Trends to November 2014

November data (orange)

The raw anomaly value for daily maximum temperature became extremely high: +5.1°. (The record positive anomaly was +5.6°, set in November 2009.) There were also extreme “droughts” values for high daily minimum temperature, high daily temperature range and low monthly rainfall. Values for cloudy days, dew point and subsoil temperature were near normal.

Fully smoothed data (red)

The latest fully-smoothed data (May 2014) complete the season of autumn 2014. The movement away from the mild drought of late 2013 ended in this month. Rainfall was rather low, skies rather cloudy, dew point low (near a new “normal”), temperature range and subsoil temperature normal.
Contrariwise, the smoothed anomaly of daily minimum temperature peaked in May 2014, showing a more maritime climatic episode.


Note:

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.
