Calculating daily average and triggering event when condition applies for 5
continuous periods
In this previous example it is demonstrated how to observe the beginning of
"Thermal autumn". Thermal autumn is defined to begin when "Daily average of
temperature" has not exceeded 10°C for five days. Here it is assumed that starting
date would be the end of the 5 days period rather than beginning of the 5 days
period. More formally
MAX(5Days) {AVG(1Days){temperature}} < 10°C
This should be evaluated each day for last five days to observe the event as soon as
possible.
