Humidity Trends In The Uk

Hi All,

I am trying to find some background data on humidity in the UK & hopefully a way of gaining live (and recent) data.

I have looked on the met office website, all I could find was temperature & rainfall data.

Any pointers would be gratefully received..

Thanks

Richard

Hi Richard,

I've provided a couple of links that may be of interest. They're gardening and agriculture based but they do provide some good data on climate change in the UK including on humidity.

Simon,

Many thanks for the links -

The point that I was hoping to prove has been stamped all over..

My assumption was that increased rainfall + increased temperature = higher levels of evaporation = higher humidity

Apparently not..

Anyway BTW.

Richard

Whilst we're on it, where does humidity come from then?

Errrr, moist air??

Ok thanks.

Why not? Is humidity going up?

Ah Simon,

You obviously did not take time to read the article that you posted.

My brief interpretation of the many pages of text.

Higher Temperature means generally less cloud cover, when evaporation occurs, instead of it being caught in the big fluffy things it dissipates into the outer atmosphere leaving a net water loss.

When we do have rainfall it will be more intense (tropical storm), where we will have short blasts of high humidity / rainfall, but this is soon over.

Apparently this is all bad news for the horticulturalists.

You're right I didn't read it all. Too busy immersed in the new BRC/IoP Packaging Standard at the moment.

Thanks for the summary.

I always thought atmospheric pressure came into it somewhere???

The UK seems to have high humidity WITH cloud cover.

Bring on global warming

You're correct about atmospheric pressure, this does have an impact also.

I'm not sure of all the ins & outs but the RHS summary is that humidity levels will be decreasing.

You can just imagine all the UK seaside resorts that have lay dormant for the last 40 years rubbing their hands in anticipation of global warming
