What is causing flight disruptions in India?

Flight disruptions in India are caused by a volcanic ash plume moving across the region from an eruption.

Will the volcanic ash affect Delhi's air quality?

The volcanic ash is primarily at high altitudes, so significant impact on Delhi's air quality is unlikely, though some haze is expected.

When is the volcanic ash expected to reach India?

The volcanic ash has already begun to impact Indian airspace and is expected to move across northern India in the coming hours.

Volcanic ash may cause a slight temperature rise and affect air quality.

Volcanic Ash Threatens Indian Skies, Flights Disrupted

An ash plume originating from a volcanic eruption is currently progressing towards northwestern India, leading to immediate impacts on airspace operations. The ash cloud, characterized by fine rock particles and sulphur dioxide reaching altitudes of 10-15 kilometers, is expected to affect regions including Gujarat, Rajasthan, Delhi-NCR, and Punjab. This atmospheric phenomenon has already prompted airlines to cancel and reroute flights, with further disruptions anticipated.

Meteorological experts noted the plume's rapid movement across Central Asia into India. While the ash is primarily at upper atmospheric levels, it may cause a marginal increase in surface temperatures, akin to cloudy conditions. The potential impact on air quality remains uncertain, though significant surface-level effects are deemed unlikely.
