Match the climatic phenomena and atmospheric features of India in List I with their correct meteorological mechanisms or characteristics in List II.
- Tropical Easterly Jet Stream (TEJ)Establishes over the southern Indian Peninsula in summer and helps steer tropical depressions into the subcontinent
- Subtropical Westerly Jet Stream (STWJ)Withdraws from north of the Indo-Gangetic plain to the north of the Himalayas prior to the onset of the southwest monsoon
- Inter-Tropical Convergence Zone (ITCZ)Shifts northward over the Indo-Gangetic Plain in summer to form a prominent low-pressure monsoon trough
- Southern OscillationRepresents the interannual sea-level pressure seesaw between the tropical southern Pacific and Indian Oceans
Cevap
The Tropical Easterly Jet Stream matches with establishing over the southern Indian Peninsula in summer and steering tropical depressions; the Subtropical Westerly Jet Stream matches with withdrawing north of the Himalayas before monsoon onset; the Inter-Tropical Convergence Zone matches with shifting over the Indo-Gangetic Plain to form the monsoon trough; and the Southern Oscillation matches with the pressure seesaw between the Pacific and Indian Oceans.
Each atmospheric component is correctly paired with its driving mechanism in the monsoon system: the Tropical Easterly Jet Stream steers summer rain depressions; the Subtropical Westerly Jet Stream retreats north of the Himalayas prior to onset; the ITCZ shifts northward over the Gangetic Plain as the monsoon trough; and the Southern Oscillation reflects interannual ocean-atmosphere pressure variations.
