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.

。1月16日上午，《北京时间》美国科技媒体TechCrunch援引尼尔森最新报道称，过去8年中，放弃传统有线或卫星电视服务并使用数字天线接收无线电信号的家庭数量增加了48%，达到1600万户。目前，14%的美国家庭通过互联网观看电视节目。

B | 尼尔森说有两种主要类型的人取消了传统的电视服务。一个是年龄较大的观众，平均年龄为55岁。该组只通过数字天线观看电视，不订阅任何流媒体服务。这一群体包括660万家庭，他们更加多样化，中位数收入更低。对他们来说，取消传统的电视服务主要是为了省钱，而不是为了获得个性化的观看体验。

C | 2010年至2018年间，美国940万家庭通过互联网观看电视节目，另外一组940万家庭至少订阅了一个视频服务，如Netflix、Hulu或Amazon Prime Video。这一群体年龄较小，中位数为36岁，收入较高，更喜欢使用网络设备。因为他们使用更多的设备玩游戏或查看社交网络，所以他们花更少的时间观看传统媒体。这也会影响他们看电视的时间。研究发现，在美国家庭中，购买订阅视频服务的人每天通过互联网看电视的时间超过6小时，比那些不购买订阅视频服务的人多2小时。购买视频订阅的人在社交媒体上也更活跃，这可能是因为他们的年龄和设备数量。

D | 他们平均每天花一小时使用社交媒体，比不订阅视频服务的人多17分钟。

E | 在18岁以上的人群中，通过不同频道观看节目的用户比例较高，但两组都喜欢在电视上观看电视内容。尽管智能手机和平板电脑等设备的使用有所增加，但大屏幕电视似乎仍然是电视内容的主要观看设备。此外，购买订阅视频服务的少数互联网观众将使用其他虚拟服务提供商，包括提供直播电视节目的流媒体服务，如YouTube电视、带直播电视的Hulu、PlayStation Vue或Sling电视。截至2018年5月，该群体的总户数已超过130万户。

F | 尼尔森对第三组进行了一项更深入的研究，发现他们拥有大学学位的可能性高出54%，拥有孩子的可能性高出19%，拥有互联网的可能性比普通家庭高出95%。他们也比其他购买视频订阅服务的团体看电视的时间长，分别是3小时27分钟一天和3小时22分钟一天。
