Note: Numbers with + and ++ signs are significant at 5% and 1%, respectively. Q, P, T, RH, and Snow are streamflow, precipitation, temperature, relative humidity, and sum of snowfall in year, respectively. K is change point calculated, and Change point is time of rapid change in series. Mean of 1st period and Mean of 2nd period is mean of variable in the first and second period, respectively.
