I've been an Air Force meteorologist for almost 20 years, never heard of that rule.

...never heard of it...possibly a 9-day rolling average, but I can't imagine why.

On second thought, a Fahrenheit degree is 5/9 of a Celsius degree.

rainfall for the nine-month period works out at 89% of the long-term average.
