Typhoon Agnes trajectory
Characteristics of path
Agnes formed on August 25, 1981, with its initial center at 16°N, 148°E. Its track was generally NWward: from August 26 to 31, the center moved steadily from 16.7°N, 143°E to 28.2°N, 124.3°E, with latitude increasing and longitude decreasing as it gradually turned from westward to southwestward. After reaching 130.3°E on August 29, it turned further toward the SW. From August 30 to 31, longitude decreased from 126.7°E to 124.3°E, marking a notably curved portion of the track.
On August 31, the central pressure reached its minimum of 949 hPa and the maximum wind speed was 45 m/s, reaching Severe Typhoon intensity, after which the track began to turn toward . On September 1, the center was at 30.7°N, 123.2°E, the closest it came to 124°E throughout its journey. On September 2, it turned toward N, with longitude increasing to 123.8°E, before accelerating markedly toward the NE. From September 3 to 4, it moved from 34.1°N, 127.3°E to 42°N, 141.5°E. From September 4 to 6, it moved from 42°N, 141.5°E to 52.3°N, 167°E, eventually extending to 53°N, 174°E and following a high-latitude NE track. No landfall was recorded.
Evolution of intensity
Agnes began as a tropical depression, strengthened into a tropical storm on August 27, reached severe tropical storm intensity on August 28, and became a typhoon on August 29. On August 30, the maximum wind speed rose to 40 m/s and the pressure fell to 960 hPa. On August 31, it reached its peak intensity, with maximum winds of 45 m/s and a minimum pressure of 949 hPa. Its intensity then declined: on September 1, maximum winds fell to 40 m/s, and on September 2 it weakened to a severe tropical storm, with maximum winds of 30 m/s and a pressure of 980 hPa.
On September 3, pressure rose to 986 hPa and maximum winds fell to 25 m/s. On September 4, pressure returned to 980 hPa, after which it maintained severe tropical storm intensity through the end of its lifetime, with maximum winds of 25 m/s. Overall, it followed a pattern of continuous strengthening, peaking on August 31, marked weakening, and then maintaining severe tropical storm intensity while turning toward the NE.
Historical Comparison
Among storms with the same name, Agnes (198806) peaked at severe tropical storm intensity in 1988, with a minimum pressure of 980 hPa, while Agnes (198418) reached severe typhoon intensity in 1984, with a minimum pressure of 925 hPa. By comparison, Agnes in 1981 had a minimum pressure of 949 hPa and maximum winds of 45 m/s. Its peak intensity exceeded that of the same-named typhoon in 1988, but its minimum pressure was higher than that of the same-named typhoon in 1984, indicating that its most intense phase fell between the two.
