To examine the temperature changes since the beginning of the 21st century, we selected 2000–2003 as the base period and found that the recent temperature change (2016–2019) has significantly changed compared with the base period. The figure shows the distribution of the maximum temperature, average temperature, and minimum temperature in the two periods within the season.
