    Model Answer

    Barrier Effect

    The Western Ghats serve as a significant barrier to the monsoonal winds that arrive from the southwest. As these winds encounter the mountains, they are forced to rise, resulting in orographic rainfall. This effect leads to substantial precipitation in the region, with 65% to 80% of annual rainfall occurring between June and September (Source: meteorological studies).

    Gaps in the Western Ghats

    Despite their overall barrier function, the Western Ghats feature gaps that allow rain-bearing winds to pass through with less precipitation. A notable example is the Palghat Gap, which is approximately 30 kilometers wide and located between the Nilgiri and Anamalai Hills in Kerala. This gap enables winds to cross over to the leeward side, leading to reduced rainfall in the immediate coastal areas (Source: geographic studies).

    Variations in Mountain Topography

    The topography of the Western Ghats varies significantly. In Karnataka, the broader mountains compel rain-bearing winds to travel greater distances, allowing more time for moisture to coalesce and resulting in higher rainfall (Source: hydrological analyses).

    Increased Convection

    The gentle slopes of the Karnataka Western Ghats absorb more sunlight, promoting greater convection compared to the steeper slopes found in Maharashtra and Kerala. This enhanced convection contributes to increased rainfall in these areas (Source: climate studies).

    Distance from Peak

    Interestingly, areas of heavy rainfall are often found up to 50 kilometers away from the mountain peaks. This phenomenon occurs because the distance allows for better moisture accumulation in cloud formations (Source: meteorological research).

    Cyclones

    Additionally, the Arabian Sea has seen more frequent cyclones in recent years during the onset of the South-West monsoon. The Western Ghats act as a barrier for these cyclonic storms, reducing their intensity and protecting the coastal regions of India (Source: climatological studies).

    In summary, the Western Ghats significantly regulate South-West monsoonal rainfall in India’s coastal regions through orographic lifting, variations in topography, and their role in influencing cyclonic activity.
