Making a bet about a wet or dry winter this year? Don’t look for El Nino or La Nina to give you an edge. It’s looking like La Nada so far.
San Luis Reservoir has been low this year due to drought and pumping restrictions in the delta;
If you don’t know, El Nino and La Nina are all about the shallow water temperature in the Pacific Ocean around the equator. Nino means warmer than usual — an indication California might have a wet winter. Nina means cooler — a hint that it might be dry.
After two arid winters years and the long, dry summer of 2013, I hear from a lot farmers, city leaders and business folk who want some idea about the winter to come.
But the Pacific isn’t giving anyone a clue this year. Scientists say it is neither warm nor cool. Which means it’s just a coin flip so far, unless things change soon.
I like to follow Jan Null’s web site about the phenomenon. Null is a private meteorologist in the Bay Area, and you can learn a lot from his page.
Meanwhile, all bets are off when the ocean is in neutral. Will it stay in neutral? NOAA says it looks like neutral conditions will remain for the 2013-2014 winter.
“I expect another extended dry (temperatures cool to near normal) pattern to set in for the next one to two weeks,” meteorologist Paul Iniguez in the NWS Hanford office.
He said his forecast is in line with the NOAA Climate Prediction Center, which says odds favor a drier than average spring. Iniguez said precipitation for California is below normal.
For those who follow this stuff, check out NOAA’s El Nino-La Nina discussion. El Nino is the warm water phenomenon in the Pacific Ocean, sometimes meaning California will be wet. La Nina, corresponding to cooler water, can mean drier, cooler winters here.
Unfortunately, the Pacific is neither Nino, nor Nina this year. It’s tougher to handicap the wet season when neither is present in the ocean.
