“…The increasing amount of extreme precipitation accounts for 71.6% of the total precipitation increase, implying that the increase of winter extreme precipitation is much larger than that of precipitation in a warming environment in China. This phenomenon coincides with the recent occurrence of many record-breaking snowfall events in China [14][15][16] and with projections of increased winter precipitation and extreme weather events in China in the context of climate warming [17,18].…”

This study analyses the decadal changes in winter precipitation and extreme precipitation in a warming environment in China. The results show that, together with a trend of winter warming in China, winter precipitation and extreme precipitation in the region are also increasing. In addition, concurrent with the decadal warming shift that occurred in the mid-1980s, precipitation and extreme precipitation both increased significantly. Quantitative analysis shows that precipitation and extreme precipitation increased at rates of 9.7% and 22.6% per 1°C of surface warming in China. This rate of precipitation increase is greater than the global mean, which indicates that precipitation in China is highly sensitive to climate warming and further highlights the importance of studying regional responses to climate warming. The fact that extreme precipitation is increasing at a higher rate than precipitation implies that winter precipitation in China will increasingly be of more extreme type in the context of global warming, which could partly explain why there have recently been a number of record-breaking extreme snowfall events in China.winter precipitation, extreme precipitation, global warming, sensitivity, regional response, climate change Citation:Sun

“…All models project increases in the annual precipitation and its related extremes, but large differences are projected in the various magnitudes of these increases. Currently, research involving climate prediction and projection using high-resolution RCMs is underway [34][35][36]. Compared with the couple models, RCMs exhibit improved performance in simulating the regional climate features.…”

Projection of future climate changes and their regional impact is critical for long-term planning at the national and regional levels aimed at adaptation and mitigation. This study assesses the future changes in precipitation in China and the associated atmospheric circulation patterns using the Couple Model Intercomparison Project 5 Phase (CMIP5) simulations under the RCP4.5 and RCP8.5 scenarios. The results consistently indicate that the annual precipitation in China is projected to significantly increase at the end of the 21st century compared to the present-day levels. The number of days and the intensity of medium rain, large rain and heavy rain are obviously increased, while the number of trace rain days is projected to decrease over the entire area of China. Further analysis indicates that the significant increase of annual precipitation in Northwest China is primarily due to the increase of light rain and the increases in North and Northeast China are primarily due to the increase of medium rain. In the region of southern China, the increases of large rain and heavy rain play an important role in the increase of annual precipitation, while light rain events play a negative role. Analysis of the changes in atmospheric circulation indicates that the East Asian summer monsoon circulation is projected to be considerably stronger, and the local atmospheric stratification is projected to be more unstable, all of which provide a background benefit for the increase of precipitation and extreme rainfall events in China under global warming scenarios.

Chin Sci Bull, 2013, 58: 14621472, doi: 10.1007/s11434-012-5612-2The significant warming that has been observed globally over the past century has a high probability of being due to the increase in anthropogenic factors concentrating greenhouse gases. This significant warming has produced a significant impact on human society, ecosystems, and the environment, and this warming is capable of causing thousands of deaths and heavy economic losses. By the end of the 21st century, as reported in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4), human society will become much more vulnerable as the consequences of continuous global warming, with global temperature increasing by 1.1-6.4°C relative to 1980-1999 [1]. Due to these future negative impacts, governments and the public alike have begun to pay increased attention to climate change under the global warming scenario.Modern global climate models that are capable of realistically simulating many aspects of the climate are the primary tools for determining the attribution of recent warming and for developing projections of future climate change. Researchers in China have taken a great deal of effort to study future climate change based on such model simulations, and some valuable and c...

“…The EAWM is closely associated with the Siberia High in low atmosphere, the East Asian Trough in middle troposphere, and the westerly jet stream in high troposphere. In the past years, there has been increased disasters in China resulted by anomalous East Asian winter monsoon and associated snowstorms [2][3][4].…”

The East Asian winter monsoon (EAWM) is characterized by the frequent cold surges and associated closely with the Siberia High, East Asian Trough, and high-level westerly jet stream. The ENSO cycle can modulate the EAWM since it has co-variability with the sea surface temperature over the Indo-Western-Pacific which can tune the land-sea thermal contrast for the EAWM. This paper, by analyzing the EAWM, ENSO, and associated atmosphere-ocean variability, documents the weakening of the EAWM-ENSO relationship after the 1970s. The significant out-of-phase inter-relationship is found to be diminished after the 1970s. Further study in this work suggests that the weakened co-variability of the tropical Indo-Western-Pacific climate associated with ENSO after the 1970s is partly responsible for the weakened inter-relationship. Meanwhile, the reduced EAWM interannual variability and northward retreat of the EAWM-associated climate variability are favorable to the weakened ENSO-EAWM connection.
