You seem to know a lot about weather, so apologies if this comes off as a stupid question.
What value add do companies such as AccuWeather and others provide over simply going to weather.gov? Is their UI simply better, or do they run their own weather models? Thanks
- chipsa 6y agoCompanies very rarely run their own weather models. This is because the models require a ton of computing power. Ex: the USAF current weather model is run on "Thor"[0][1]. It's a .9 PFlop system. And it uses approximately all of it, on a consistent basis. If it didn't, they'd increase the model resolution to match, or run the model more often to incorporate observed data faster. Most of the companies like AccuWeather et al provide, is better UI, and tailored weather. Not just there's going to be a severe thunderstorm, but "these truck routes are going to be affected by weather, so expect them to be 40% slower than normal" or similar.
