Abstract: | A 30-year meteorological station and reanalysis datasets revealed that the frequency and intensity of hot extremes have increased dramatically around Mongolia since the late 1990s. Many recent heat waves (HWs) were triggered by atmospheric forcing with a mid-tropospheric ridge pattern which appears frequently around Mongolia in 2000s. An observational data analysis for each HW event indicates that the rate of temperature increase at the beginning stage of HW is sensitive to the soil moisture condition. Therefore, it is suggested that the recent drier soil conditions played a role in enhancing the frequency and intensity of HWs and localization around Mongolia. |
