We know that anticyclones can last for days, weeks and months and are classed as blocking anticyclones.
I was wondering if anybody knows the following information:
1) why do they last in an area (Britain for example in 2003) for a long time and then eventually clear and move away
2) If high pressure moves to low pressure, how do blocking anticyclones last.
Any information on this would be really helpful for a presentation I'm doing!
I'm going to quote in Tank Girl now so she can move your thread to the right place if it's needed.
