The paper “Evolution of land surface air temperature trend” cooperatively finished by Professor Huang Jianping’s research team from Lanzhou University and Professor Wu Zhaohua’s research team from Florida State University was published on Nature Climate Change, a journal affiliated to the world-renowned Nature.
Ji Fei, the first author of the paper, is a doctoral student guided by Professor Huang. The research started in 2011, and in September 2012, Ji Fei, as a joint training doctoral student, went to Florida State University for further study and continued this research under the guidance of Professor Wu Zhaohua.
Analyzing the evolution of global land surface air temperature trend in the past century, the paper pointed out that the land surface air temperature trend has evolved since 1900. From a zonal average perspective, noticeable warming first took place in the subtropical and subpolar regions of the Northern Hemisphere, followed by subtropical warming in the Southern Hemisphere. The fastest warming in recent decades occurred in northern mid-latitudes.
Professor Huang has found in as early as 2012 that the global arid and semi-arid region warming trend was enhanced, especially in the boreal cold season over semi-arid regions, not primarily caused by the increase of greenhouse gases, but by local land surface processes, changes in snow and frozen soil cover, and human activity, whose contributions still can’t be clarified in the climate change. Professor Huang’s finding in this aspect has attracted global attention. The project “Climate Change and Its Impact in Typical Global Arid and Semi-Arid Region” chaired by Professor Huang Jianping is funded by major national scientific research projects.
This paper is fully funded by the project and its conclusions are one of the major achievements of the project. The paper further confirms Professor Huang’s research on accelerated warming in semi-arid regions.
