A gridded daily observation dataset over China region and comparison with the other datasets
TLDR
In this paper, a new gridded daily dataset with the resolution of 0.25°latitude by 0.75°longitude, CN05.1, is constructed for the purpose of high resolution climate model validation over China region.Abstract:
A new gridded daily dataset with the resolution of 0.25°latitude by 0.25°longitude,CN05.1,is constructed for the purpose of high resolution climate model validation over China region.The dataset is based on the interpolation from over 2400observing stations in China,includes 4variables : daily mean,minimum and maximum temperature,daily precipitation.The " anomaly approach " is applied in this interpolation.The climatology is first interpolated by thinplate smoothing splines and then a gridded daily anomaly derived from angular distance weighting method is added to climatology to obtain the final dataset.Intercomparison of the dataset with other three daily datasets,CN05for temperature,and EA05and APHRO for precipitation is conducted.The analysis period is from 1961to 2005.For multi-annual mean temperature variables,results show small differences over eastern China with dense observation stations,but larger differences(warmer) over western China with less stations between CN05.1and CN05.The temperature extremes are measured by TX3D(mean of the 3greatest maximum temperatures in a year) and TN3D(mean of the 3lowest minimum temperatures).CN05.1in general shows a warmer TX3Dover China,while a lower TN3Din the east and greater TN3Din the west are found compared to CN05.A greater value of annual mean precipitation compared to EA05and APHRO,especially to the latter,is found in CN05.1.For precipitation extreme of R3D(mean of the 3largest precipitations in a year),CN05.1presents lower value of it in western China compared to EA05.read more

Surface air temperature changes over the Tibetan Plateau: Historical evaluation and future projection based on CMIP6 models
TL;DR: In this paper , the authors used 28 global climate models to assess model performance regarding surface air temperature over the Tibetan Plateau from 1961 to 2014, reported spatiotemporal variability in surface air temperatures in the future under four scenarios (SSP1-2.6, SSP2-4.5 and SSP5-8.5), and further quantified the timing of warming levels (1.5, 2, and 3 °C) in the region.
Impact of Aerosol Radiative Effect on the Diurnal Cycle of Summer Precipitation Over North China: Distinct Results From Simulations With Parameterized Versus Explicit Convection
TL;DR: In this article , the influence of aerosol radiative effects and model convection schemes on the diurnal cycle of precipitation (DCP) in North China was investigated. And the authors found that the EC experiments show delayed but more realistic DCPs compared with the PC experiments.

Inter-Comparison of Diverse Heatwave Definitions in the Analysis of Spatiotemporally Contiguous Heatwave Events over China
TL;DR: Wang et al. as mentioned in this paper investigated the influence of selected threshold methods (the absolute threshold method (ABS), quantile-based method (QTL), and moving quantilebased method(QTLmov)) and selected variables (heat index (HI), air temperature (Tair)) on the change patterns of spatiotemporally contiguous heatwave (STHW) characteristics over China from 1961-2017.
