From: Skillful prediction of hot temperature extremes over the source region of ancient Silk Road
Location of stations (black dots) used in the study, analysis domain (the black box), and annual precipitation averaged over 1981–2010 from CRU TS 4.00. The purple dot denotes the location of Chang’an (Today’s Xi’an in Shaanxi province of China), the capital of Han Dynasty of China. Chang’an is the starting point of ancient Silk Road. The CRU precipitation data were obtained from University of East Anglia Climatic Research Unit (http://catalogue.ceda.ac.uk/). This map was generated with NCAR Command Language (NCL) version 6.3.0 (Boulder, Colorado: UCAR/NCAR/CISL/TDD. http://dx.doi.org/10.5065/D6WD3XH5).
