• The wind flowing in the northern plains in summers is known as 'loo'.
  
• Loo is a strong hot and dry winds that blows over the western Indo-Gangetic plain of North India and Pakistan.
  
• It is especially strong in the months of May and June.
  

Indian sub-continent is divided into plains, plateaus and mountains.

• Delta region is formed by deposition of sediments carried by rivers. In such regions alluvial soil is mostly formed.
  
• Alluvium is a loose soil or sediments which are formed by erosion by rainwater. It is typically made of small particles of silt and clay and larger particles of sand and gravel.
  

• Rajasthan receives scanty rainfall and hence experience severe famine.
  
• Scarcity of rainfall is due to following reasons:
  
• South-east monsoon arriving from Bay of Bengal loses its moisture by the time it reaches north-western part of India where Rajasthan is located.
  
• And the south-west monsoon arriving from Bay of Bengal flows parallel to the Aravalli mountains and reach north-east part of India.
  

The Western part of Rajasthan is a desert because the temperature remains very high in summer and the Aravallis lie parallel to the path of the Arabian Sea Branch of the southwest monsoons , there by causing no orographic rainfall. When there is an excess moisture in cloud that cannot hold it further and sudden upliftment of cloud with same moisture. As cloud moves suddenly upwards it looses it moisture holding capacity. This happens in windward side of mountain. These Aravalli range are not blocking winds which carry moisture. They are parallel to the direction of cloud movement, so there is no upliftment of clouds carring moisture, so there are very little rains in Rajasthan. Thus the deserts are formed.

•  The Kali Andhi, or black storm is a violent, squally dust storm occuring  in late spring in north-western India.
  
•  They are usually brief, but can block out the sun, drastically reduce visibility and cause property damage and injuries.
  
•  The Andhi heralds the imminent arrival of the monsoon .
  
• Andhi is seen Punjab, Rajasthan in India, a summer time blowing, it is also called sand wind.

• Below the Tista, the Brahmaputra splits into two distributary branches. 
  
• The western branch, which contains the majority of the river's flow, continues due south as the Jamuna (Jomuna) to merge with the lower Ganga, called the Padma River (Pôdda).
  
• It is the main distributary channel of the Brahmaputra River as it flows from India to Bangladesh. The Jamuna flows south and joins the Padma River (Pôdda), near Goalundo Ghat, before meeting the Meghna River near Chandpur. It then flows into the Bay of Bengal as the Meghna River.
