Anthropogenic Heat Flux Increases the Frequency of Extreme Heat Events
January 14 - December 31
Anthropogenic, or human-made, heat flux in the near-surface atmosphere has changed urban thermal environments. Much of this fluctuation has been noted with rapid development of the global economy and urbanization since the turn of the 21st century. Meanwhile, the number of extreme temperature events in the first decade of the 21st century grew faster than in the last 10 years of the 20th century. During this period, urban extreme heat events have become more frequent, breaking temperature records more often.
“We found the relationships between anthropogenic heat flux and extreme temperature events…” said Prof. XIE Zhenghui, a scientist with the Institute of Atmospheric Physics, Chinese Academy of Sciences. “…including both extreme cold and heat events, based on seven extreme temperature indices by conducting the advanced model.”
