As sea surface temperatures in the equatorial central‑eastern Pacific are expected to peak around November to December, potentially leading to a record-strong super El Nino event, China has already experienced typical El Nino-related climate patterns this summer, the China Meteorological Administration announced on Tuesday. These include two major rain belts in eastern regions that caused widespread and intense storms with overlapping impacts, as well more frequent and stronger typhoons delivering prolonged wind and rain.
The central and eastern equatorial Pacific entered an El Nino phase in May, and sea temperatures have since surged. The monitoring region’s sea surface temperature index 2.09 C in July, up 0.49 C from June. By mid-August, it had climbed to 2.64 C, signaling an unusually fast warming trend, the CMA said.
However, according to China’s national standard, a super El Nino event has not yet officially formed.
Given the current pronounced warming trend, a super El Nino event is highly likely to occur, with its intensity potentially exceeding that of the three strongest events on record in 1982-83, 1997-98, and 2015-16 and making it the strongest one ever observed, according to the CMA.
Since the start of summer, China’s abnormal climate patterns have reflected the typical impacts of the El Nino. The western Pacific subtropical high and the monsoon trough have shifted farther north and become stronger, while upper-level cold vortices have repeatedly moved into northern China, resulting in two major rain centers in the north and south, the CMA said.
A stronger summer monsoon has contributed to more frequent and intense typhoon activity, bringing heavier rainfall to southern China and the lower Yangtze River. In northern China, the northward-shifted subtropical high, frequent cold vortices and long-range moisture transport through the typhoons have contributed to repeated strong winds and heavy rain, according to the CMA.
According to CMA, as El Nino continues to develop rapidly and its impacts tend to lag behind its development, the National Climate Centre will strengthen monitoring and forecasting efforts, while closely tracking its future evolution and potential impacts on China’s climate.

China's cybersecurity authority unveiled cases involving the fabrication and online spread of flood and disaster-related rumors on Monday. The cases included netizens fabricating misinformation using AI to garner attention, even extending to creating doctored official government advisories, China Central Television (CCTV) News reported.
A total of 15 typical cases were made public by the cyberspace authority under China's Ministry of Public Security, as part of a continued drive against illegal activities involving the creation and spread of disaster-related false information that disrupt social order.
Several of these rumors were crafted with AI tools. For instance, a 37-year-old male netizen based in Shenzhen, South China's Guangdong Province, doctored local official typhoon safety notices using AI, posting the manipulated versions on social media to garner views. The false posts drew widespread public discussion and impacted disaster relief operations.
A netizen surnamed Yang from Qingyuan, Guangdong Province, used AI to create false notices claiming local school closures, work and business shutdowns amid flooding, disseminating them via WeChat.
Two other netizens similarly utilized AI tools to generate and circulate similar instances of disinformation using Douyin, alleging that in one case a food-delivery courier was still required to complete 10 deliveries during the typhoon and was seen clinging to a utility pole as strong winds swept him off the ground.
All individuals implicated in these publicly disclosed cases have been subject to administrative penalties by local public security authorities in accordance with the law, CCTV reported
In addition, some netizens fabricated false information from scratch. For instance, one netizen invented a story claiming that a flash flood had killed over 100 people and that rescue efforts had failed, purely to gain online traction.
Others resorted to deceptive editing techniques, including one individual who clipped and spliced together footage downloaded from the internet that had no connection to the typhoon, falsely presenting it as "a person trapped on a tower crane during the typhoon" and posting it on social media.
These netizens have been issued administrative penalties by local public security authorities according to law.
