Fig. 1. Locations of the mountain stream water temperature monitoring sites.
Fig. 2. Box plots of monthly distributions of daily mean air and mountain stream water temperatures of the monitoring sites during observed period. The upper and lower hinges correspond to the first and third quartiles(the 25th and 75th percentiles), respectively. The whiskers extend from the hinges to the highest and lowest values that are within 1.5 (the inter-quartile range). Values beyond the end of the whiskers are outliers and plotted as points. Dashed line represents mean value of total daily mean air and mountain stream water temperatures of the monitoring sites during observed period.
