Typhoon Dinah Route Characteristics
Track and Movement Characteristics
Typhoon Dinah (197406) 的生命史始 at Northwest Pacific洋面, 整体呈现稳定的WNWMovingTrend. formed初期 (6月7日) , 系统位 at 12°N, 135.6°E附近, 随后迅速 toward W穿越Philippines群岛以E海域. 从坐标序列分析, 该Typhoon 在6月7日至6月10日期间, 纬度由12°N缓慢N抬至15.4°N, 经度则从135.6°E快速W移至122.3°E, 显示出较强的W风引导气流作用.
During June 11 00:00 to 12:00, the Typhoon center latitude remains unchanged at 16.5°N, while the length continues to W shift, indicating that at this time the system is dominated by the sub-tropical high-pressure S side of the E air flow, showing a correct W Moving path. After June 12th, as the latitude again N rises to 21°N, the path gradually turns toward NW direction, finally at June 14th 18:00 at 103°E near the weakened dispersion.
Intensity evolution and historical comparison
Dinah的Intensity变化经历了“快速增强—波动维持—逐渐减弱”三个阶段. 6月7日为Tropical Depression (15m/s) , 仅用不到两天Time, at 6月9日12:00 intensified into Typhoon (33m/s) , 并 at 6月10日00:00达到peak intensity, max wind 35m/s. 值得注意的是, 其在6月10日12:00曾短暂 weakened into Severe Tropical Storm (25m/s) , 但随后在6月11日12:00至6月12日12:00期间重新加强并维持在Typhoon 级别 (33-35m/s) , 显示出在S海海域具备二次增强的能力. 6月13日起, 系统开始持续减弱, 最终降格为Tropical Depression.
与历届同名Typhoon 相比, 1974年Dinah的Intensity显著偏弱. 数据显示, 1987年, 1980年及1967年的Dinah均达到“Super Typhoon”级别, 1977年Dinah亦为“Typhoon ”级. 相比之下, 1974年Dinah巅峰仅为CommonTyphoon 等级 (35m/s) , 且生命史较短 (约7.75天) , track points仅32个, 属 at 中等偏弱的Tropical Cyclone 过程.
