Introduction:
The Ganga-Brahmaputra basin area, located in the northern part of India, is dominated by a monsoon climate. The monsoon season brings significant rainfall to this region, which is crucial for agriculture and the overall economy of the area. Understanding the timing of the monsoon season is important for planning agricultural activities and water resource management.
Explanation:
The correct answer is option 'B' - the monsoon in the Ganga-Brahmaputra basin area typically lasts from mid-June to mid-September. Let's explore why this is the case:
1. Monsoon Season:
The monsoon season is characterized by a shift in wind patterns, bringing moist air from the Indian Ocean to the Indian subcontinent. The Ganga-Brahmaputra basin area is located in the path of the southwest monsoon, which is the primary monsoon season in India.
2. Onset of the Monsoon:
The southwest monsoon typically arrives in Kerala, in the southern part of India, around the end of May or early June. From there, it progresses northwards, covering the entire country over a period of time.
3. Progression of the Monsoon:
As the monsoon progresses, it moves towards the Ganga-Brahmaputra basin area. The monsoon winds encounter the Himalayan mountain range, causing them to be forced to rise and cool. This process leads to heavy rainfall in the foothills of the Himalayas and the surrounding plains.
4. Duration of the Monsoon:
The monsoon season in the Ganga-Brahmaputra basin area lasts for about four months, from mid-June to mid-September. This period is characterized by frequent rainfall and high humidity.
5. Importance of Monsoon Rainfall:
The monsoon rainfall is crucial for agriculture in the Ganga-Brahmaputra basin area. It replenishes the soil moisture, which is essential for crop growth. The rivers in the region are also heavily dependent on monsoon rainfall, as they receive a significant portion of their water during this season.
Conclusion:
In conclusion, the Ganga-Brahmaputra basin area experiences a monsoon climate, with the monsoon season lasting from mid-June to mid-September. The monsoon rainfall during this period is vital for agriculture and the overall economy of the region. Understanding the timing of the monsoon is crucial for effective water resource management and agricultural planning in this area.
