1979 Typhoon Past typhoons named Roger Typhoon archive

[Quick Archive Overview]Typhoon Roger (No.197918, a historical number used before 1981) was a 1979 Northwest Pacific typhoon. It peaked as a severe typhoon, with maximum winds of 50 m/s and a minimum central pressure of 932 hPa. It did not make landfall in China, was decommissioned on 1979-10-15, and had 59 recorded track points throughout its lifetime.

Numbering system: International cyclone numbering in the Northwest Pacific has been assigned by the JMA in Japan, the Tokyo Regional Specialized Meteorological Center, since 1981. This system did not exist in 1979, and 197918 is the historical identifier continued by the CMA. The numbers assigned that year by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological agencies may differ and cannot be directly compared.
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

Track and Movement Characteristics

Typhoon Roger (197918) 的生命史始 at 1979年10月1日02:00, formed at Philippines以E海域 (14°N, 118°E) , 初始状态为Tropical Depression. 在 formed初期, 系统呈现出不稳定的徘徊特征, 先 toward NW direction短暂Moving至16.6°N附近, 随后受引导气流影响, at 10月4日至5日期间出现明显的S折回调, 纬度从14.5°N回落至14°N, 经度亦 toward W微调. 自10月6日起, Typhoon 确立稳定的W行路径, 整体Moving direction维持W, 期间伴随轻微的SN摆动. 整个生命周期中, 该系统始终保持在低纬度海域活动, 最N端未超过16.6°N, 最S端触及11.2°N. 直至10月15日14:00在S海W部海域 (12.5°N, 109.5°E) 消散, 全程无Landfall记录, 主要活动区域集中 at 11°至17°N, 109°至121°之间的广阔洋面.

Intensity evolution and historical comparison

Roger的Intensity演变经历了典型的“缓慢增强-快速爆发-逐渐减弱”过程. formed初期Intensity维持在Tropical Depression级别 (10-15m/s) . 10月6日 intensified into Tropical Storm后, Go to 快速增强期, 仅用3天Time便由Tropical Storm (20m/s) 跃升为Severe Typhoon. 10月10日至11日达到巅峰状态, 中心最低气压降至932hPa, max wind 达50m/s, 定性为Severe Typhoon. 巅峰维持Time较短, 10月12日起开始减弱, wind speed降至40m/s以下, 并最终 at 消散前降级为Tropical Depression.

Compared with previous storms of the same name, Typhoon Roger in 1979 was significantly more intense. Its peak central pressure of 932 hPa was much lower than that of Roger in 1986 (955 hPa), Roger in 1989 (975 hPa), and Roger in 1982 (980 hPa). In terms of maximum wind speed, Roger in 1979 reached severe typhoon intensity with winds of 50 m/s, while the other storms of the same name peaked at either severe tropical storm or severe typhoon strength, as in 1986. This made the 1979 Roger the most energetic and tightly organized system among the listed storms of the same name.
