jpbart Posted May 22 Share Posted May 22 I understand what ONI in, and SOI, but what is RONI? I tried searching for but to no avail. Can somebody explain this please? Link to comment Share on other sites More sharing options...
weatherwiz Posted May 22 Share Posted May 22 There are a few papers on this out there. Essentially, the RONI is the conventional Nino 3.4 index minus the SSTA averaged across the whole tropics to remove the global warming signal. 1 Link to comment Share on other sites More sharing options...

Ed, snow and hurricane fan Posted May 26 Share Posted May 26 Wouldn't RONI minimize the upcoming cool ENSO because of the warming Atlantic. I know that is the opposite of what it is supposed to do, I can see how it works with a warm ENSO, but not a cool one. Link to comment Share on other sites More sharing options...

No, it is the opposite because RONI looks at the contrast better with the surrounding extra warm waters that were caused by GW. With this last El Nino, RONI peak was only high end moderate vs ONI peak of borderline strong/super-strong. So, RONI was ~0.5C cooler than ONI. For the upcoming La Nina, there's a good chance for a similar relationship where ONI dips only to, say, -1.0 or -1.4 while RONI dips to, say, -1.5 or -1.8 meaning RONI once again cooler. 1 Link to comment Share on other sites More sharing options...

Typhoon Tip Posted June 5 Share Posted June 5 Ah ... not sure y'all got that quite right. RONI is actually a colloquialism for Pepperoni, a variety of spicy salami-style processed food made from an amalgam of cured pork and beef, seasoned with salt, paprika, chili flakes or cayenne pepper, fennel seed and garlic. The term was long ago formulated amid Americana for its delectable inclusion and is therefore most useful in that culinary application and recognition. So tired of misnomers 1 1 1 Link to comment Share on other sites More sharing options...
