Javadhu Hills

The hills consist of bluish-grey granites, with peaks averaging 3,800–4,000 feet (1,300–1,350 m). About 50 miles (80 km) wide and 20 miles (32 km) long, they are bisected into eastern and western sections by the Cheyyar and Agaram rivers, tributaries of the Palar. "The Barahmahal hills to the west are somewhat bare, but the Jawadhi are clothed in verdure to the very summit on the east: towards sunset the whole range puts on a purple tinge like heather bloom. The sharper shadows mark out minor ranges and valleys, which in the midday merge in the mass of the range, and beyond Bommaikuppam, looking from Tirupatur, a silvery cascade may be seen, shining bright in the setting sun.". 8 During the British colonisation of India, the Javadhu Hills appeared occasionally in government gazetteers and manuals, ethnographies, and travelers' accounts. Henry le Fanu, writing in 1883, admired the beauty of the Jawadhi hills.

The Indian astronomer Vainu Bappu selected the hills as the site of the Kavalur Observatory (VBO), which began operations in 1967.

Significance

The Javadi Hills, also known as Jawadhu Hills, are indeed significant in influencing weather patterns in the surrounding districts of Tamil Nadu, including Vellore, Ranipet, Tirupattur, Chennai, Kanchipuram, Tiruvallur, and Chengalpattu. These hills contribute to the formation of thunder and rain clouds due to their elevation and geographical features, making them a critical area for rainfall production in the region.

The Javadi Hills, part of the Eastern Ghats, are indeed an important geographical feature. They mark the end of the Deccan Plateau and play a crucial role in weather patterns, particularly in rain cloud formation. The hills' elevation and location contribute to the strength and prevalence of the clouds that form there, impacting the weather in the surrounding districts.
