Delhi is experiencing alarming levels of air pollution over the past six days and its getting difficult to breathe at the national capital.

Though the policy measures to mitigate the crisis have not yielded much in containing the situation, especially due to stubble burning in the nearby states of Punjab and Haryana, as reported by HindustanTimes.

With restrictions under stage 4 of the Graded Response Action Plan (GRAP) in place, and the odd-even curb on vehicular movement in the offing, a western disturbance (WD) seems to have also come to the city’s rescue, weather officials said.

The weather pattern, which is impacting the Western Himalayan region, has led to a southeasterly shift in the wind direction. This has also led to an increase in wind speed of around 5kmph from calm conditions (0 speed) around 6am on Tuesday morning. The minor increase in wind speed has led to a marginal reduction in air pollution levels over the National Capital Region.

Delhi NCR may receive very light rain or drizzles during this period. The wind direction moved southeasterly on Monday and on Tuesday it varied between northwesterly and southeasterly. When the winds move in the southeasterly direction, the impact of stubble fires in Punjab and Haryana on northwest Delhi will not add to the existing pollution levels in the national capital.
