Looking at the ACCESS-R Meteogram What is the relationship between the %ages for Low, Middle and High cloud cover and the Total cloud cover figure? ie. the three cloud cover columns (low, middle and high) often don't add up to the Total cloud cover %, why is that? Eg. Tues night in Canberra is showing zero% Low, Middle and High cloud up to 01:00 but 72% Total cloud from 22:00..?
