“Retreat from cold wet extreme”

New raw data for March 2012 anomalies show a retreat from low extremes towards normal for maximum and minimum temperatures, and temperature range. Rainfall (perhaps temporarily) moved to negative to positive, and subsoil temperature from negative to positive. Cloudiness remained very high, and Dew Point very low.

Fully-smoothed data points for September 2011 include a new 13-year record high monthly rainfall anomaly of +28.6 mm (first graph). This beats the record of +20.0 mm set in November 2005. The new record is sure to be beaten by October and November 2011 when their values can be smoothed.

Although the smoothed value for maximum temperature anomaly in September 2011 was not very low, the smoothed value for December 2011 may reach a record low.

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.
