El Niño and La Niña multi-year events more common?

[weatherfan2012]

What interesting is sort term El nino has a warming effect long term El nino system has a cooling tendency.Same with La nina sort term it has a leveling off cooling effect but long term in a La nina system it tends to go along with warming cycles climate as oppose to cooling cycles.

Some improvement in the upper Mississippi valley. Drought in SE New Mexico and SW Mississippi intensifies. Some severe drought shows up in Oregon.

 

Not worried about drought here anymore. Our summers have been insane the past 3 years, but this is our 3rd wet winter in a row with decent snow pack. An extreme blessing in a strong Nino winter.

Gulf coast looking very dry.  
Doesn’t bode well for crops.  

…..Outlook for Texas?

[AquariusRadar]

The weekly drought map shows no dramatic changes. But more and more, little by little, the upper regions of our biggest rivers are showing  very dry or some drought. The Mississippi, Snake, Missouri, Colorado, and Rio Grande are all, at least, very dry. Your'e right Andie. Not looking good for a hot summer ahead. The Ohio, Tennessee, and other larger rivers of the Southeast are currently free of dry conditions. But these rivers lack a snow pack source and will be subject to rapid drying as the summer heat comes on. The Sacramento and west coast rivers are ok..with more moisture expected this spring and backed up by good snowpack.

We haven’t received much rain through the winter.  
It really needs to rain.

this was a strange El nino Alot of research I think will be look at it but my bet is the pacific had a play with a over all La nina background state which may have interruped the normal El nino tendaceys.

-PDO messed it up

Well, …it sucked.

Drought map unchanged this week.

 

[AquariusRadar]

No major change in the drought map. A small area of extreme drought in Western Montana has cleared.

[AquariusRadar]

The tiny areas of extreme drought in upper Idaho and Montana have returned. The extreme area in Iowa has decreased. The drought areas of the Kansas and Oklahoma (very dry) and desert Southwest are expanding to merge in the Texas panhandle. If that trend continues, there will be a continuous line of drought that extends from the boot heel of New Mexico to the upper Great Lakes.

Multi-year la nina events are more common, but not multi-year el nino events. It comes down to the fact that it's easier to sustain a la nina event than an el nino. It's very rare to have consecutive el nino years. Before 2014-15 and 2015-16 (and possibly 2018-19 and 2019-20), the last time we had back-to-back el nino years was 1986-87 and 1987-88.

[AquariusRadar]

Not much change in the drought conditions. A little less of the intense drought in Iowa but Iowa and Kansas are mostly in some level of drought. The southwest drought continues.
