“March 2016 like March 2015”
March raw anomaly data (orange)
In March 2016, raw values for nearly all measured climate anomalies moved close to normal. The exceptions were daily maximum temperature (x-axis), which remained very high as in February, and daily minimum temperature (lower left graph), which rose from very low to very high. Raw anomaly values for this month are similar to those of March 2015, a year ago. This is not evident on these graphs. As March 2015 came in a cool period, smoothed values of its temperatures are low. The original raw values are shown in the graphs for that earlier date.
Fully smoothed data (red)
The latest fully-smoothed data is for September 2015. Values were near normal and trending warmer and perhaps drier.
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.
