Coming ENSO (El Nino) = build raingardens & planning 4 drought

I was graced by a call from my wonderful neighbor and Santa Fe native, Zelie Pollon, who is now on news staff duties at KSFR and doing a great job.  She asked me about River Source restoration, water harvesting, and planning work in the City and County of Santa Fe and I suggested we talk about the strenghening ENSO (El Nino Southern Oscillation) that is now about 60% positive and may go 80% positive this fall.  You’ll find a good website here shows the current ENSO projection and has animated graphs and shows comparisons of about a dozen model projections and all are leading to a strengthening El Nino.

El Nino/La Nina describes an ocean/atmosphere dynamic in the southern Pacific ocean between Darwin, Australia and the coast of Peru/Ecuador (a macroscopic dynamic) that affects the global climate strong confidence going forward about 3-6 months.  This makes tracking ENSO, as a the indicator is often called, very valuable for predicting and then planning for different moisture regimes in the coming 3-6 months.

Since that day about 12 days ago we’ve received about 1.1 inches of rain from a strong monsoon season !  Yeah!  But we need to plan to harvest water around our open space trees, create rain gardens, spread seeds and perhaps plant in well watered areas as this may a good chance to revegetate parched areas.  The current ENSO means we have a much better chance of reforestation, for instance, than we did over the past 3 years.

So what does 60-80% positive forecast for an El Nino mean?  First download the weekly forecast in PDF format and understand it as well as you can.   Then go to page 25 and see a comparison of the models on the SST departure predictions over the coming 1-10 months  as far out as February-March-April 2015.   This gives you an idea how to predict rainfall so you can plan for the future!
