Water Requirements for Growing Food

 

Did you know it takes much more water to maintain livestock than growing fruits and vegetables?  Click here to read the entire The New York Times article “Meat Makes the Planet Thirsty” on the water requirements (water footprint) for growing crops verses the requirements for the maintenance of livestock.  Something to consider regarding water conservation.

South Florida Winter Season Outlook 2013 – 2014

Beach_Image100

 

Rainy Season Summary:

 

  • Rainy season (May 18 – October 10) was wetter than normal across most of south Florida although there was a lack of large scale tropical systems affecting the area
  • Rainfall averaged 40 – 50 inches with some areas exceeding 50 inches
  • Most of the rainfall was induced by typical sea breeze interaction/convergence and a predominate moist southeast wind flow
  • The average dry season rainfall is 12 – 15 inches over the western and interior areas to 15 – 21 inches over eastern areas.

 

Climate factors affecting Dry/Winter Season:

 

Enso Phase

 

  • El Nino (Warm Phase) – Usually associated with cooler and wetter conditions and increased chance for severe weather as storm tracks tend to be further south
  • La Nina (Cold Phase) – Usually associated with drier and milder/warmer conditions. But there can be cold episodes
  • Neutral – Currently in neutral phase making predictability low confidence

 

PDO (Pacific Decadal Oscillation) – relates to areas of the north Pacific Ocean where it is cooler and warmer.  In the positive phase, the western Pacific is cooler and the eastern Pacific is warmer and in the negative phase it is opposite.  These are multiple decade trends (usually 20 – 30 years)  Currently it is in negative phase and is often associated with drier than normal winter and spring months.
There are other smaller scale occurrences that may have some influences including NAO (North Atlantic Oscillation), AO (Arctic Oscillation) and the PNA (Pacific/North American) to name some of them.  For further readings on these global patterns, click here.

 

 

Temperature Outlook:

 

  • Average winter temperature over interior and western portion is 64 – 66 degrees and 67 – 69 degrees over eastern areas
  • Near to slightly warmer than normal temperatures
  • Freeze episodes occur yearly to various degrees ranging from light/minor to severe causing widespread crop damage
  • This winter is about average to see a moderate to severe freeze
  • Freezes typically occur in December and January, but can occur well into February
  • Freezes are most likely over the interior areas of southwest Florida and around Lake Okeechobee.  Possibility of freezes decrease significantly closer to the metro and coastal areas.
  • This winter is about average to see a moderate to severe freeze

 

 

Precipitation Outlook:

 

  • Based on the climate factors mentioned above, drier than normal conditions are expected (however, as indicated, due to Neutral ENSO conditions, this is low confidence prediction)
  • May lead to less severe weather
  • May lead to increased fire danger due to vegetation growth during the rainy season into the early dry season
