The Australian Bureau of Meteorology has said that the chances of El Nino weather phenomenon occurring in 2015 have increased to 70% from 50%.

El Nino is a temporary change in the climate of the Pacific ocean, in the region around the equator. Its effects can be seen in both the ocean and atmosphere, generally in Northern Hemisphere winter. Typically, the ocean surface warms up by a few degrees Celsius. At the same time, the place where hefty thunderstorms occur on the equator moves eastward. Although those might seem like small differences, it nevertheless can have a big impact on the world’s climate.

A statement issued by the bureau on April 14th said that, “The ENSO Tracker has been raised to El Nino Alert, indicating at least a 70% chance of El Nino occurring this year.”

It was also revealed in the statement that all the international climate models observed by the bureau signify that El Nino thresholds will be reached or exceeded by June.

“Tropical Pacific Ocean sea surface temperatures are now just shy of El Nino levels. Large areas of warmer-than-average water below the surface are likely to keep these waters warm for some time. This increases the odds of atmospheric factors coming into play, and hence further warming of the tropical Pacific Ocean,” the statement said.

However, it is expected that April to June will be wetter than average across much of Australia owing to warm conditions in the Indian Ocean.

The National Capital and the regions around it continue to suffer a “very-poor” air quality on Friday, which according to experts, may worsen due to combined effects of Dussehra and meteorological reasons such as low winds in Delhi.

Between 6pm to 8pm, over 48 areas across the National Capital Region — 36 from Delhi alone — suffered ‘very poor air-quality’ with pollutants registering over four times the national safety standards.

Weather analysts say this may worsen as Delhi currently has very light variable winds with no definite directions, which is likely to help in aggregating the pollutants.

“Delhi has a negligible wind speed and morning temperatures are low. Also, many effigies were burnt across the region on Dussehera. This will push up the pollution levels,” said Mahesh Palawat, director private weather forecasting group, Skymet.

The air-quality was already ‘severe’ at Anand Vihar in east Delhi and Rohini in north Delhi, Bawana in northwest Delhi, Mundaka in West Delhi and Bhiwadi in Rajasthan, acoording to the real-time monitoring taken up around 8pm by Central Pollution Control Board (CPCB).

The average presence of major pollutant PM2.5 or particle with diametre less than 2.5mm, was 129 unit across Delhi-NCR and 133 units in Delhi, which is more than twice the national safe limits. Rohini was the most polluted with PM2.5 concentration at 166 units, about three times the safe limits.

The permissible range or PM2.5 is 60 as per national standards and 25 by the international standards.

At 4pm, the Air Quality Index (AQI) of Delhi was 276 marked ‘poor’ against ‘moderate’ mere 48 hours back.
