A major update regarding the onset of the monsoon in India has emerged. It is reported that monsoon rains in India might begin ahead of schedule this year. Additionally, significant changes in wind circulation patterns are anticipated in the coming days.
Advanced extended forecasts from major global NWP modeling centers suggest that the monsoon could arrive early in the South Asian region, including India. Rapid changes in large-scale wind circulation patterns are expected in the upcoming weeks, involving semi-permanent features associated with the Asian monsoon circulation over the tropical Indian Ocean.
Monsoon to Arrive Soon in Andaman and Nicobar
Monsoon rains in the Andaman and Nicobar Islands might begin as early as mid-May. The meteorological department predicts the monsoon's arrival by May 13 in these regions. Kerala may then witness the onset of the monsoon with rains by the last week of May.
Analyses of anomalies at sub-seasonal scales, along with outputs from NWP-based models, indicate that moist equatorial waves such as equatorial Rossby waves might either advance or be quasi-stationary.
In the coming days, these could start affecting the weather patterns over the Indian region, thereby potentially accelerating the monsoon's arrival.
Benefits for Agriculture and Water Resources
Experts suggest ongoing monitoring and real-time analysis over the next few days will bring more clarity. An early monsoon could significantly benefit agriculture and water resource management.
