Typhoon Irving, international code 197909, international name IRVING, 1979 Northwest Pacific typhoon. Formed: 1979-08-07 12:00:00, ended: 1979-08-18 06:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 955 hPa, max wind: 46m/s.
Typhoon Irving at 1979-08-07 12:00:00 at 14°N, 137.7°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 46 m/s (~166 km/h) and a minimum central pressure of 955hPa, recorded at 1979-08-15 00:00:00.
1979-08-18 06:00:00 After, Typhoon Irving gradually weakened and was numbered off on 1979-08-18 06:00:00 was numbered off; its lifecycle recorded 44 track points.
Typhoon Irving (197909) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“抛物线”型Moving特征. formed初期 (8月7日至10日) , 系统在14°N至18°NThe latitude带内主要 toward WN, During从137.7°E逐渐W移至131.1°E, 期间纬度变化相对平缓, 显示出受副热带高压S侧引导气流影响的稳定W行Trend. 8月11日前后, 系统出现明显的路径转折, Moving direction由W toward 转为NW toward , 随后加速 toward N推进.
The key turn toward point appeared between August 15 and 16. At this time the Typhoon center position at 25.9°N to 31.7°N, 124°E to 123.7°E near, the length almost stagnated, marking the system began to be affected by the pre-W wind belt airflow, the path from NW toward completely turned to NE toward.
In terms of intensity evolution, Irving underwent a complete 'formed-enhanced-top-weakened' process. Initial phase was Nameless, wind speedined at 10-17m/s. From August 12, the system Go to rapid enhancement period, developed rapidly by Severe Tropical Storm to Typhoon. on August 15, 00:00, Typhoon reached peak intensity, max wind recorded 46m/s, qualified as Severe Typhoon, andined the high intensity state for the following 18h. after August 16, with the latitude rise and Go to higher sea temperature ladder zone, intensity began to decline significantly, from Severe Typhoon descended to Severe Tropical Storm, finally weakened into Nameless and disappeared on August 18.
It peaked at Severe Typhoon level (46m/s), high at 1995 Irving (Severe Tropical Storm), 1992 Irving (Typhoon) and 1985 Irving (Severe Tropical Storm) only at the same intensity level as Irving (Severe Typhoon) in 1982.
