I’m sure many of you are familiar with Ylvis’ international hit: “What Does the Fox Say?”. I’ve heard the song once or twice, and that’s one or two many times too many. The fox does not say “gering-ding-ding-ding-dingeringeding” or “Wa-pa-pa-pa-pa-pa-pow.”
The fox goes “WAArra!!!” Everybody knows that. So what’s with the annoying song?
A far better question is “what does the model say?” Here, we can look at the various models and interpret what they are saying. No need for any of that ring-a-ding-ding nonsense. However, because models make no sound, if one wanted to write a song about the varying statistical output of models, it would have to be called “What Does the Model-Watcher Say?”. “I LIKE THE 500mb PATTERN” or “NEED MORE CAPE” (convective available potential energy) or “WHERE’S THE RAIN SHADOW” could be lyrics, and they’d make more sense than “What does the fox say (bass drop, cue jibberish).”
But this blog is in written form, not audio form, so we don’t need to worry about any of those logistics. Let’s take a look at what some of the models are saying.
First, let’s look at some important differences in this evening’s (00z) runs from those this morning (12z). The ‘z’ is just a synonym for UTC or GMT (Coordinated Universal Time or Greenwich Mean Time). The 12z MM5-NAM had a deeper low than the 00z, but the 00z WRF-GFS was stronger.
Sorry for this brief change of subject, but the fraternity next door (Phi Kappa Sigma/Phi Pools/Pi Fools) just started playing that fox song. Let me get my earplugs real quick…
Alright… ear plugs are in. Back to weather stuff.
