    Question

    In which of the following months does an easterly jet stream flow over the southern part of the Peninsula, reaching a maximum speed of approximately 90 km per hour?

    A.

    February

    B.

    June

    C.

    April

    D.

    December

    Correct option is B

    The Correct Answer is: (b) June
    Explanation:
     During the summer monsoon season a tropical easterly jet stream forms over the southern part of the Indian Peninsula.
     This Easterly Jet Stream, also known as the Tropical Easterly Jet (TEJ), is a high-altitude wind system that reaches speeds of up to 90 km/h or more.
     It typically develops due to the intense heating of the Tibetan Plateau and the pressure differences between the northern and southern hemispheres.
    Information Booster:
    • Jet streams are fast-moving air currents in the upper atmosphere, typically found in the tropopause.

    • The Tropical Easterly Jet (TEJ) appears during June to September, centered around 15°N to 20°N latitude.

    • It influences the southwest monsoon circulation over the Indian subcontinent.

    • TEJ flows from east to west.
