Tropical Easterly Jet Characteristics
The Tropical Easterly Jet (TEJ) is a significant atmospheric phenomenon impacting India, particularly during the monsoon season. Understanding its key features is crucial.
- Altitude: The TEJ is a high-altitude jet stream, typically observed at pressure levels around 100 hPa.
- Period: It is strongest and most prominent during the summer monsoon season, which spans from June to September.
- Latitude: The jet is generally found over lower latitudes, specifically observed around $10^\circ\text{N} - 15^\circ\text{N}$ during its peak activity over the region.
Analyzing Jet Stream Options
Let's evaluate the given options based on the known characteristics of the Tropical Easterly Jet over India:
- Options 1 and 3 are incorrect because they specify the period as October to November. This is the post-monsoon or retreating monsoon season, during which the TEJ is either absent or significantly weaker and shifts southward.
- Option 2 suggests 200 hPa. While 200 hPa is a typical altitude for jet streams (like the Subtropical Westerly Jet), the Tropical Easterly Jet is characteristically found at higher altitudes, closer to 100 hPa.
- Option 4 correctly identifies the high altitude (100 hPa), the primary monsoon period (June to September), and the typical low latitude ($10 - 15^\circ\text{N}$) where the Tropical Easterly Jet is observed over India.
Therefore, the Tropical Easterly Jet over India is observed at the 100 hPa level during the June to September period over $10 - 15^\circ\text{N}$ latitudes.
