2. 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?

13. 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

14. 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
