical wind shifts, the system continued to weaken, eventually ended in the temperate zone with Tropical StormIntensity life history.
