- Averages so far this year:-
- Average CET to October: 7.95
- Normal CET to October: 6.48
- Anomaly to October: 1.48
- Anomaly to November (year so far) *: 1.55
- Comparison with Extreme Annual CETs:-
The highest annual min CET ever recorded was 7.3, which is 1.46 higher than normal. To beat this record the
anomaly must be higher than 0.78 for the remainder of this yearThe lowest annual min CET ever recorded was 4.33, which is -1.51 lower than normal. To beat this record the
anomaly must be lower than -25.09 for the remainder of this year
* The anomaly for the year so far to November is calculated by taking an average
This year's Daily Data to
date
of the monthly anomalies, weighted by the days in the month so far, over the total days in the year so
far.
This prevents the year so far anomaly value being skewed when calculated at the beginning of a month.
Note that anomalies (and normals) quoted here are w.r.t. the period 1961-1990. This is a standard
period
of reference for monitoring climate change as recommended by the WMO (World Met.
Organisation).
