griteater Posted August 17, 2015 Author Share Posted August 17, 2015 This nino continues on a track towards being a big one when looking at SSTs, VP anomalies, EQSOI, and 850 zonal wind anomalies. The SST evolution and model forecasts suggest more of a basin wide event, while the current VP anomalies suggest more of an east based event. Either way, I think we see pre-dominate 500mb negative anomalies in the NE Pacific this winter. Using a combo of SSTs and the MEI, there were 2 big ninos in the late 1800's. Combine those with '83 and '98, all of which had +PDO setups, and we get a similar big picture pattern... The next set down of strong ninos would include 1973, 1931, 1903, 1941, 1966. I don't like 1973 or 1966 due to those having a -PDO regime which has implications on the resultant north Pacific pattern (Aleutian Ridge / W Coast low in those years). The '31 and '41 winters had more western Canada ridging and SE troughing (+PNA), and a lot of the seasonal modeling has this look (JAMSTEC, Euro Seasonal, CA SST based model, CPC outlook, CANSIPS, UKMet) so we will have to see how those trend over the next couple of months. Edit: in contrast, the CFS and POAMA look more like my composite above Link to comment Share on other sites More sharing options...
SN_Lover Posted August 17, 2015 Share Posted August 17, 2015 Dont take this wrong...but Are you serious? AGW is real but there is zero literature to support your post. It's just regional variability. While yoUr area has experienced below normal other regions have experienced much above normal. I encourage you to read the IPCC reports carefully, most notably the 2007 report which outlines RF's and everything i discussed. There are many books such as Introduction to Modern Climate Change, Andrew Dessler, i can provide you that i read in my undergraduate years if you PM me. That concludes my Global Warming posts lol Link to comment Share on other sites More sharing options...

mackerel_sky Posted August 17, 2015 Share Posted August 17, 2015 This winter will be cold and wet or cool and wet or warm and wet, I think cold and wet , is off the table! We will see above normal snow or below normal snow! Link to comment Share on other sites More sharing options...
Cold Rain Posted August 17, 2015 Share Posted August 17, 2015 At this point, it's difficult to understand the impact of climate change on specific regions of the globe at specific times of year. We do know the sun has cycles, the nao has cycles, the pdo and amo has cycles. Based on the comments above, maybe the best correlation to snowfall in the SE is the nao, which is probably not all that surprising. I don't like the thought of a strong, east-based nino. But a basin-wide event with a strong +pdo would be interesting...especially with declining solar and a propensity for a -nao. The last variable seems to be the least confidence of all, though.

stadiumwave Posted August 17, 2015 Share Posted August 17, 2015 I'm watching this thread carefully. We will not be getting into a global warming argument here. If that is what you re looking for, take it to the Climate Change forum. I'm not looking to get into one, but the poster is posting false information. He's taken a broad AGW possible future climo & applying it to a current regional variability. Is it not ok to respond? I'm not arguing AGW (I'm no skeptic) but I am against a poster taking accurate science & making a false application to it concerning his area's snowfall.

NRVwxfan. Posted August 17, 2015 Share Posted August 17, 2015 One thing that should be noted is that analog's are becoming less useful. I hate to talk about this on the weather forum, but since this is climo i am. Global Warming is reducing snowfall overall for all of NC at a fast pace. So previous decades "snowfall analogs" should be used with caution because if the same pattern shows up, it will be warmer than the analog year. Really dude? Please leave the Global Warming stuff on the climate change forum. Link to comment Share on other sites More sharing options...

It is not necessary to respond because we all have brains of our own. Now, the bigger reason might be that this seems not to want to die after I posted to drop it. So, I am telling everyone now, the next mention of this and I will delete every post in this thread from the first mention of global warming up to an including the above quoted post.

CAD_Wedge_NC Posted August 17, 2015 Share Posted August 17, 2015 One thing we can reasonably count on, is it being a wet winter. As far as the cold goes.... it's a crap shoot right now. There are indications of a warm NE pacific holding on causing a +PNA. However, this is far from certain. One thing to look for, is how the Pacific flow sets up in Oct / Nov. If we see a lot of Aleutian lows, then we will know. The "re-curving tropical system" theory has some merit when it comes to getting cold in the east. It can trigger a good pattern, but that's still too far out to speculate. Bottom line is that we don't know how our snowfall chances will play out this winter, but we should count on plenty of wet weather. Since we are in a drought, this should be taken as wonderful news. Our higher elevation folks should see a banner snow year with all that moisture around (even if temps are at average) Link to comment Share on other sites More sharing options...

One thing thats pretty likely is it will be stormy. Link to comment Share on other sites More sharing options...

superjames1992 Posted August 18, 2015 Share Posted August 18, 2015 What is that line? Plot a 30 year running average...below is RDU's 30 year running average going back to the 1880's. You can see the cyclical nature of it. Interesting graph. I take it Greensboro used to average over 10"/year once upon a time, then. Maybe the city will average that total again in 20 years, though I might not still be living here then. Link to comment Share on other sites More sharing options...
