If a question discusses keeping aircraft routes above storm clouds, which reasoning is most appropriate?
Answer and explanation
Correct answer: Weather disturbances are relatively fewer in the lower stratosphere
The governing concept is the vertical structure of the atmosphere. Most clouds and almost all important weather occur in the troposphere, where convection and turbulence are active. The lower stratosphere is comparatively stable, so aircraft may prefer suitable routes near or within it when conditions and aircraft performance allow. Option A is correct; B is false because the exosphere has virtually no clouds, C is false because pressure decreases with height, and D is false because clouds commonly form in the troposphere.
