China has experienced rapid urbanization and dramatic economic growth since its reform process started in late 1978. In this article, we present evidence for a significant effect on climate based analysis of impacts land-use changes surface temperature southeast China, where occurred. Our estimated warming mean 0.05°C per decade attributable to is much larger than previous estimates other periods locations. The spatial pattern magnitude our estimate are consistent with those characterized by...
This study first homogenizes time series of daily maximum and minimum temperatures recorded at 825 stations in China over the period from 1951 to 2010, using both metadata penalized t test with first‐order autocorrelation being accounted for detect change points quantile‐matching algorithm adjust data diminish discontinuities. Station relocation was found be main cause discontinuities, followed by station automation. The effects discontinuities on estimation long‐term trends annual mean...
Global surface temperature trends, based on land and marine data, show warming of about 0.8°C over the last 100 years. This rate is sometimes questioned because existence well‐known Urban Heat Islands (UHIs). We examples UHIs at London Vienna, where city center sites are warmer than surrounding rural locations. Both these however do not contribute to trends 20th century influences cities temperatures have changed this time. In main part paper, for China, we compare a new homogenized station...
Abstract The accuracy of any gridded climatic data sets is as important their availability for regional climate and ecological studies. In this study, the estimated precipitation in central Asia from three recently developed reanalysis sets, Modern‐Era Retrospective Analysis Research Applications (MERRA), ECMWF Interim Re‐Analysis (ERA‐Interim), Climate Forecast System Reanalysis (CFSR), evaluated through comparisons with observations 399 stations during 1979–2010. An interpolated set...
The oceanic and atmospheric conditions the related climate impacts of 2015/16 ENSO cycle were analyzed, based on latest global observational data, especially that China. results show this strong El Niño event fully established in spring 2015 has been rapidly developing into one three strongest episodes recorded history. Meanwhile, it is also expected to be longest recorded, attributable stable maintenance abnormally warm equatorial Pacific Ocean since 2014. Owing event, along with warming...
Abstract Based on the homogenized data set, we analyze changes in mean temperature and some extreme indices over China since 1961 especially during recent warming hiatus period (1998–2012) a global average context. The result shows that decrease of annual maximum has contributed most to decreases overall diurnal range (DTR) period. In parts except southwest, summer ( T xS ) largest increase, while winter minimum nW indicates slight cooling trends. These have augmented seasonal cycle...
Abstract Heavy PM 2.5 (particulate matter with aerodynamic diameter equal to or less than μm) pollution and urban heat island (UHI) pose increasing threats human health living environment in populated cities. However, how affects the UHI intensity (UHII) has not been fully understood. The impacts of on wintertime UHII Beijing‐Tianjin‐Hebei megalopolis China are explored during 2013–2017. results show that at time daily maximum/minimum temperature (UHII max /UHII min ) exhibits a...
The accuracies of gridded precipitation data sets are important for regional climate studies and hydrological models. In this study, the performances Global Precipitation Climatology Centre (GPCC) V7, Climatic Research Unit (CRU) TS 3.22 Willmott Matsuura (WM) were examined over central Asia by comparing them against observed records (OBS) from 586 meteorological stations during 1901–2010. results show that all three underestimated at annual monthly scales, especially in mountainous areas....
Abstract The extent to which an urbanization effect has contributed climate warming is under debate in China. Some previous studies have shown that the urban heat island (UHI) contribution national was substantial (10%–40%). However, by considering spatial scale of effects, this study indicates UHI negligible (less than 1%). Urban areas constitute only 0.7% whole According proportions and rural used study, weighted temperature averages reduced estimated total trend also effects. Conversely,...
Abstract The United Nations has reported that 55% of the global population resides in urban areas, and 68% is expected to be dwellers by 2050. Urbanization critical implications for land cover. Relevant literature provided evidence attributing climatic effects expansion; however, few studies have investigated effect on public health pollutant sensitivity emissions. This study aimed characterize urbanization‐induced changes regional climate ozone (O 3 ), evaluate nitrogen oxide (NO x )...
We assess the correspondence of reanalysis air temperatures from ERA‐40, NCEP‐1, and NCEP‐2 with homogenized observational data China for 1958–2001 1979–2001. Results indicate that climatologies annual are lower than observations by −0.93°C, −2.78°C, −2.27°C, respectively. Large negative differences most western primarily contribute to this cool bias. Error analysis indicates internal coherence ERA‐40 is better NCEP‐1 or NCEP‐2. Although represent an improvement over biases relative still...
Abstract During 1977–1981 the Beijing (BJ) meteorological station was at a suburban location. In 1981 it moved to more urban location, but in 1997 subsequently back same The daily BJ temperature series, together with those from 18 nearby stations, form unique database for studying how site‐change and possible urbanisation influences affect climate changes local scale. site‐change‐induced biases were quantified, between 0.43 0.95 °C, based on comparisons multi‐year‐mean seasonal anomalies...
The China Homogenized Historical Temperature (CHHT) dataset (1951-2004) version 1.0 consists of monthly and daily surface observations from all national stations in mainland China. primary objective CHHT is to build a set homogenized observational climatic datasets reduce uncertainty the detection observed change variability. covers years 1951-2004 two formats that are grids with 2.5°×2.5° spatial resolution developed by using mean, minimum maximum temperatures total 731 weather distributed...
Abstract Observations are the foundation for understanding climate system. Yet, currently available land meteorological data highly fractured into various global, regional, and national holdings different variables time scales, from a variety of sources, in mixture formats. Added to this, many still inaccessible analysis usage. To meet modern scientific societal demands as well emerging needs such provision services, it is essential that we improve management curation land-based holdings. We...
Abstract Time series of global or regional average surface air temperature (SAT) are fundamental to climate change studies. A number studies have developed several national and SAT for China, but because the diversity meteorological observational sites, different quality control routines processing data, inconsistency statistical methods used, they differ in their long-term trends. This paper assesses similarities differences existing time annual China that based upon historical observations...
