Trends to April 2016

April raw anomaly data (orange)

In April 2016, raw values for anomalies of daily maximum temperature (x-axis), daily minimum temperature (lower left graph), and daily temperature range (centre right graph) were high. Those of other variables were near normal, except that rainfall was rather low.

 Fully smoothed data (red)

The latest fully-smoothed data is for October 2015. Values were near normal. Temperatures trended warmer except in the subsoil, which trended cooler.


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.

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.
