November just like October

November raw anomaly data (orange)

Temperatures

Daily maximum temperature anomaly (all x-axes): now three degrees above normal.
Daily minimum temperature anomaly (lower left): remains high.
Subsoil temperature anomaly (lower right): still near normal.

Moistures (moist is at the bottom)

Rainfall anomaly (upper left): still very low.
Cloudiness anomaly (upper right): still normal.
Dew point anomaly (middle left): still rather low.
Daily temperature range anomaly (middle right): has risen back to high.

 Latest fully smoothed data (red) includes autumn 2019

Smoothed anomaly values are now available for the autumn (MAM) of 2019. Generally they show a steady retreat from the extreme (smoothed) anomaly values of January. Rainfall anomaly rose, while daily maximum temperature anomaly fell. Daily minimum temperature anomaly fell rapidly, and subsoil temperature anomaly rose rapidly. Cloudiness and dew point changed little. Temperature range anomaly, which had decreased slowly to January, began to increase again.

Notes:

January data points are marked by squares.

Smoothing

Smoothing uses Gaussian functions.
For fully smoothed data the function has a Standard Deviation of 2.5 months, it spans 13 monthly data points, and has a half-width of 6 months, which suppresses cycles shorter than 12 months. For partly smoothed data, the span of the function is reduced to 11 months, 9 months and so on.

Fully smoothed data points are plotted in red, partly smoothed data uncoloured, and raw data for the last data point in orange.

Limiting values

Blue diamonds and the dashed blue rectangle show the extreme values in the fully smoothed data record since September 1999.

Normal values

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.
