“February 2015: very dry”
February raw anomaly data (orange)
In February, most anomalies moved back towards “droughts” from the “flooding rains” values of January. Rainfall became extremely low, but daily maximum temperature did not rise as far as “normal”.
Exceptionally, February daily minimum temperature and subsoil temperature became very low.
Fully smoothed data (red)
The latest fully-smoothed data anomalies (August 2014) complete the winter of 2014. Through the winter season, most values were static and near normal. (Dew point, like most recent values of that variable, was 3 degrees lower than normal.)
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.
