Southwest Monsoon Withdraws Early from West Rajasthan
New Delhi: The India Meteorological Department (IMD) has announced that the southwest monsoon has begun its withdrawal from parts of West Rajasthan, occurring three days earlier than the typical date of September 17. This early retreat is attributed to the fulfillment of specific meteorological conditions.
The IMD reported that the monsoon’s withdrawal was facilitated by the development of an anti-cyclonic circulation over West Rajasthan at an altitude of 1.5 kilometers above sea level. Additionally, the region has experienced a lack of rainfall for five consecutive days, coupled with a significant reduction in atmospheric moisture content at mid-tropospheric levels.
Current Conditions and Future Forecasts
The IMD has indicated that the line of withdrawal currently extends through key areas such as Sri Ganganagar, Nagaur, Jodhpur, and Barmer. Favorable conditions are anticipated for the further withdrawal of the southwest monsoon from additional parts of Rajasthan, as well as from regions in Punjab and Gujarat over the next two to three days.
Reports from September 13 suggested that the monsoon might begin its retreat as early as September 15, marking the earliest withdrawal in a decade. If this prediction holds true, it would be the earliest start of withdrawal since 2015, when the monsoon began to recede on September 4. Notably, 2016 also saw a withdrawal commence on September 15.
M. Mohapatra, the Director General of IMD, explained that the declaration of withdrawal is based on the cessation of rainfall, a decrease in humidity, and the presence of anticyclonic winds. He noted that these conditions were expected to manifest over West Rajasthan starting September 15.
Monsoon Performance This Year
This year’s monsoon season commenced in Kerala on May 24, arriving eight days ahead of schedule. The monsoon’s rapid progression across the country was notable, with rainfall levels exceeding expectations. Since June 1, India has recorded an 8% surplus in rainfall overall, with Northwest India experiencing a remarkable 34% excess. Central India saw an 11% increase, while Peninsular India recorded a 7% surplus. However, the eastern and northeastern regions of the country faced a 20% deficiency in rainfall.
Looking ahead, the IMD’s extended forecasts suggest a reduction in rainfall across the country starting September 18, which could have implications for agricultural practices and water resources in the region.
Historical Context of Monsoon Withdrawals
The southwest monsoon is a critical weather phenomenon for India, influencing agriculture, water supply, and overall climate. Traditionally, the monsoon season spans from June to September, with its withdrawal typically occurring in mid-September. The timing of the monsoon’s retreat can significantly impact crop yields and water availability, making it a focal point for farmers and policymakers alike.
Historically, variations in monsoon patterns have been linked to broader climatic changes, including El Niño and La Niña phenomena, which can alter weather patterns across the globe. The early withdrawal of the monsoon this year may raise concerns about the potential for drought conditions in the coming months, particularly in regions that rely heavily on monsoon rains for irrigation.
Implications for Agriculture and Water Resources
The early retreat of the southwest monsoon could have mixed implications for agriculture in West Rajasthan and surrounding areas. While some farmers may benefit from the timely cessation of rains, allowing for the harvesting of kharif crops, others may face challenges if the subsequent dry spell is prolonged. The agricultural sector, which employs a significant portion of the Indian population, is particularly sensitive to fluctuations in monsoon patterns.
Moreover, water resource management will be crucial in the coming months. With the monsoon’s early withdrawal, authorities may need to implement strategies to conserve water and ensure adequate supply for both agricultural and domestic use. This could involve measures such as rainwater harvesting, groundwater recharge, and efficient irrigation practices.
Conclusion
The early withdrawal of the southwest monsoon from West Rajasthan marks a significant meteorological event, with potential implications for agriculture, water resources, and climate patterns in the region. As the IMD continues to monitor conditions, stakeholders across various sectors will need to adapt to the changing weather dynamics. Understanding the nuances of monsoon behavior is essential for effective planning and resource management in a country where agriculture remains a cornerstone of the economy.
