Conning occurs in neutral atmosphere, when wind velocity is greater than

  1. 32 km per hour

  2. 42 km per hour

  3. 52 km per hour

  4. 72 km per hour

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coning is a type of plume behavior in air pollution meteorology. It typically occurs under neutral stability conditions when wind speeds are moderate to high, often cited as greater than 32 km/h.
