Typhoon Polly (197802) 的生命史始 at Northwest Pacific洋面, 整体路径呈现典型的“先W后N再NE”的抛物线型转 toward 特征. formed初期 (6月13日至14日) , 系统位 at lat 20°至23°N, 134°至138°之间, 主要 toward NW. 值得注意的是, 在6月15日00:00至12:00期间, Typhoon 中心The latitude从24.1°N微降至23.3°N, During继续W移, 显示出短暂的停滞或SW toward 调整迹象, 随后 at 6月16日开始重新转为NNW.
When the system Moving to lat 26.5°N, 126.1° near, its Moving direction gradually shifted from NW to positive N, and then toward NE direction accelerated. on June 20, with the latitude rapidly rising to 33.4°N, the length rebounded to 130.4°E, indicating that the system has fully Go to W wind belt guided airflow control zone, completed the turn toward and accelerated away from continental coastal .
From the perspective of intensity changes, Typhoon Polly experienced a slow improvement after rapid weakening of the entire process. The initial phase is Nameless, max windins fluctuations between 7-12m/s. On June 17, with toward NMoving, intensity began to increase steadily, wind speed from 15m/s increased to 17m/s. On June 19, 00:00, the system upgraded to Tropical Storm (20m/s) , and at the same day at 12:00 reached peak intensity, sex set to Severe Tropical Storm, max wind recorded 25m/s. However, the peak stateins Time extremely short, Go to High latitude ocean after, influenced by environmental factors, intensity rapidly decreased.
Polly (199513) and Polly (197415) both reached the Severe Typhoon level, and Polly (196807) reached the Severe Tropical Storm level in 1968.
