humidity is the percentage of water saturation of the air. air at 0 degrees can hold little water vapor while air at 100 degrees can hold alot. this is why a cold glass on a hot humid day will "sweat". the air being cooled on the cold glass cannot hold its water anymore and the excess vapor condenses on the glass. so the humidity percentage given is relative, not absolute. the amount of water actually in the air at say 50 percent depends on the air temperature.


look into the sky. as warm air rises off the ground it cools off in the higher atmosphere. at some point it will cool off far enough to reach 100 percent humidity and the excess is the vapor that forms clouds, actually big congregations of little floating droplets. enough floating droplets and something for them to condense on (floating dust) and the droplets get too heavy for the updraft to hold and you get rain.

Hi thanks Reso.... that at least made sense ,I should have remembered that from school , but LOL that was many years ago

Oh S**t I have left the covertible out with the roof open, gotta go

You could be right Tommie , you given it up ? I am just getting the hang of it , 

  ,  nice odds  ;)
Stop Press, by the time I stagered to the car it had stopped raining ,

Hi guys thanks for the posts , It helped with the British obsession with the weather, 
  just some tourist info on weather in Great Britain


"The United Kingdom  is situated off of the northwest coast of Europe, these islands extend between 50° and 60°N. The climate of Britain is notoriously variable and changeable from day to day. Weather is generally cool to mild with frequent cloud and rain, but occasional settled spells of weather occur in all seasons.
Visitors to Britain are often surprised by the long summer days, which are a consequence of the northerly latitude; in the north of Scotland in midsummer the day is eighteen hours long and twilight lasts all night. Conversely, winter days are short.
visitors will rarely experience severe or unpleasant weather for long unless they venture on the hills. They should be prepared for rapid changes of weather at all seasons,  and recognize that there is good reason for weather being a major talking point in Britain."   
 
now, it is the price of petrol /immigration/ income tax , 

we are not really obsessed by the weather ,  by tradition it is used as a coversation starter between strangers , you can hardly say to a stranger "got any pictures of your wife,   naked "
well not until you have finished talking about cricket, and Englands chances of winning the ashes,  

thanks for all the facts and figs. from your area, you sure do get some extremes , makes me feel a wimp 

   Regards Roco  UK   
one for     Reso......
 as I think he understands English ascents well , if you ask a English Public school boy to say   "particularly nasty weather" , it sounds just like "tickle your arse with a feather"   
as seen on Brit TV many years back ,
 

yes there is nothing to beat 10 days of overcast and drizzle ( mid November)
oh Jeez only 4 and a bit months before that delight returns 
and the 7 hours of dim daylight, 
but considering the northerly latitude we average winter temps. of around 34-35F and very little snow if any in the London area , we get free heating from the gulf stream comming over from your side of the pond , making the UK 10F warmer than it should be ,but if the wind blows from the north east we get Moscow's finest , then it is cold ,
