Title: If it rains more here, does that mean it rains less somewhere else ?
Post by: neilep on 21/07/2007 18:25:16

Hello Rain People,

Do ewe know what the avreage EARTH rainfall is ?...is it the same each and every year ? (say since records began)

We are having a lot of rain here in the UK right now !...Does this mean somewhere else in the world they are having less rain because of it ?

Is there a state of equilibrium at play here when it comes to weather ?

Thanking Ewe for your kind considerations in this matter.

Le Sheep.

We getting a LOT less rain. I don't know if that is true or not, but I'd have to say no beacuse there is rain that gets deep under ground and takes billions of years to get out. And I don't know what a state of equilibrum is.

Thanks Ryan, (It is Ryan isn't it ?)

What I mean by a ' state of equilibrium ' is  that as a planet , though we may have extremes of weather, are the relative extremes counteracted all over so that the amount of weather we have is equal the world over ? ..ie: a balance of opposing forces !....do ewe know what I mean geeza ?

Yes it is Ryan..

I think I get it now..I'll tell my Science teacher and they will say your smart here a is 4.0. Not going to happen. LoL.

Yes and no.

The rain we have at present was said to be rain that normally falls further north, so there are certainly cases where rain is simply taken from one region to another.

On the other hand, the amount of water in the atmosphere that is available throughout the globe can vary (and one would expect that as the world gets wormer, more water will evaporate to be available to form rain, but where that rain falls can be variable.

The rain we have had over the last few weeks is actually not that unusual for what would have been normal a few decades ago (we have just got unused to it over the last few years).  The floods we have had recently has not because of unprecedented rain (high rainfall, yes; but not unprecedented), but more because we have tarmacked so much more of the land that we have given the rain nowhere to soak away.
