India is on course for its driest monsoon in 17 years as a strengthening El Nino curbs rainfall, threatening crop yields and raising food-price risks.
That could potentially bring much-needed rain to eastern and northeastern India, mitigating the deficit there, he added. Cumulative rainfall during the June to September monsoon season is 15% below the long-term average so far, according to the India Meteorological Department. If the deficit persists, it would be the weakest monsoon since 2009, when precipitation was 18% below normal. The weather office had forecast a 10% shortfall for this season back in May.
Conditions may become favorable for a tropical cyclone in the Bay of Bengal in the last week of September, said Christian Werner, managing director of Australia-based consultancy Global Weather Climate Analytics.
Forecasters and academics are also placing bets on India’s monsoon through a specialty prediction platform at Lancaster University in the UK, known by its acronym CRUCIAL. Adequate monsoon rains are crucial for the hundreds of millions of Indian farmers who depend on the seasonal precipitation to irrigate fields in the country, which is among the world’s biggest producers of rice, sugar and cotton. The season accounts for most of India’s annual rainfall.
With less than two weeks of monsoon remaining, the platform is assigning a 68% chance that the season will end with a rainfall deficit of 10% to 20%, according to founder and planetary scientist Mark Roulston. When the monsoon is deficient, every 1 percentage-point shortfall in precipitation from normal levels typically raises food inflation by about 25 basis points, according to Yuvika Singhal, an economist at QuantEco.
