Weather Patna: Air Pollution Crisis Intensifies
Patna has been confirmed as the second-most polluted city in India, following Delhi, with persistently high PM2.5 concentrations. The alarming levels of air pollution are significantly influenced by specific weather conditions, particularly during the winter months.
According to a recent study by Climate Trends, Patna’s air quality crisis is driven by strong atmospheric stagnation, which, along with low wind speeds and high humidity, can shift PM2.5 levels by up to 40%. These meteorological factors create an environment where pollution can accumulate, leading to severe health risks for residents.
During the 2024-25 period, Delhi recorded the highest annual PM2.5 levels in India, with extensive periods categorized as ‘severe’ air quality. The Central Pollution Control Board reported that Stage III restrictions were applied for about 53 days in Delhi, while Stage IV measures lasted for around 15 days during severe episodes.
Over 70% of days in both Delhi and Patna fall under low-wind, high-humidity meteorological regimes, which exacerbate the pollution crisis. The Indo-Gangetic Plain, where both cities are located, is particularly vulnerable due to its geography and seasonal weather patterns.
Climate Trends noted, “Delhi continues to face the most severe pollution crisis nationally with the highest annual average PM2.5 levels and the longest stretches of ‘severe’ or ’emergency’ category air days, driven by local emissions and regional factors.” This statement underscores the regional nature of the pollution problem, which also affects Patna significantly.
As the situation evolves, observers are closely monitoring the air quality in Patna and the effectiveness of any measures taken to mitigate pollution. The ongoing crisis highlights the urgent need for comprehensive strategies to address air quality issues in the Indo-Gangetic Plain.
Details remain unconfirmed regarding specific interventions planned for Patna to combat this escalating air quality crisis. However, the need for immediate action is clear as both cities grapple with the health impacts of poor air quality.
