what about these rains of fish and frogs? what article would talk about them? - Omegatron 16:19, Oct 22, 2004 (UTC)

What an awesome page - this is one of my favs. Not least because of the beautiful photography of course, but the article is really top notch. I love rain. --?

What is the difference between "showers" and "rain" as reported by meterologists? I have heard that the former is intermittent and the latter is constant, but also that the former is caused by cumulus clouds and the latter by "strato?" clouds. Which is the true definition? --Mintie 28 June 2005 23:08 (UTC)

What speed does rain fall at?

All things fall roughly at 9 meters per second.

Is rain water usually potable? --TheSimkin 16:58, August 7, 2005 (UTC)

I think so, but I'm not sure...search around a bit :D —CliffHarris (-T|C-) 01:43, 19 March 2006 (UTC)

There is no guarantee that rain water will be potable. Strong winds, especially those associated with storm cells can trap material from the earth's surface including soil, dirt, small animals and fish, sea-salts etc. all or any of which can then fall as rain. Calm weather convection rain and rain associated with wet trade winds are probably of a quality suitable for drinking but this can never be guaranteed. Concerns about the acidity of acid rain affecting potablility are almost certainly misplaced. The ionic concentration of Acid rain is so low that despite the very low pH there would be no adverse impacts from drinking such water.

In the 1960s when aircraft were allowed to discharge their seweage waste into the atmosphere, there were some recorded occurrences of Cholera transmitted via rainfall (I'll try and find the reference)

How about artificial rain?

i've heard that sometimes clouds are "moved out" (on parade days, for example) to guarantee that there will be no rain.

On the other hand, i've also heard about "ordering" rain, to compensate in case of too much dust in the air. Thank you in advance for the response, JAUI (25 April 2006)

There are cloud seeding services available--you can pay light aircraft to spray silver iodide dust that (theoretically) can nucleate clouds and cause rain.

Cloud removal I haven't heard of. Clouds only seem to move in response to winds and temperature/pressure variations--possibly you could focus a lot of heat skyward to push them away, but that would be a LOT of heat. Possibly someone's been selling "rain removal services" ... but I'm not sure how scientifically based that is. Even the usefulness of cloud seeding--a semi-well studied technique--is still up in the air.JDowning 18:44, 25 April 2006 (UTC)

[edit] why it rains mostly in the afternoon !

Where I live, there are frequent thunderstorms that occur during the day. But why does it occur mostly in the late afternoon (starting around 5-6pm)and then clears up.

I love rain, specially when it brings thunder. Falling asleep with heavy rain and thunder in the backround is awesome. Reminds me of "winter" in El Salvador :-) Guanaco152003 01:00, 31 December 2005 (UTC)

I also love rain. Taida 02:16, 16 June 2006 (UTC)

Rain is nice. *sighs* -- the GREAT Gavini 17:04, 6 October 2006 (UTC)

[edit] Removed from page for discussion

I've removed the recently added note:

The formation of rain droplets from vapour in the atmosphere can be modelled using simplified applications of Jamesworth Pilley's molar gas theorem, which also makes use of the notable chemists' constant.

as it is unsourced, and Google search returns a total of one hit on Jamesworth Pilley - and that is to another wiki article. - Vsmith 16:41, 12 January 2006 (UTC)

[edit] About the picture

The picture of rainfall in the top-right corner - is it real? Sure looks like a photoshop tutorial.. Well, anyway it sort of displays rain..(Henningklevjer 15:37, 24 June 2006 (UTC))

[edit] Rain drop picture

Can someone please change the rain drop picture. The picture shows drop after it has bounced back, so the shape is not correct. Usual rain drops are not spherical, because of the shear forces acting on them. YashKochar 20:18, 4 September 2006 (UTC)

[edit] Stream Rain

This article only documents rain in droplet form. However, it is known(especially near the equator) to fall in streams(like your shower) or even what looks like a solid wall of water(torrential rain). Why are neither of these types of rain documented? —The preceding unsigned comment was added by 12.197.249.26 (talk • contribs) 10:50, 3 December 2006 (UTC). Uhh hello, I did ask this for a reason.

[edit] Poly water

Water forming chains after lightning? Can we have a source for this please? Mullet 21:29, 12 December 2006 (UTC)
