Day‐to‐Day Temperature Variability in China During Last 60 Years Relative to Arctic Oscillation
Abstract Day‐to‐day (DTD) temperature variability is an important characteristic of air temperature and is closely related to the economy, ecology, and human health. According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, the air temperature has increased particula...

Abstract Day‐to‐day (DTD) temperature variability is an important characteristic of air temperature and is closely related to the economy, ecology, and human health. According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, the air temperature has increased particularly during the most recent decades. However, the temporal and spatial variations of DTD temperature variability have not been fully addressed. In this study, the DTD temperature variability is calculated using observed air temperature from meteorological stations in China. The regional and seasonal performances are evaluated among different climate regions and half‐year periods. In addition, the relationship between DTD temperature variability and the Arctic Oscillation (AO) is evaluated. The national mean DTD temperature variability in 1961–2020 during the warming (cooling) half‐year was 1.8°C (1.5°C), with minimum (maximum) values occurring in the southwestern (northeastern) regions of mainland China.
