La Ni a event to end in early spring: China national climate center

China's national climate center has forecast that the ongoing La Ni a event, which causes climate chaos, will come to an end early in the spring this year.

La Ni a refers to the large-scale cooling of ocean surface temperatures in the central and eastern equatorial Pacific Ocean, coupled with wind, pressure and rainfall changes in tropical atmospheric circulation.

The abnormal, cooler subsurface water of the middle and eastern equatorial Pacific Ocean clearly weakened in December 2022, the National Climate Center said, yet the La Ni a-like atmospheric pattern remained.

The La Ni a event in the middle and eastern equatorial Pacific Ocean has continued since January this year, but is likely to end early in the spring, according to the climate center's monitoring work.
