TT-SEA Posted January 31, 2018 Report Share Posted January 31, 2018 Well, we watched the first two episodes this evening. Twisted but very good. I am in now into season 3... my wife is way behind since I usually stay up later. I love the realism... actually filmed in Chicago. That is a real neighborhood and that is the real 'L' train roaring by with actual passengers. Even the seasons and the weather follow along much nicer than most shows. I know you pay close attention to that stuff too. And the characters are great... always enjoy watching Macy. But its starting to feel more like an all too neatly packaged formula TV series in the third season... introduce a challenging situation and it will get crazy and then all wrap up perfectly in one hour. That might work when you are watching one episode a week and 12 episodes a year... but it becomes more noticeable and annoying when you are binge watching. Still enjoying it... and all of the seasons scored very high on Rotten Tomatoes. Some seasons have a score of 100%.

Washington as of now is above normal, Idaho about normal, though of course Oregon is not doing well. So I don't agree that it has been that bad the last few years. In 2015 of course we had the terrible year with the warm blob, but since then things have picked up, even though we had the big El Nino two winters ago. 1 Quote Link to comment Share on other sites More sharing options...

A return to ENSO-neutral conditions before early 2018 is less likely, while the emergence of El Niño before the second quarter of 2018 appears very remote. 1 Quote Link to comment Share on other sites More sharing options...

Phil Posted January 31, 2018 Report Share Posted January 31, 2018 It wouldn’t shock me if we enter “neutral” conditions as soon as M/A/M. With two downwelling OKWs now present, we’ll probably see another niño “head fake”, but the QBO should put the breaks on any attempt at a real niño, similar to what happened in 2012. I think ENSO neutral is a safe bet for most of 2018 and the winter of 2018/19, at this point in time. FWIW, I still like 2019/20 for the next El Niño, followed by a multi-year period of moderate to strong La Niñas in the early 2020s, as would favored by the solar/IPWP cycle and other longer period equator/pole harmonics. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

If it’s a prolonged minimum, there’s a slight chance that we could see a two year El Niño (2019/20 and 2020/21) before the multi-year La Niña afterwards, but that looks less likely right now IMO.

Phil Posted January 31, 2018 Report Share Posted January 31, 2018 FWIW, the years that feature these big jumps in the intensity of WPAC forcing (vs the previous year) tend to precede Niños. See 1997, 2015, 1994, etc on the above image. However, none of those years were in the process of descending into -QBO, which works against El Niño development. The two exceptions are 2001 and 2011..and both avoided El Niño thanks to the -QBO..though they’re both solar maximum years, which blurs the picture. Unusual stuff right now, regardless.

Phil Posted January 31, 2018 Report Share Posted January 31, 2018 By 2020 we’ll be hearing about multi year La Nina’s in the mid 2020s.No, you won’t. I’ve had this prediction for awhile. Expect another Niño “head fake” this spring before a retraction to ENSO neutral for winter 2018/19, followed by the climatological solar min/El Niño response in 2019/20, then a very amplified multiyear La Niña spanning the early 2020s. At least one winter in the early 2020s will feature a strong La Niña. The climate system has been undergoing a significant transition since 2012/13. Except for 2015/16, the ENSO has been essentially dormant since then. Recent years with largely dormant ENSO include 2012/13, 2013/14, 2014/15, and 2016/17. We can probably add 2018/19, as well. Quite the stretch. The El Niño of 2019/20 wil mark the return of a more amplified ENSO phase, IMO. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted January 31, 2018 Report Share Posted January 31, 2018 If you’ve read the literature on tropical climate, you know that “slowing down = speeding up”. In other words, when we get these multi-year stretches with stagnant tropical forcing/dormant ENSO, we observe large scale reorganization(s) of the climate during or after their termination. A dormant ENSO represents a “change in direction” for the system, like when you hit the breaks before making a turn in a vehicle. Usually, the more prolonged the dormant stretch, the more significant the upcoming regime change.
