July: warm and humid

July raw anomaly data (orange)

Temperatures

Daily maximum temperature anomaly (all x-axes), remained near +1 deg.
Daily minimum temperature anomaly (lower left): rose very high (+2.5 deg).
Subsoil temperature anomaly (lower right): remained very high.

Moistures (moist is at the bottom)

Rainfall anomaly (upper left) just below normal.
Cloudiness anomaly (upper right): near normal.
Dew point anomaly (middle left): just above normal.
Daily temperature range anomaly (middle right) low (humid).

 Fully smoothed data values (red) 

Fully-smoothed data for January 2020 shows that the daily maximum temperature anomaly continued to fall from the record value of October 2019. The daily minimum and subsoil values were static.
All the moisture indicators (rainfall, cloud, dew point, and daily temperature range) continued to move downward, showing decreasing drought.

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.
