The city has a continental, monsoon-influenced semi-arid climate (Köppen BSk), characterised by hot, humid summers due to the East Asian monsoon, and generally cold, windy, very dry winters that reflect the influence of the vast Siberian anticyclone. Spring can bear witness to sandstorms blowing in from the Mongolian steppe, accompanied by rapidly warming, but generally dry, conditions. Autumn is similar to spring in temperature and lack of rainfall. January averages −2.3 °C (27.9 °F), while July averages 26.8 °C (80.2 °F); the annual mean is 13.4 °C (56.1 °F). More than half of the annual rainfall occurs in July and August alone
