Question: Why does it always rain at the weekend?

Answer: It’s our fault, all this pollution.

Clouds are made of water vapour, lots and lost of tiny water particles, but without the presence of dust, upon whose surface the water generally can gather, water vapour wouldn’t begin to condense until the relative humidity reached 300 percent.

So dust helps to form clouds, and as humans, we are producing one hell of a lot of dust - how does one effect the other? The answer may have been found in a study of the North East Coast of America, where it was found that the weather seemed to be following a 7 day pattern. Nature doesn’t generally follow 7 day patterns, they’re a human invention, so it seems that the weekly driving, combusting and manufacturing creates a 7day dust cycle which crescendos towards the weekend, and leads to the statistical fact that slightly more rain falls on a Saturday than the rest of the week.;jsessionid=1A5CE633A5BDFB8B7C1C1C90690F9387

American Scientist claims dust could be responsible for coral reef deterioration in the Caribbean. Saharan desert dust has given a trans-Atlantic ride to bacteria and fungi which then settle into the warm waters of the Caribbean.

Further to my post on the other forum:

Question: Why should you not eat yellow snow?

Answer: Because it may contain heavy minerals and pollutants.

South Koreans have been warned this week to stay indoors or wear protective masks, after an outbreak of yellow snow on the peninsula. The snow which contains dust from the Chinese deserts could pose a health hazard as it contains “heavy minerals and pollutants“, says the local meteorological office.

Earlier Notes:
The Sahara is probably the biggest supplier of desert dust in the world, and a bit of dust can travel a long way. Montain geologist Anders Rapp, reported in "Yellow snow over the Alps and Subarctic from dust storm in Africa, March 1991" that the occasional yellowing of alpine and finnish snow is down to these dusts.

Dust is not always the reason for yellowing of snow - in Pennsylvania, local pollen can be to blame - and indeed yellow is not the only unusual colour. The alps have also seen blue snow, caused by Saharan copper-salts and red snow has been noted in the arctic, caused by red-tinted, microscopic plants and animals.

Anyone know what particular health hazards these "heavy minerals" could cause? I assume some kind of respiratory problems, or could they contain lead or even radioactive dusts?

New study confirming what we said about wet weekends on the show last year.

As far as I can remember (brilliant source, eh?!) Wednesdays are usually very fine - due, then, to the weekend dumping.

Retraction special perhaps, latest study says that it rains less at the weekend. Still due to pollution though.

Steve Wright on his Radio 2 "factoids" segment has it that it rains more on Thursdays than any other day of the week. Not that he's infallible, by any means...

Can I just point out that Sod's Law has yet to be mentioned in this discussion?

Am I the only plebian on the forum who read this thread title and instantly thought of Marjorie Dawes on Little Britain?

No, you're not! : )
