“…The TP is the headwater for the largest rivers in Asia, such as Yellow, Yangtze, and Mekong, and plays a significant role in the hydrological cycle of surrounding countries by reserving water in the forms of snow, glaciers, and permafrost (Ma et al, 2017). Almost half of the FT climate area is expected to be changed to various other climate types under the 2°C GWL and one more degree warming from 2°C GWL can double the distinction of the FT climate zone, which will reach 100% extinction if we follow the RCP8.5 scenario at the end of the 21st century.…”

For the comprehensive estimation of regional climate change over East Asia (EA) at the 2 and 3°C global warming levels (GWLs), the Köppen-Trewartha climate-type change is assessed with ensemble regional climate change projections in line with Coordinated Regional Climate Downscaling Experiment (CORDEX)-EA phase 2. Under the 2°C (3°C) GWL, 17.6% (25.2%) of the EA region is expected to undergo major climate-type changes. Tropical and subtropical climate types will expand northward, accompanied by increasing hydroclimatic intensity. Limiting GWL to 2°C shows benefits by preventing subtropical-type expansion around far EA. Desertification over inland regions of EA exhibits scenario dependency. Boreal and tundra climate types over high-latitude regions will tend to decrease rapidly, especially over the Tibetan Plateau. The results are expected to be a baseline assessment of climate change over EA under the 2 and 3°C GWLs above the preindustrial level.Plain Language Summary This paper investigates the Köppen-Trewartha climate-type changes over East Asia (EA) at the 2 and 3°C global warming levels (GWLs) with the ensemble regional climate simulations. Under the 2°C (3°C) GWL, 17.6% (25.2%) of the EA region is expected to undergo major climate-type changes. The result shows increased tropical, subtropical, and desert climate types accompanied by intensification of hydroclimatic stress. In addition, boreal and tundra climate types over high-latitude regions will tend to decrease rapidly, especially over the Tibetan Plateau under the 2 and 3°C GWLs.

“…With extensive glaciers and permafrosts, the TP is the source of many rivers in Asia, which is called as the "Asian Water Tower" (Cui et al 2015;Duan et al 2011;Yao et al 2012;You et al 2013bYou et al , 2016b. In addition, it has profound influences on not only the local climate but also the climate of the Asian continent, even on the global climate through its thermal and dynamic forcing (Duan et al , 2013Ma et al 2014b;Wu and Zhang 1998). It also strongly influences the environmental changes in China, Asia, and even the Northern Hemisphere (Guo and Wang 2013;Shen et al 2015;Wu et al 2012;Yang et al 2011).…”

application, large number of missing gaps was shown on the west of the TP, where it is considered that the retrieval algorithms are largely affected by the permafrost covered in this region, leaving the ESA soil moisture product for further improvement. In application, the ESA soil moisture product was used to study the response of surface soil moisture to climate change on the TP. With the rapid warming and the overall wetting of the TP, soil moisture increases on the central of the TP with the increase of precipitation, and decreases in the southeast TP with the precipitation deduction. However, it decreases in the west TP, where it was probably influenced by both the insignificant precipitation changes and the significant increase of evaporation.Keywords Hydrological consistency · ESA soil moisture product · Soil moisture · Precipitation · Trends · Tibetan Plateau Abstract As the first purely multi-decadal satellitebased soil moisture product that spans over 35 years (from November 1978 to December 2013) on a daily basis designed for climate application, the applicability of the European Space Agency (ESA) soil moisture product, including the hydrological consistency between the product and the observed precipitation and the product continuity on the Tibetan Plateau (TP) were investigated. The results show that there is significant degree between the ESA soil moisture product and the observed precipitation. The positive anomaly of the ESA soil moisture product can reflect the occurrences of precipitation, but the precipitation may not definitely lead to soil moisture anomaly, which largely depends on the precipitation amounts.

“…The internal dynamics of the atmosphere cannot last for extended periods. The persistent atmospheric heating anomaly over TP could be driven by the sea surface temperature anomalies (Hu and Duan, ; Ma et al ., ). Therefore, we also calculated the correlation and lag‐correlation between the SST anomalies and the sensible heat anomalies.…”

The influence of the spring sensible heat flux (SHF) over the Tibetan Plateau (TP) on the Asian summer monsoon rainfall (ASMR) has been widely investigated. Previous efforts have mainly used the SHF at meteorological stations located over the central and eastern TP. The relationship between the SHF over the entire TP and the ASMR over a time period of two decades is poorly known. Based on observational and reanalysis datasets, we analysed the impact of SHF anomalies on the ASMR from 1984 to 2007. Lag correlation analysis showed that the May SHF and atmospheric heat source (AHS) anomalies over the TP can persist until June and June–July, respectively. Partial correlation analysis, which removed the effects of the El Niño Southern Oscillation (ENSO) and North Atlantic Oscillation (NAO), was performed. Summer rainfall in northern China and northern India were positively correlated with the late spring SHF, while in western India and southern China, it was negatively correlated. The mechanism of these associations was demonstrated by composite analysis of winds and water vapour transport in the years of anomalously high and low SHF over the TP. The results highlight the importance of the changes in the surface and atmospheric conditions in late spring over the TP, which exert a significant influence on the ASMR through sensible heat anomalies.
