The Western Ghats


The Western Ghats extend from the Satpura Range in the north, go south past Goa, through Karnataka and into Kerala and Tamil Nadu. The major hill range starting from the north is the Sahyadhri (the benevolent mountains) range. This range is home to many hill stations like Matheran, Lonavala-Khandala, Mahabaleshwar, Panchgani, Amboli Ghat, Kudremukh and Kodagu. The range is called Sahyadri in northern Maharashtra and Sahya Parvatam in Kerala. The Bili giri rangana Betta southeast of Mysore in Karnataka, meet the Shevaroys (Servarayan range) and Tirumala range farther east, linking the Western Ghats to the Eastern Ghats.

In the south the range is known as the Nilagiri malai in Tamil Nadu. Smaller ranges, including the Cardamom Hills and the Nilgiri Hills, are in northwestern Tamil Nadu. The Nilgiri Hills are home to the hill station Ootacamund. In the southern part of the range is the Anaimalai Hills, in western Tamil Nadu and Kerala. Ana Mudi 2,695 metres (8,842 ft) in Kerala is the highest peak in Western Ghats. Chembra Peak 2,100 metres (6,890 ft), Banasura Peak 2,073 metres (6,801 ft), Vellarimala 2,200 metres (7,218 ft) and Agasthya mala 1,868 metres (6,129 ft) are also in Kerala. Doddabetta is 2,637 metres (8,652 ft). Mullayanagiri is the highest peak in Karnataka 1,950 metres (6,398 ft). The Western Ghats in Kerala is home to many tea and coffee plantations. The major gaps in the range are the Goa Gap, between the Maharashtra and Karnataka sections, and the Palghat Gap on the Tamil Nadu/Kerala border between the Nilgiri Hills and the Anaimalai Hills.

The northern portion of the narrow coastal plain between the Western Ghats and the Arabian Sea is known as the Konkan Coast or simply Konkan,the central portion is called Kanara and the southern portion is called Malabar region or the Malabar Coast. The foothill region east of the Ghats in Maharashtra is known as Desh, while the eastern foothills of the central Karnataka state is known as Malenadu. The largest city within the mountains is the city of Pune (Poona), in the Desh region on the eastern edge of the range. The Biligirirangan Hills lies at the confluence of the Western and Eastern Ghats.

The mountains intercept the rain-bearing westerly monsoon winds, and are consequently an area of high rainfall, particularly on their western side. The dense forests also contribute to the precipitation of the area by acting as a substrate for condensation of moist rising orographic winds from the sea, and releasing much of the moisture back into the air via transpiration, allowing it to later condense and fall again as rain.
