Typhoon Olga (199906) 的生命史始 at Northwest Pacific低The latitude海域, 整体路径呈现典型的“NW—N—NE”转 toward 型特征. formed初期 (7月26日至28日) , 系统在5.5°N至11.7°N之间稳定 toward NW, During从138.7°EW退至135.2°E, 显示其受低层信风引导显著. 7月29日后, 随着纬度升高, 路径逐渐 toward N分量增加, Moving direction由纯NW转为N.
When the system Moving to 23.7°N, near 130°E, the path curvature changes significantly, followed by Go to accelerate N in the first phase. After August 2, the Typhoon center crossed 30°N, the path further toward E, eventually rapidly toward NE, until 41.8°N high latitude waters dispersed between August 3 and August 4.
Olga的Intensity演变经历了完整的“ formed—增强—维持—减弱”过程. 初始阶段为Nameless, wind speed维持在10m/s. 7月29日起开始显著加强, at 7月30日06:00升级为Tropical Storm, 同日18:00迅速增强为Severe Tropical Storm. 7月31日18:00, 系统在23.7°N附近达到Typhoon intensity with max winds of 35m/s.
Peak intensity appeared between August 1 and August 2, max wind stable between 38m/s and 41m/s (data record peak is 41m/s), andined at the intensity level of about 48h.
Compared with the same name History, Olga's peak intensity (Typhoon level, 41m/s) in 1999 was weak at 1972 Olga (Super Typhoon) and 1970 Olga (Super Typhoon) and at the same degree as Olga (Typhoon) in 1961.
