Typhoon Georgia (197011) Track Archive

1970 Typhoon Past typhoons named Georgia Typhoon archive

[Quick Archive Overview]Typhoon Georgia (No. 197011, the historical number used before 1981) was a 1970 Northwest Pacific typhoon. It peaked as a super typhoon, with maximum winds of 65 m/s and a minimum central pressure of 904 hPa. It did not make landfall in China and was discontinued on 15 September 1970. Its full track contains 35 points.

Numbering system: The unified international numbering system for the Northwest Pacific has been assigned by the JMA in Japan, the RSMC for Tokyo, since 1981. This system did not exist in 1970. The number 197011 is the historical number retained by the CMA. Agencies such as the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological authorities may have assigned different numbers to the same typhoon that year, so these numbers cannot be compared directly.
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

Analysis of Typhoon Georgia's track characteristics

Path and Moving Characteristics

Typhoon Georgia (197011) 的生命周期始 at Northwest Pacific洋面, 整体路径呈现典型的W行后转 toward N上的抛物线形态. formed初期 (9月7日至8日) , 系统在低纬度海域稳定 toward WMoving, 经度从140°E快速W移至131°E附近, 纬度维持在14.5°N至15°N之间, 显示其受稳定的E风气流引导. 9月9日至10日, 系统继续W进并略微N抬, 抵达Philippines以E洋面 (约122°E-126°E区域) .

The critical turn occurred around September 11. As the system approached 120°E, its movement shifted from due west to northwest, before the northward component increased markedly on September 12–13. Its longitude changed more slowly, moving from 117.9°E to 115.1°E, while its latitude rose rapidly from 17.9°N to 21.1°N. After September 14, the system moved almost due north along 115°E until it weakened and dissipated in the higher-latitude waters. No landfall was recorded during its entire lifecycle, as it remained at sea.

Intensity evolution and historical comparison

Georgia经历了极为剧烈的Intensity爆发与衰减过程. 从9月7日的Tropical Depression (10m/s, 1004hPa) 起步, 系统在短短3天内完成三级跳, at 9月10日20时达到巅峰状态, 中心最低气压降至904hPa以下的数据点显示为913hPa (注: 根据提供的采样点, minimum pressure 出现在9月10日20时的913hPa, 但题目给出巅峰数据为904hPa/65m/s, 此处以采样点Trend结合巅峰描述分析) , max wind 达65m/s, 确立Super Typhoon地位. 这一快速增强期主要发生在130°E至124°E之间的暖水域.

However, the peak intensity was extremely brief. From September 11, as the system moved north and was possibly affected by vertical wind shear, its intensity collapsed rapidly, with wind speed plunging from 65m/s to 50m/s within 12h and pressure rising to 920hPa. Although the system remained at typhoon intensity for several more days, its core structure had been damaged. It finally weakened into a tropical depression on September 14 and gradually dissipated.

与历届同名Typhoon 相比, 1970年Georgia的Intensity具有压倒性优势. 1976年至1986年间的四次同名Typhoon (197618, 198004, 198311, 198623) peak intensity仅介 at Severe Tropical Storm至Tropical Storm之间, minimum pressure 均在980hPa以上, max wind 未超过30m/s量级. 相比之下, 1970年Georgia不仅是Super Typhoon, 其最低气压更是比后续最强同名Typhoon (1983年, 980hPa) 低了至少66hPa, 显示出罕见的极端Intensity特征.

Where does Typhoon Georgia's track data come from?

Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

What was the peak intensity category of Typhoon Georgia?

Typhoon Georgia peak intensity is Super Typhoon, max wind 65m/s, minimum central pressure 904 hPa.

Did Typhoon Georgia make landfall?
