As if China's extreme weather hasn't been abnormal enough, experts are warning that the temperature might be severely cold this winter.

The immediate cause was abnormal changes in general air circulation and global warming, Jiao Meiyan, deputy chief of China Meteorological Administration, said yesterday.

Many Chinese cities were hit by massive rainfalls and extreme heat in the past eight months. In particular, Jiao noted the massive mudslide in Gansu Province this month, which was triggered by excessive rainfalls after a strong cold front moved southward.

There was also the record-long drought that baked the southwest Yunan and Guizhou provinces, costing millions of hectares in crops, attributed to a strong and prolonged subtropical high pressure.

Global warming caused by greenhouse gases emitted by human activity was the other major contributing factor, pushing the temperatures to record highs in many countries, Jiao added.

China was not alone in the weather chaos; the extremes appeared around the globe.

While Pakistan was battered by its worst flood, summer heat waves scorched the eastern United States, Africa and Russia.

Jiao said the weather in China this year was very much like that in 1998, a year that saw the power of El Nino and La Nina, distinctive climate patterns that have close connections with massive droughts and floods.Source: Shanghai Daily
