Rainfall on Ochre Arch 2007 and 2008

Posted by Picasa

The attached image shows monthly rainfall on Ochre Arch for 2007 and 2008, together with estimated monthly rainfall based on figures from a neighbour kept over in excess of 45 years.
Actual figures for the years are 2007: 380 mm, 2008 473 mm, long term 600 mm
Some of the key messages are:
1. Rainfall for the past 2 years has been substantially lower than the long term figures. That said, one could well ask the question "Is 45 years really long term"?
2. On 5 out of 12 months in 2007 and 3 out of 12 months in 2008 the monthly rainfall exceeded the long term monthly figure of 50 mm.
3. Yes - it remains dry!
