Typhoon Betty, international code 198708, international name BETTY, 1987 Northwest Pacific typhoon. Formed: 1987-08-07 00:00:00, ended: 1987-08-17 06:00:00. Peak intensity: Super Typhoon, minimum central pressure: 890 hPa, max wind: 71m/s.
Typhoon Betty at 1987-08-07 00:00:00 at 8.4°N, 134.2°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Super Typhoon intensity with max winds of 71 m/s (~256 km/h) and a minimum central pressure of 890hPa, recorded at 1987-08-11 12:00:00.
1987-08-17 06:00:00 After, Typhoon Betty gradually weakened and was numbered off on 1987-08-17 06:00:00 was numbered off; its lifecycle recorded 42 track points.
Typhoon Betty (198708)'s life begins at the Northwest Pacific ocean surface, the overall path shows a stable WN go toward, with no apparent turn toward or reflux phenomenon. From the formed early Nameless phase (August 7, 134.2°E) to the dispersal end (August 17, 100.2°E) , its length range exceeds 34 degrees, the latitude rises from 8.4°N slowly to 19.8°N. In the Moving speed, early August 7 to 9th, the system Moving is relatively slow, the daily duration varies about 1-2 degrees; Go to the intensified period (August 10, 10 to 13) , Moving speed significantly accelerates, especially during November 13th, while the systemins Super Typhoon Intensity, fast toward to
Betty's Intensity evolution has the typical characteristics of 'fast enhancement, long maintenance, slow weakening'. system at August 9 upgraded to Tropical Storm, then rapidly developed within 24h by Severe Tropical Storm to Severe Typhoon (August 10, 18, 48m/s) . August 11 at 12, Max Wind near the center reached 71m/s, established as Super Typhoon level. It is noteworthy that the Intensity peakined Time extremely long, from August 11 to August 15, the system remained at Super Typhoon level (wind speed≥51m/s) for up to 4 days Time, even though on August 14 there was a second reinforcement of wind speed back to 59m/s. Until August 16, environmental factors affected, intensity dropped dramatically, by Typhoon speed dropped directly into the
Compared to 1984 Betty (top only for Severe Tropical Storm) and 1975 Betty (top for Severe Typhoon), 1987 system Intensity is significantly higher.
