Solution (By JKSSB Mock Tests)
Wind backing is a counterclockwise change in wind direction with altitude in the Northern Hemisphere (e.g., from south to east). Backing typically indicates cold air advection.
Explanation:
The increase in temperature with altitude in the thermosphere is due to the absorption of solar radiation by the few gas molecules present.
