Which one among the following is the most plausible explanation for the location of the Thar Desert in Western India ?

Result
Your answer: —  Â·  Correct: D
Explanation

The location of the Thar Desert in Western India is primarily attributed to the unique atmospheric conditions during the monsoon season. While the Aravalli Range lies parallel to the South-West Monsoon winds, failing to provide an orographic barrier, the most plausible explanation involves the upper air circulation. The moisture-laden South-West Monsoon winds entering the region are prevented from rising and condensing due to the presence of a dry, warm upper air current. This atmospheric stability, often characterized by temperature inversions or descending air from subtropical high-pressure cells, inhibits the vertical ascent necessary for cloud formation and precipitation. Consequently, despite the presence of moisture in the lower atmosphere, the lack of condensation leads to extreme aridity. Other factors include the rain-shadow effect and high evaporation rates due to intense summer heat.
