BRICS 2026: Delhi Gets A Pollution Break With Putin, Xi, Pezeshkian In Town AQI Falls To 62 - What Cleaned The Air?

(MENAFN- Live Mint) Delhi is welcoming several of the world's most prominent leaders this weekend as the BRICS Summit takes place in the capital. Amid the high-profile gathering, Delhi has also recorded a noticeable improvement in air quality.

At around 4 pm on September 12, Delhi's lowest AQI reading was recorded at 62, putting it in the moderate category, according to AQI.

The improvement in air quality comes as Chinese President Xi Jinping, Russian President Vladimir Putin and other BRICS leaders arrive in Delhi for the two-day summit.

Quick answers to key questions

.5 QUESTIONS1What factors contributed to the improvement of Delhi's air quality during the BRICS Summit?⌵

The improvement in Delhi's air quality, with an AQI of 62, was primarily due to recent rainfall and overcast skies from an active monsoon, which helped wash away suspended pollutants.

2How does rainfall affect air quality in urban areas like Delhi?⌵

Rainfall enhances air quality by capturing dust and pollutants as raindrops fall, reducing the concentration of airborne particles in urban settings.

3What key topics were discussed at the BRICS Summit in New Delhi?⌵

The BRICS Summit focused on global trade, energy security, conflict prevention, and the need for reform in global governance and financial institutions.

4Why is the timing of the BRICS Summit significant for Delhi's air quality?⌵

The BRICS Summit coincided with a period of unusually clean air for Delhi, influenced by favorable weather conditions, which helped create a more agreeable environment for the high-profile gathering.

5What are the implications of the New Delhi Declaration adopted at the BRICS Summit?⌵

The New Delhi Declaration emphasizes collective efforts for global governance reform, conflict prevention, and the rejection of unilateral economic sanctions, reflecting a commitment to cooperation among BRICS nations.

The change is notable because the capital had recorded comparatively higher pollution levels earlier this week. Delhi's official AQI was 133 on September 10, which was also in the moderate category. The reading had risen further to 155 during the early hours of Friday, September 11.

So, what has helped clear Delhi's notoriously polluted air? The answer largely lies in the weather conditions.

The capital has experienced rainfall and overcast skies in recent days as an active monsoon spell continues to influence the region.

The India Meteorological Department (IMD) had predicted generally cloudy conditions accompanied by moderate rain in Delhi on September 12. The wet weather is also expected to persist over the coming days.

Rainfall can provide a temporary boost to air quality by washing some suspended pollutants out of the atmosphere. As raindrops move towards the ground, they can capture dust and other pollution particles present in the air.

Changes in wind patterns and atmospheric conditions can further aid the dispersion of pollutants, preventing them from accumulating near the surface.

The ongoing weather conditions are also linked to a broader monsoon system. A low-pressure area over the northwest and west-central Bay of Bengal is influencing rainfall across several parts of northern and central India, including Delhi.
