“June 2015: back to normal”
June raw anomaly data (orange)
Nearly all raw anomalies for the latest month are nearer to normal than the partially-smoothed anomalies of the autumn months. They are also quite close to the smoothed values of a year ago. Rainfall stands alone as a high value.
Fully smoothed data (red)
In December 2014, most anomalies were normal, or near normal, and changing only slowly.
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.
