Recently, the World Meteorological Organization released its latest global seasonal climate update, forecasting that from October to December this year, sea surface temperatures in the Niño 3.4 region, a key monitoring area for El Niño, will be 3.7°C higher than usual, peaking around December, with the phenomenon nearly 100% likely to persist until February 2027.

Stay alert to localized abnormal rainfall: both drought and flood risks coexist in northern and southern China

El Niño disrupts atmospheric circulation and water vapor transport, and China's climate pattern will be profoundly affected. Some regions will see surging rainfall, while others will suffer drought, with both north and south facing challenges.

From October to December, southern China should be alert to concentrated rainfall and rapidly rising river levels; the north needs to closely monitor localized abnormal rainfall, with river channels, reservoirs, and embankments inspected in advance.

Yan Denghua, chief engineer of the Disaster Reduction Center at the China Institute of Water Resources and Hydropower Research, said that recently both flood control and drought relief must be addressed simultaneously. It should not be rigidly assumed that old drought-prone areas only need to focus on drought relief and flood-prone areas only on flood control; both north and south need to prepare on two fronts.

El Niño amplifies the suddenness of rainfall. When land that has long suffered drought encounters multiple rounds of heavy rainfall, it quickly experiences "drought first, then flooding," putting enormous pressure on farmland drainage, river flood conveyance, and reservoir operation.

Qin Tianling, director of the Aerospace Intelligent Research Office at the Disaster Reduction Center of the Ministry of Water Resources, said that heavy rainfall may be concentrated in small rivers and small mountain gully areas, with water levels surging in a short time. It is not enough to look only at large-scale rainfall data for an entire city or province.

Super El Niño event stirs South America; 2027 may become the hottest year on record

Currently, a super El Niño event has officially formed. This climate phenomenon disrupts global atmospheric circulation, triggers multiple extreme weather events, and brings sharply different climate impacts to South American countries: some areas are battered by torrential rain with soaring flood risks, while other regions see worsening drought.

El Niño is a natural climate phenomenon whose core manifestation is abnormal warming of sea water in the central and eastern equatorial Pacific. Industry experts warn that this round of super El Niño will further raise the global average temperature.
