Weather and Social Media Sites Discussion


IsentropicLift

Recommended Posts

Instead of clogging up a storm discussion thread with talk about weather and social media sites I figured it would be better to make a thread to discuss it.

 

In the world we live in today everyone has access to computer modeling. You can't stop it.

 

Everyone, or just about everyone is also on FB and Twitter.

 

The combination is both frustrating and potentially damaging.

 

It's irresponsible to post snowfall accumulation maps on social media sites, particularly something as stupid as an EPS control run total snow map. It spreads like wildfire and causes nothing but headaches for the real people responsible for issuing forecasts.

I'm the local "weather geek" at my job. Several of my co-workers and my boss started asking me about this when it first hit social media and some TV news. I told them that it is way too early to tell anything just yet. There is a possibility of a storm somewhere along the east coast. We will know more if/when towards the end of the week. My boss then asked me what the European model showed. That started when media started naming that model as the one showing that Sandy will be a direct hit on the U.S. I think the public has been wrongfully educated by these instances.

It truly is scary how one person posting an image like that, can affect the entire population of the northeast. It spreads like wildfire.

I've had multiple people come to me at work saying we wre getting 2-3 feet of snow this weekend.

It spreads to anyone and everyone. It takes one person, and in a day, anybody who is on twitter has seen it.

Absolutely. Then that model printout from last years storm started making the rounds on gawker. The 30" vs. 3" side by side maps. All it takes is one person with a decent amount of facebook or twitter followers to post it and it just explodes. Because people don't read or understand, even a disclaimer like 'this is not my forecast just what one particular model is showing' isn't good enough. People just need to stop posting anything like that.

It happens in many other situations too, when something that is untrue shows up on social media and goes viral.  The best example I can think of is when rumors start of a celebrity dying or some celebrity couple getting divorced.  Honestly, what should happen is that these Facebook pages that pertain to an important aspect of life, let's say health, news, weather, should be somewhat regulated.  These weather pages on Facebook have huge followings and the people who run them have nobody to answer to.  For example, last time I checked Tri-State Weather had over 90,000 likes and the local guy who does it in my area has over 60,000 likes.  These guys that I mentioned actually do an amazing job and don't hype storms at all, my point is that having a well liked Facebook page is a very powerful thing.

I wouldn't even post a map showing 30" accumulations if it was the day before the storm. It's not my job to give forecasts. That's up to the professionals that know a hell of a lot more than I do.

 

No maps should ever be posted unless you're using it to justify your own forecast. Its way too confusing for the general public to understand the difference, sad as that may be.

 

People see pretty pink colors showing 2 feet of snow and they don't hear or see anything that follows

I couldn't agree with this sentiment more.  Instant access to information for all isn't always a good thing, like when you see people posting 384hr GFS maps on Facebook.

Did you guys read JB tweeting about the Mt. Holly briefing?  Basically called them out for missing the Monday snow on Friday.  That storm first showed on Thursday I believe, and was initially modeled to be either a near miss or a nuisance event. 

 

So who will call him out if our big weekend storm that he said would still happen goes OTS?

I think we need to make a concerted effort to educate people on the borderline unfathomable complexity of the atmosphere, and how consequently we don't have near the computing power yet to accurately model it that far into the future.  Nate Silver wrote a great piece in his 538 blog a year or two back about meteorology, big data, and high-performance computing (http://www.nytimes.com/2012/09/09/magazine/the-weatherman-is-not-a-moron.html?pagewanted=all).

 

I wanted to start a thread on this particular point some time back, but I figured I would wait until after winter.  According to the article (mets, feel free to correct), the atmosphere has something on the order of 1044 molecules.  We'd have to be able to sample and model every single one in order to totally model the atmosphere for use in future prediction.  Given the non-linear nature of the atmosphere, this would require (assuming we could actually sample every single one, a feat virtually impossible as we know it today) processing power well beyond what we have currently.  The fastest computer in the world right now is in China, and has achieved approximately 30 petaFLOPS, or 30 quadrillion floating point ops per second.  We are projected to reach exascale computing sometime around 2020 (exascale computing = 1 exaFLOPS, or 1 quintillion floating point operations per second).  I think if we can get up to around 100 exaFLOPS, we might have the capacity to model everything, but realistically with current silicon-based chip technology that won't be possible.  Luckily work being done with carbon nanotubes and graphene will hopefully help us move past the silicon-chip era.

The worst part is JB defending the posting of the 30" snow map saying its not the same as yelling fire in a movie theatre...uhh yeah it kinda is

Perhaps the NWS needs a greater presence on social media.  The only people seeing these briefings about social media hype are weather geeks like us.  Meanwhile, millions of people see a 384 hr Euro control map showing 40" of snow, or an old RPM model run from last year showing 30" in NYC and panic sets in.  Just to use the local Facebook weather page as an example here, he has over 60,000 followers, while the NWS Albany (which covers my area) has 10,000.  A concerted effort by the NWS to increase their social media exposure and then in turn use that power to educate the masses about long range weather forecasting might be beneficial.

Meteorologist Mike Faveretta from News 12 Brooklyn

Out to Sea?

"Not so fast…before we write off Sunday's storm just because some "models" say so, let's remember what has happened for almost every snow storm this past season.

7 days before: the forecast looked disastrous with a monster storm.
4-5 days before: the storm seems to "disappear" on the weather charts.
3 days before (now): the storm is re-appears, but it stays just to our South.
1-2 days before: the storm jogs further and further north, with every 12 hour update, slapping us with last-minute, largely unexpected snow.

Are we going to get fooled again? No! Let's err on the cautious side and keep snow in the forecast for Sunday. Will it be monstrous? Probably not, but it will still snow during the latter half of the weekend, beginning Saturday night at the earliest. I'm thinking manageable: like a 3-6" deal, ending Sunday. If all goes to plan, kids and parents should be able to get to school and work without much hassle on Monday.

Wednesday could be more significant. More on that tomorrow.
