Which turbulence intensity corresponds to a rise or drop of 1 meter?

Which turbulence intensity corresponds to a rise or drop of 1 meter?

• A. Light.
• B. Moderate.
• C. Severe.
• D. None of the above.

Answer: (A)

Turbulence intensity describes how strong the vertical air motions feel to the aircraft. Light turbulence involves only slight, erratic changes in altitude and attitude. A rise or drop of about 1 meter is a small, easily noticeable shift in altitude, which fits this level. Moderate turbulence would produce more pronounced altitude changes, often several meters, and severe turbulence causes large, abrupt, potentially disruptive motions. So, a 1-meter change aligns with light turbulence because it’s a small, initial disturbance rather than a more noticeable or violent one.
