No Evidence that Atlantic and Pacific Oscillations Exist

 

Atlantic and Pacific Oscillations Lost in the Noise,
Penn State, January 3, 2020.

MAIN POINTS

PDO Does Not Exist
"The Atlantic Multidecadal Oscillation (AMO) and the Pacific Decadal Oscillation (PDO) do not appear to exist..."

Static
"Using both observational data and climate model simulations, the researchers showed that there was no consistent evidence for decadal or longer-term internal oscillatory signals that could be differentiated from climatic noise -- random year to year variation."

No PDO Evidence
"Given the current sophistication of climate models as seen in their ability to capture the El Niño/Southern Oscillation, we would expect to see consistent evidence for oscillations across a suite of climate models... We found no such evidence."

Nada-Ziltch
"...we found no other signals, no Pacific or Atlantic climate variability on decadal or longer timescales that could be characterized as a true oscillation. Such variability was essentially indistinguishable from random noise."

Warming Waters Making Pacific Decadal Oscillation Less Predictable

Seasonal Forecasts Challenged by Pacific Ocean Warming,
CSIRO Australia, December 17, 2019.

MAIN POINTS

Less Predictable
"The research found that the PDO would become less predictable as the planet warms, because warming conditions result in a significantly shortened PDO lifespan."

PDO Definition from NOAA
PDO Pacific Decadal Oscillation
Currently at a Negative Value
"The Pacific Decadal Oscillation (PDO) is often described as a long-lived El Niño-like pattern of Pacific climate variability."-NOAA.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
