Question Discussion & Solution

The correct answer is Winter rain.

• Popularly known as 'Mavath' in Rajasthan is Winter Rain.

Additional Information 

• During the winter, the flow of air reverses.
• The continent cools rapidly forming a large area of high pressure over north-central Asia, known as the Siberian High, and a smaller area over India.
• Now, the drier, colder air of the continent blows offshore creating the dry monsoon season.
• Many parts of southern India receive considerable rain from the northeast monsoon.
• Though the principal rainy season for interior Karnataka, Kerala and Lakshadweep is the Southwest Monsoon season, rainfall continues till December in these regions.
• Tamilnadu, in particular, typically gets nearly half its annual rain during this monsoon.

The correct answer is In the districts of Ganganagar & Hanumangarh.

Key Points

• 'Ghagghar ka Maidan' is situated in the districts of Ganganagar and Hanumangarh.
• The Ghaggar-Hakra River is an intermittent river in India and Pakistan that flows only during the monsoon season.
  • The river is known as Ghaggar in India, before the Ottu barrage, and as the Hakra in Pakistan, downstream of the barrage, ending in the Thar desert.
• In pre-Harappan times the Hakra was a tributary of the Sutlej.
  • It is still connected to this paleochannel of the Sutlej, and possibly the Yamuna, which ended in the Nara River, presently a delta channel of the Indus River joining the sea via Sir Creek.

Additional Information

• The Ghaggar is an intermittent river in India, flowing during the monsoon rains.
  • It originates in the village of Dagshai in the Shivalik Hills of Himachal Pradesh at an elevation of 1,927 meters (6,322 ft) above mean sea level and flows through Punjab and Haryana states into Rajasthan just southwest of Sirsa, Haryana, and by the side of Talwara Lake in Rajasthan.
  • Dammed at Ottu barrage near Sirsa, Ghaggar feeds two irrigation canals that extend into Rajasthan.
• The main tributaries of the Ghaggar are the Kaushalya river, Markanda, Sarsuti, Tangri and Chautang.
• The Kaushalya river is a tributary of Ghaggar river on the left side of Ghaggar-Hakra,
• It flows in the Panchkula district of Haryana state of India and confluences with Ghaggar river near Pinjore just downstream of Kaushalya Dam.

Key Points

• In the summer season-low, air pressure area of Rajasthan is found in the North-Western region.

Additional Information 

• The low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations.
• Low-pressure systems form under areas of wind divergence that occur in the upper levels of the atmosphere.
• The formation process of a low-pressure area is known as cyclogenesis.
