The temperature thresholds and timings of the 24 climatic Solar Terms in China are determined from a homogenized dataset of
the surface air temperature recorded at 549 meteorological stations for the period 1960–2008 employing the ensemble empirical
mode decomposition method. Changes in the mean temperature and timing of the climatic solar terms are illustrated. The results
show that in terms of the mean situation over China, the number of cold days such as those of Slight Cold and Great Cold has
