3-year trends to November 2011

“Bizarre values of climate anomalies”Trends to November 2011.

Most raw values for variables for November 2011 are bizarre. The rainfall anomaly (top left) is so high the scale has had to be extended by four times. The daily maximum temperature anomaly (all graphs, x-axis) has jumped from very low to high. High temperature seldom occurs with high rainfall, but that is thought to be normal in an interglacial climate. Similarly for the high Dew Point (centre left) with high maximum temperature. Two other temperatures jumped up along with maximum temperature: minimum temperature, and subsoil temperature.

Fully-smoothed data points (red) are now available for the autumn months (MAM) of 2011. Each variable showed a steady trend in one direction (but this did not continue through winter).
Max temp increased towards normal.
Rainfall decreased through normal.
Cloudiness was high but decreasing.
Dew Point (humidity) was below normal and falling very rapidly.
Temperature Range was rising towards normal.
Min temp was falling through normal as max temp was rising: a trend from equable towards extreme.
Subsoil temperature increased with maximum temperature.

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.
