While the number of wet days is onlyslightly changed, the average drought duration decreases in the future climates from 13 days to 9 or 10 days.200180160140120days/yr 10080604020060 61 99Scenario ID #Wet daysDry daysFigure 5-9: Annual average number of wet and dry days for SDSM future climates compared to the currentclimate.This study also compared climates in terms of the number of hot days (i.e., > 30 o C) and cold days (< 0 o C) asillustrated in Figure 5-10. In all cases, the number of hot days is expected to increase substantially with increasesranging from 7 to 29 days above the current level of 5 days per year. Conversely, the number of cold days isexpected to decrease by 15 to 41 days per year.200180160140120days/yr 1008060402009 16 30 33 38 40 48 53 54 58 59 60 61 99Scenario ID #> 30 deg
