Root Cause

The pressure difference between inside and outside a building during a tornado is too small to cause explosion; opening windows actually allows wind and debris to enter, increasing damage and injury risk.

龙卷风期间建筑物内外的压力差太小，不足以引起爆炸；打开窗户实际上会让风和碎片进入，增加损坏和受伤风险。

Workarounds

  1. 90% success Close all windows and doors, then move to a basement, storm cellar, or an interior room on the lowest floor (e.g., bathroom) away from windows.

  2. 85% success If in a mobile home, evacuate immediately to a designated shelter or a sturdy building; mobile homes are unsafe even with windows closed.

中文步骤

  1. 关闭所有门窗，然后移动到地下室、风暴地窖或最低层的内部房间（例如浴室），远离窗户。
  2. 如果在移动房屋内，立即撤离到指定的避难所或坚固的建筑物；即使关窗，移动房屋也不安全。

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Tornado winds are rotating and can enter from any direction; this creates a wind tunnel effect that can tear the roof off.

  2. 80% fail

    This creates internal pressure and allows debris to fly inside, significantly increasing injury risk.
