Typhoon Dinah Route Review
Typhoon Dinah at 1971-05-25 06:00:00 at 12.1°N, 129.2°E over the Northwest Pacific; initial intensity: Severe Tropical Storm.
It peaked at Severe Typhoon intensity with max winds of 46 m/s (~166 km/h) and a minimum central pressure of -hPa, recorded at 1971-05-25 18:00:00.
1971-05-30 06:00:00 After, Typhoon Dinah gradually weakened and was numbered off on 1971-05-30 06:00:00 was numbered off; its lifecycle recorded 21 track points.
Typhoon Dinah Route Characteristics
Track and Movement Characteristics
Typhoon Dinah (197106)'s life began at the Northwest Pacific Ocean, presenting a stable NW toward MovingTrend. From the formed early 12.1°N, 129.2°E to the 21.9°N, 108.5°E before disintegration, its latitude continued to rise N, length significant W shift, no apparent path turn or stagnation. During May 25 to 26, the system at a faster speed toward WN direction crossed the Philippine to E ocean area, then Go to S SeaN. Thro the process, the Typhoon center remained always above the ocean, according to observations showing no Landfall behavior. This long About offshore Moving path allowed the system to maintain a relatively complete structure, until close to the Middle Scoastal peninsula.
Intensity Evolution Analysis
In the short 12h after formed, max wind rapidly increased from 28m/s to 35m/s, and at May 25 at 18:00 reached peak intensity, at this time for Severe Typhoon intensity with max winds of recorded 46m/s (Typhoon). It is worth noting that after reaching the peak, the system did not immediately significantly weaken, but in the subsequent 48h experienced a significant Intensity fluctuation: wind speed first dropped to 28m/s (Severe Tropical Storm), but at May 27 at 12:00 rebounded back to 41m/s (Typhoon ). This second reinforcement phenomenon suggests that the environment may have a short-term power support.
Comparison of Typhoon
In 1971, Dinah's peak intensity is Severe Typhoon (46m/s), while in 1980 Dinah (198022) and 1987 Dinah (198711) reached the Super Typhoon level, in which the minimum air pressure in 1987 was lower than 915hPa, showing extremely strong destruction potential.In comparison, Dinah's peak intensity in 1974 (197406) and Dinah's peak intensity in 1977 was only Typhoon level (responding to air pressure 965hPa).
