SAFAR-Air Quality Forecast :     (1) Delhi: The overall Delhi air quality has improved to the Moderate category.Surface winds are high and west southwesterly. Increased surface wind speed, higher temperature, and higher boundary layer heights are influencing AQI positively. The winter fury appears to be over but now Delhi air will start getting influenced by mineral dust and immediate issue is the transport of dust from dry desert regions of Rajasthan under the influence of induced cyclonic circulation and increased wind speed. An increase in mineral dust contribution is expected in the coming days. Hence, AQI is forecasted to fall in Poor category in the next two days in spite of good ventilation and favourable local weather parameters.         (2) Mumbai, Pune, and Ahmedabad: The air quality of Mumbai is in moderate category and will remain in moderate condition for the next 2 days because of increased ventilation. The AQI of Ahmadabad is in the moderate category and will degrade and remain in moderate to poor category due to dust for next 2 days. The AQI of Pune is satisfactory category and predicted remain in upper end of satisfactory category for the next 3 days.

Increased surface wind speed, higher temperature, and higher boundary layer heights are influencing AQI positively. The winter fury appears to be over but now Delhi air will start getting influenced by mineral dust and immediate issue is the transport of dust from dry desert regions of Rajasthan under the influence of induced cyclonic circulation and increased wind speed. An increase in mineral dust contribution is expected in the coming days.

The AQI of Ahmadabad is in the moderate category and will degrade and remain in moderate to poor category due to dust for next 2 days. The AQI of Pune is satisfactory category and predicted remain in upper end of satisfactory category for the next 3 days.

  FACTORS AFFECTING DELHI AIR QUALITY :

  RED Line: Most Influencing factor forecasted to deteriorate AQI

(1)  STUBBLE BURNING IMPACT: LOW

(2)   MIXING LAYER HEIGHT:MODERATE

(3)  LOCAL WIND SPEED: HIGH

  IMPACT: HIGH DISPERSION

(4)  EXTERNAL DUST IMPACT: LOW
