You've lost me totally there mate! I haven't a clue what you're talking about!

I'm getting english from, "oh oh oh" onwards?!

Thanks for your answer Paul. Not being a scientist or a climatologist these are questions I need answering. This is a public forum and as such most questions will be asked by people without meteorological diplomas!
Maybe I should just spend the rest of my life researching every question in my head then I will never need to ask a ridiculous question again because I will have all the answers.
