Air quality stays poor, may drop further
NEW DELHI: The air quality of Delhi remained poor on for on Tuesday in Delhi and NCR regions. The weather conditions have changed and also the crop burning has started, both these issues have played a role behind the air quality, said the experts.
The air quality index recorded 250 till 8 PM and the proper pollutants are PM 2.5 and PM 10. An AQI between 0-50 is considered good, 51-100 satisfactory, 101-200 moderate, 201-300 poor, 301-400 very poor, and 401-500 severe.
An official at the Central Pollution Control Board attributed the reason behind the slight improvement on Sunday to less traffic and improvement in wind speed but as the traffic increased on Monday the pollution in the city again rose and the air quality fell.
"So, the prevailing dust in the atmosphere combined with humidity will lead to an increase in pollution level. Thus, mornings and evenings will be hazy," noted Skymet Weather, a private weather forecasting organization. It noted that Pollution will continue to persist for the next few days.
With the presence of trough, Delhi and NCR might experience some thunder activities around October 9 and 10. The rains will be experienced in some parts only. No major relief in day temperatures is expected.
The Deep Depression which was over Southeast and adjoining East-central Arabian Sea has taken a west-northwest track. This has intensified into a Cyclonic Storm Luban and lies over West-central Arabian Sea near Latitude 12.3° N and Longitude 62.4°E, about 1040 km east-southeast of Salalah (Oman). Moreover, these Southwesterly winds from the Arabian Sea will increase the levels of moisture in Delhi- NCR leading to increased levels of humidity. This will eventually lead to the formation of haze.
