3-year trends to November 2013

Trends to November 2013.

Most raw anomaly values (orange) for November climate variables remained on the “drought” side of normal, but less extreme than in October. As an exception, rainfall was very high.

Fully-smoothed data points (red) for autumn (MAM) of 2013 show a climate that was normal in the context of the decade beginning April 1999. Anomalies were high cloudiness, low dew point and warm subsoil. The last fully-smoothed data point, for May 2013, moved towards drought.

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.
