Question

The jet aircrafts fly very easily and smoothly in the lower stratosphere. What could be the appropriate explanation?
1. There are no clouds or water vapour in the lower stratosphere.
2. There are no vertical winds in the lower stratosphere.
Which of the statements given above is/are correct?

Accepted Answer

The correct answer is C because both statements accurately describe the conditions in the lower stratosphere that favor jet flight.

Regarding statement 1, the stratosphere is very dry and contains almost no water vapor or clouds. This ensures high visibility and prevents weather related disturbances like storms or heavy rain which are common in the troposphere.

Regarding statement 2, unlike the troposphere where air moves up and down due to convection, the stratosphere is characterized by horizontal air flow. The absence of strong vertical winds or convection currents provides a stable environment, which prevents turbulence and allows aircraft to fly smoothly.
