China might have to burn more fossil fuels this year as meteorologists forecast a moderate-or-stronger El Nino weather event in the summer and autumn, which could disrupt operations at hydropower stations across the region at a time when fuel supplies from the Middle East are disrupted.
China's National Climate Centre expects El Nino conditions to emerge in May and said an El Nino event would last at least through the end of the year, according to an analysis published by the China Meteorological Administration over the weekend.t
El Nino is a natural weather pattern linked to a warming of the central and eastern Pacific, bringing heavier rainfall to the Pacific coast of the Americas. In the Western Pacific, the shift can disrupt the East Asian monsoon, raising the odds of flooding in southern China and drought in other Chinese regions.
Flooding caused by a severe El Nino event can damage power grid infrastructure, while both excessive rainfall and drought can require hydropower dams to reduce or even halt output, senior meteorologist Wang Yaqi said in the CMA's analysis. El Nino can have a severe impact on hydropower-dependent regions, Wang added.
