Key to symbols

value of the index (over the period indicated to latest value)

 strongly positive (+1 std < x)
 weakly positive (+0.3 std < x < +1 std)
 neutral (-0.3 std < x < +0.3 std)
 weakly negative (-1 std < x < -0.3 std)
 strongly negative (x < -1 std)

x = value of the index over the period indicated to the latest value
std = series standard deviation over period of the climatology

tendency (rate of change over period indicated to latest value)

 strong positive tendency (+1 stdx < dx)
 weak positive tendency (+0.3 stdx < dx < +1 stdx)
 no change (-0.3 stdx < dx < +0.3 stdx)
 weak negative tendency (-1 stdx < dx < -0.3 stdx)
 strong negative tendency (dx < -1 stdx)

dx = slope of linear fit to values over the period of time indicated, ending at latest value of the index
stdx = standard deviation of dx over the period of the climatology
