3-year trends to November 2016


November raw anomaly data (orange)

In November 2016 the daily maximum temperature anomaly rose sharply to a high value. Moisture variables also moved high on the graphs: Temperature range became very high, rainfall low, dew point low, and cloud below normal. Daily minimum air temperature and subsoil temperature (bottom graphs) remained extremely low.

 Fully smoothed data (red)

The autumn months (MAM) of 2016 are now fully smoothed. Daily maximum temperature moved down into the normal range. All moisture values increased, but only the rainfall and daily temperature range were in the normal range of values: skies were more cloudy than normal, but the dew point was below normal.
Daily minimum temperature and subsoil temperature rose slightly during the autumn season. However, while the subsoil temperature was normal, the daily minimum temperature anomaly reached a new record high for a smoothed value in May 2016: +1.34°, beating the value of +1.32° reached in December 2009. This variable may peak in June 2016.


Fully smoothed data – Gaussian smoothing with half-width 6 months – are plotted in red, partly smoothed data uncoloured, and raw data for the last data point in orange. January data points are marked by squares.
Blue diamonds and the dashed blue rectangle show the extreme values in the fully smoothed data record since September 1999.

Normal values are based on averages for the decade from March 1999.* They appear on these graphs as a turquoise (turquoise) circle at the origin (0,0). A range of anomalies called “normal” is shown by a dashed rectangle in aqua (aqua). For values in degrees, the assigned normal range is +/-0.7°; for cloudiness, +/-7%; for monthly rainfall, +/-14 mm.

 * Normal values for rainfall are based on averages for the 125 years beginning 1883.
