Trends to June 2010

Raw data for June 2010 (orange) are mainly near the smoothed values for January 2009, 17 months earlier. As an exception, the minimum temperature anomaly was very high, making the daily temperature range very low.

The last fully-smoothed data point, December 2009 (red), had hot days with a slightly lower daily maximum temperature anomaly than the record set the month before. Rainfall anomaly during this “drought” peak was not very low at all (-16 mm). Other variables for November 2009 were near normal, except daily minimum temperature anomaly, which was a record high value of +1.31 degrees.

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.
