Annual temperature seasonality and annual precipitation seasonality were calculated as the square root of the difference between mean annual maximum and minimum values.

why not just use the actual values for the different seasons? McCallums two papers in combinations with studies cited within demonstrate that annual variation is pretty much no useful, you must examine each season because small variations in some seasons (T & P in winter) can be much more important than the same variations in summer for example.

No competing interests declared.
