根因分析

离岸流是狭窄、快速流动的通道，垂直于海岸流动；如果游泳者位于离岸流中心，平行游泳可能使其保持在离岸流中，而逃生方向取决于离岸流的确切位置和形状。

English

Rip currents are narrow, fast-moving channels that flow perpendicular to the shore; swimming parallel may keep the swimmer in the current if they are in the center, and the direction of escape depends on the current's exact location and shape.

解决方案

  1. 如果被离岸流困住，漂浮或踩水以节省体力。不要惊慌。挥舞手臂求救。
  2. 沿着与海岸平行的方向游泳，方向与沿岸流（波浪破碎的方向）一致，不要直接对抗离岸流。一旦离开离岸流，以斜角游回岸边。
  3. 如果无法游出离岸流，仰面漂浮，让离岸流带你直到它减弱，然后游回岸边或求救。

无效尝试

常见但无效的做法:

  1. Swimming parallel to the shore in the direction of the current flow 80% 失败

    If the swimmer is in the center of the rip current, swimming parallel may not exit the current; the current can be 10-50 meters wide, and the swimmer may tire before exiting

  2. Swimming parallel in the opposite direction of the current flow 70% 失败

    This can push the swimmer into the current's strongest part and cause exhaustion; the direction of the rip current is not always obvious

  3. Trying to swim directly back to shore against the current 95% 失败

    This is the most common fatal mistake; the rip current is stronger than the swimmer, and exhaustion leads to drowning
