Choose the correct combination of the physical properties (A, B, C and D) that are TRUE for the Indian summer monsoon system. A – deep, B – moist, C – barotropic, D – baroclinic
Indian Summer Monsoon: True Physical Properties
The question asks to identify the physical properties that accurately describe the Indian summer monsoon system. Let's analyze each property:
- A - Deep: The monsoon system involves a significant vertical extent in the atmosphere, often extending several kilometers high, facilitating large-scale moisture transport and cloud formation. Thus, it is considered deep.
- B - Moist: Moisture supply, primarily from the Indian Ocean, is a defining characteristic of the monsoon, leading to heavy precipitation. Hence, it is moist.
- C - Barotropic: A barotropic atmosphere lacks horizontal temperature gradients, meaning pressure surfaces and temperature surfaces do not intersect. The monsoon is driven by differential heating (land vs. sea, equator vs. poles), creating significant horizontal temperature gradients. Therefore, the atmosphere is not barotropic.
- D - Baroclinic: The presence of horizontal temperature gradients is known as baroclinicity. As the monsoon is driven by temperature differences, it exhibits baroclinic characteristics, which are essential for its development and dynamics.
Correct Combination Identification
Based on the analysis:
- Property A (Deep) is TRUE.
- Property B (Moist) is TRUE.
- Property C (Barotropic) is FALSE.
- Property D (Baroclinic) is TRUE.
The true properties are A, B, and D.
Therefore, the correct combination is A, B, D.
