What does this mean for Peaches? • Do different ENSO patterns impact the date at which critical chill hours are reached (number of hours below 45 F)? • Is there an increased risk of freeze damage associated with different ENSO patterns?
Conclusions • There has been no trend in the date at which critical chill hours are reached • There is no trend in the date of the last 28F in the spring
ENSO Conclusions • The Winter Climate Pattern Determines When Critical Chill Hours are Reached • Chill Hours are Reached Earlier during Neutral and El Nino Climate Pattern Winters • No relationship between ENSO and Date of the Last 28F • Increased Risk of Late Freeze Damage during Neutral and El Nino Climate Pattern Winters
