Con­di­tions in the Pacific Ocean seem to be shift­ing toward the return of the La Niña weather phe­nom­e­non, the lesser-​known rel­a­tive of the El Niño weather anom­aly, accord­ing to fore­cast­ers at the Jet Propul­sion Lab­o­ra­tory in Pasadena. What does that mean for SoCal gar­den­ers? Experts say a lot less rain in an area already plagued by drought conditions.

Right now, I’d say the dice seem loaded for an immi­nent La Niña,” Bill Patzert, a long-​range fore­caster at the Jet Propul­sion Lab­o­ra­tory in Pasadena told the San Diego Tri­bune. “It’s not a good sign. La Niña is what I call the diva of drought for the Southwest.”

The U.S. Cli­mate Pre­dic­tion Cen­ter said a large num­ber of com­puter mod­els indi­cates “the onset of La Niña conditions.”

La Niña is char­ac­ter­ized by unusu­ally cold ocean tem­per­a­tures in the Equa­to­r­ial Pacific, com­pared to El Niño, which is char­ac­ter­ized by unusu­ally warm ocean temperatures.

In the past sev­eral weeks, ocean tem­per­a­tures have dropped significantly. And from Bill Patzert, “For those who think in terms of “nor­mal” rain­fall for Los Ange­les: “Nor­mal is a cycle on a wash­ing machine.”

The pre­dic­tion map below is from the National Weather Ser­vice site. The first map is for Sep-​Oct-​Nov/​2010 and the last map is for Aug-​Sept-​Oct/​2011. The white areas are nor­mal rain­fall, the green above nor­mal, and the brown areas are below nor­mal. I’m tear­ing out my lawn as soon as I can afford it.
