Typhoon Polly trajectory analysis
Track and Movement Characteristics
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 中心纬度从24.1°N微降至23.3°N, 经度继续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. 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 the continental coastal .
Intensity evolution and historical comparison
From the perspective of intensity changes, Typhoon Polly has experienced a slow increase after a rapid decline of the whole process. The initial stage is Tropical Depression, max windins fluctuations between 7-12m/s. On June 17, with toward NMoving, intensity begins to increase steadily, wind speed from 15m/s increases to 17m/s. On June 19, 00:00, the system upgrades to Tropical Storm (20m/s) , and at the same day at 12:00 reaches peak intensity, set to Severe Tropical Storm, max wind records 25m/s. However, the peak stateins Time extremely short, Go to High latitude, after environmental factors, intensity rapidly decreases.
Polly (199513) and Polly (197415) both reached the Severe Typhoon level, and Polly (196807) reached the Severe Tropical Storm level in 1968.
