“…The southern boundary of the temperate climate zone (D type) is projected to shrink northward due to the expansion of subtropical climate (C). These are supported by the previous studies, assessed under the SRES A1B scenario (Shi et al, 2012;Yun et al, 2012) and other RCP scenarios (Lee et al, 2017) at the end of the 21st century. These changes were accompanied by increases of both CDD (Figure 2b) and extreme precipitation intensity (Figures 2c and 2d), which increased the hydroclimatic stress (HYINT) (Figure 2e).…”

“…In order to understand the impact of the target GWL on the environment of EA, comprehensive analyses that consider the changes of climatic variables are needed. A few studies have assessed Köppen-related climate-type changes over EA, merely focused on a relatively small area in the CORDEX-EA2 domain (i.e., Shi et al, 2012, andChan et al, 2016, for China;Yun et al, 2012, andLee et al, 2017, for S. Korea;Talchabhadel & Karki, 2019, for Nepal) using different emission scenarios, horizontal resolutions, and analysis periods. Since this metric has a threshold that considers plant sensitivity, it can be used as a baseline estimation of feasible biomes and ecosystem changes.…”

“…Therefore, the Köppen scheme is used widely for climate change impact research with Special Report on Emission Scenarios (SRES; e.g., Gallardo et al, 2013;De Castro et al, 2007;Gao & Giorgi, 2008;Feng et al, 2012) and Representative Concentration Pathway (RCP) scenarios (e.g., Rajaud & de Noblet-Ducoudré, 2017;Chan & Wu, 2015;Zeroual et al, 2019;Mahlstein et al, 2013). A few studies have assessed Köppen-related climate-type changes over EA, merely focused on a relatively small area in the CORDEX-EA2 domain (i.e., Shi et al, 2012, andChan et al, 2016, for China;Yun et al, 2012, andLee et al, 2017, for S. Korea;Talchabhadel & Karki, 2019, for Nepal) using different emission scenarios, horizontal resolutions, and analysis periods. Since the differences in the projection domain (Bhaskaran et al, 2012;Leduc & Laprise, 2009;Žagar et al, 2013), horizontal resolution (Shi et al, 2018;Evans & McCabe, 2013), or model sensitivity to GHG forcing Sylla, Pal, et al, 2018) could be the source of the uncertainty in regional climate projections, it is important to coordinate experiments and assess the future projection from the same baseline (e.g., PI level).…”

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.

“…In general, the present distribution of Köppen climate types over China simulated by the TraCE-21ka is comparable to the observational pattern presented by Peel et al (2007), although local small differences exist. In addition, the simulated modern Köppen climate zones are also consistent with those derived from other studies that are based on the current observational gridded datasets (Chan et al, 2016;Cheng et al, 2015;Kottek et al, 2006;Peel et al, 2007;Shi et al, 2012).…”

The regions that encompass similar climates can be regarded as one climate zone. There are a variety of methods to classify climate regions, such as cluster analysis (Zhang et al., 2017; Zhang & Yan, 2014) and threshold values of certain climate variables (Feddema, 2005; He et al., 2019). The most frequently used scheme is the Köppen climate classification scheme, which was the first quantitative classification of world climates proposed by Wladimir Köppen in 1900 (Köppen, 1900; Kottek et al., 2006) along with subsequent modified versions (Köppen, 1936; Trewartha & Horn, 1980). The Köppen climate classification improves the efficiency of descriptions by integrating various climate variables into a single map (Belda et al., 2014; Guetter & Kutzbach, 1990). The release of long-term observational data has made it possible to draw a digital Köppen climate world map (Kottek et al., 2006; Peel et al., 2007) and has enabled validation of the ability of general circulation models (GCMs) to reproduce the modern climatological distributions of Köppen climate types (

ABSTRACT:We considered shifts in the Köppen climate zones and the corresponding impact on the crop yields in Serbia by comparing (1) the results of downscaling with the ECMWF Hamburg Atmospheric Model 5 (ECHAM5) and regional Eta Belgrade University (EBU)-Princeton Ocean Model (POM) model for the A1B and A2 scenarios over 2001-2030 and 2071-2100 and (2) the present climate simulations for the period 1961−1990. We analyzed the EBU-POM regional climate model complexity by calculating the corresponding metrics. The yields of winter wheat, maize and soybeans were evaluated with the Decision Support System for Agrotechnology Transfer (DSSAT) model.In the future, the Köppen climate zones of Serbia will shift in coverage percentage and altitude from the present climate simulations toward warmer and drier climate zones. The calculated climate indices feature changes in the following parameters: increases in the mean annual temperature, growing season temperature, number of growing degree days (higher than 5 ∘ C) and the frequency of tropical days; and decreases in the mean annual precipitation, growing season precipitation and frequency of frost days. Yields of crops (winter wheat, maize and soybeans) will increase on average under both scenarios, with the exception of maize in non-irrigated conditions and under the A2 scenario.
