Regional average anomaly time series of extreme high temperature warning indicators (left column) and spatial distribution of long-term trends (right column) observed in China from 1961 to 2022

Caption

This figure illustrates the changes in TX40d (number of days with temperatures exceeding 40°C), TX40l (length of the season with temperatures exceeding 40°C), and TXx (intensity of high temperatures) over China. It demonstrates that TX40d is increasing, TX40l is extending, and TXx is strengthening, especially in 2022, the increase of these indicators has broken through historical extremes.
