TT-SEA Posted April 24, 2016 Report Share Posted April 24, 2016 To summarize the above^ What I reported is what actually happened. You are showing some vague low resolution map based on sparse data from 1889 and lumping 3 months together. Side note... July was very warm and dry by even our standards today. Total rain of 0.00 in Portland and only 4 days below 80. And 8 days in the 90s. July of 1889 would have been despised by the cold weather fans on here. Average high in July 1889 was 84... average last July was 86 and that was one hot month.

TT-SEA Posted April 24, 2016 Report Share Posted April 24, 2016 Like I said... I really think 1889 might be a good guide for 2016. Strong Nino transitioned to Nina by summer and was at the very end of solar cycle with very low solar activity... all just like 2016 it seems. Really the only year since the 1870s that matches those basic criteria. I also think 2016 will be warmer than 1889 because the climate has warmed in the last 127 years.

Dan the Weatherman Posted April 24, 2016 Report Share Posted April 24, 2016 I would give my next few paychecks to have a season play out like 1889-90. I wouldn't mind a repeat of 1889-90, either, as it was one of the wettest winters on record for Los Angeles, and the rainfall distribution had similarities to 2010-11, especially in the fall and early winter months. From looking at SOI (Southern Oscillation Index) data, both 1889-90 and 2010-11 had multiple months of SOI indices averaging in the +20's, the only two La Nina events that I know of that featured that consistently high of a SOI. 2010-11 brought nearly 20" of rain to Los Angeles and was a banner snow year for the Sierra, and was the last great year before this terrible drought pattern set in. This "super El Nino" year has brought barely half of the amount of rain to L.A. that 2010-11 did. Quote Link to comment Share on other sites More sharing options...

Looking at the MEI... the 1889 Nino was still strong in March/April but was completely gone by the May/June reading and was a moderate Nina by July/August. That is a very rapid transition.

What source are you using for MEI back in 1889? I don't know of any peer reviewed MEI dataset going back that far. The M/J/J trimonthly ONI was clearly positive, and the MEI lags the ONI to a slight degree. So something is wrong with this picture. The ONI didn't go negative until later in June 1889.

The global circulations responded sharply towards the end of July, 1889 hence the cooler than average August/September in your region. So, again, yet another analog supporting the idea of a midsummer transition to a cooler pattern. As for the MEI data, it's funny because that link was on the same page I get my ONI data from.

For example, here's Downtown Portland's average summer highs from 1875 to 1904 (first 30 years of the station existing), with PDX's 1981-2010 averages in parentheses: June: 71.6 (73.5) July: 77.6 (80.6) August: 77.4 (81.1) September: 71.1 (75.8) So while August and September 1889 in Portland look very cool by modern standards, it wasn't cool at all for the standards of the late 19th century. August 1889 had an average high just a tick below average and September was +2.3 on the average highs of the late 19th Century. Quote Link to comment Share on other sites More sharing options...

What stands out to me is that 1889 was obviously a very dry and sunny warm season from April - October. You can tell that by the wide temperature ranges on most days. I am not concerned at all about being 1 degree below normal or 1 degree above normal compared to the 1981-2010 average. If it is that dry and sunny in 2016... then it will be a great summer and fall. And likely noticeably warmer than 1889 with all things being equal.

I would love to follow that year and the full year Nina of 1890.You can eliminate that issue by using an 1879-1900 baseline relative to observations in 1889. Still flipped colder than average in your region during the second half of summer using that baseline. Either way, the climate warming you're referring to isn't enough to make a statistically significant difference in locally derived temperatures in analogous patterns on seasonal/subseasonal scales. Perfect weather from April - October in 1889... very snowy January... and then amazingly another warm and sunny spring in 1890 and a perfect summer with almost no rain from June - October. That is with a Nina in place all year.What's kinda funny is you've consistently mocked Jim for hyping old analogs from the 1800s. Now, the tables have turned and you're relying on a single analog from that era to justify your wishcast, because there are no viable modern day analogs to your liking (1998 isn't a viable analog at this point). 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...

August 1889 had an average high just a tick below average and September was +2.3 on the average highs of the late 19th Century.Just adjust the baseline. Still was a cooler than average J/A/S aggregate.

TT-SEA Posted April 25, 2016 Report Share Posted April 25, 2016 What's kinda funny is you've consistently mocked Jim for hyping old analogs from the 1800s. Now, the tables have turned and you're relying on a single analog from that era to justify your wishcast, because there are no viable modern day analogs to your liking (1998 isn't a viable analog at this point). Jim and I both love the 1889-90 analog. So its not really tables turned. There are really just 5 years to pick from if we are going from a strong Nino to a strong Nina and doing it rather quickly. 18891942197319881998 The best solar match of these is 1889... by far. Not sure what else to say. We also had a warm, dry spring in 1889 which is making it more of a match as 2016 reveals a rather warm, dry spring so far. I have said I would have enjoyed the JAS period in every one of those years. I am not cherry picking 1889. It also had the cooler August and September. And would certainly be a winter that Jim would love. If I was cherry picking a year to be jerk... why would I pick a year that Jim would pay money to repeat? I would give my next few paychecks to have a season play out like 1889-90. Is the best ENSO / solar match. That is always my starting point. It is what it is.

The antecedent ENSO/forcing state will represent neither during the boreal summer. What you want to best capture, in my opinion, is the timing, structure, and rate of a given ENSO flip. So, you can set looser standards in terms of strength/etc. Also, if you're going to factor in solar (nothing wrong with that) you'll need to factor in the QBO, too, as it's the major conduit through which solar forcing affects the troposphere.

I don't think 1889 is a bad analog, but it's very, very old and a number of things have changed since then. So, personally, I'd want more than just one ancient year in my analog pool to feel confident. That's just me, though.

Jesse Posted April 30, 2016 Report Share Posted April 30, 2016 You are so strange.We have differing opinions. Let it go. I like snow, crisp October days, cool summer evenings, sub-freezing highs, mid-April graupel showers and strong marine pushes. Haven't seen much of any of those in the last few years. It's like missing old friends I grew up with. Quote Link to comment Share on other sites More sharing options...
