Analysis on the Extreme Heat Wave over China around Yangtze River Region in the Summer of 2013 and Its Main Contributing Factors

Figure 1

The distribution of the highest value of DMT anomalies (°C) running-averaging (a) daily, (b) weekly, (c) biweekly, (d) monthly, and (e) seasonally and in the anomaly of the total HDs (days) in 2013 summer in China (f). The shaded areas denote the highest value of DMT anomaly, and the lines denote the 90th percentile threshold of DMT anomaly for 1961–2013 for the corresponding time scales. The rectangle (26.4°N–34.2°N, 105°E–122°E) in Figure 1(f) indicates region A. “ChQ,” “ShH,” and “ZhJ” in (f) indicate the geographical location of Chongqing, Shanghai, and Zhejiang province.
