100%. The foundation of NWP is chaos theory. I don’t believe most in here understand this, or they think they do but in reality, they don’t at all. They’ve never seen it demonstrated, explicitly.
This stuff pisses me off to no end because the physical equations are robust; it is rock solid theory. It’s the future telling that causes the significant error bars; especially 5 days + out. It’s the addiction of wanting to see the future which has people abusing the modeling tools available to the general public and entrenching in the masses minds that atmospheric science is more BS than macroeconomics.
Taken together, observations are far more powerful (skill-wise) than hypotheticals built on representations of the global atmosphere 2 weeks+ out which are then used to make regional forecasts. No Skill! In other words, more work analyzing does NOT translate to more accurate forecasting results. It just means more jargon and BS explanations that dupe the naive and ignorant, “this guy must know something.” It also means forecasting accuracy is likely lower because it is more clouded, staring at variables as if they are knowns, when in reality they are unknowns because at future time points they are very poorly resolved or not resolved at all.
When it comes to complexity, most often, the simplest explanations are the most accurate ones.
