All weather explained

[sawyl]

Despite promising to tell me everything I ever needed to know about the weather, today's Guardian still didn't explain Gaussian grid resolutions — something I've been vague on for years. Thus, when people talk knowledgeably to me about N540 or whatever, I just nod and smile and try to hide the fact that I don't even have the first clue how any of it maps to real world resolutions.

Why don't you ask ?

Thanks for that, but I think I've pretty much cracked the problem. I went back to first principles, only to discover that the process of converting from N resolutions to km is actually as simple as, l = 13,300 / N. So it turns out to have been no great mystery at all...
