  2. Arizona’s Climate • Bimodal Precipitation Pattern • Wide Diurnal Temperature Fluctuations • Elevation Differences Cause Variability • Highly Variable Summer Precipitation • Periodic Drought • Monsoon Most Dependable in Southeastern Portion of the State

  3. Freeze Probabilities - Prescott Spring Freeze Probabilities (32.5 degrees F) Fall Freeze Probabilities (32.5 degrees F) Average Growing Season = 140 days

  4. Freeze Probabilities - Cottonwood Spring Freeze Probabilities (32.5 degrees F) Fall Freeze Probabilities (32.5 degrees F) Average Growing Season = 194 days

  5. El Nino and La Nina • Related to temperature and current in the equatorial Pacific Ocean • El Nino increases the probability of winter precipitation for Arizona • La Nina almost always forecasts low winter precipitation for Arizona
