“Sunny return from “flooding rains””Trends to April 2011

Most of the April 2011 raw data values (in orange), other than daily maximum temperature, are now on the “droughts” side of normal rather than the “flooding rains” side, which had dominated for about a year.

Smoothed October values include new 12-year record anomalies for daily maximum temperature (low) and cloudy days (high).

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.

“Extreme cloudiness”Trends to March 2011.

Most of the March 2011 raw data values (in orange) are nearer to normal than to recent extremes. As an exception, the March cloudiness anomaly is a record +37%: there were 19 cloudy mornings instead of 8.

Smoothed September values include new 12-year record anomalies for daily maximum temperature (low), cloudy days (high) and daily temperature range (low).

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.

“Sudden Rise in Temperatures”Trends to February 2011.

In the current plots we see final smoothed trends for the winter (JJA) of 2010.

Daily Maximum Temperature

On each plot, the x-axis has the anomaly of mean daily maximum temperature.  In winter 2010 the smoothed temperature anomaly fell very rapidly to near the earlier record low smoothed value. Partially smoothed later values suggest that an extreme negative temperature anomaly came in November 2010. The raw value for February 2011 is remarkably high.

Rainfall

Rainfall anomalies are plotted (inverted) on the y-axis of the first graph. Fully-smoothed winter values were all positive, rising with falling maximum temperature. Later values generally rose rapidly to an apparent positive extreme in November.

Cloudiness

During winter of 2010 the anomaly of percent cloudy days rose to yet a new record for fully-smoothed values. It continued to rise to an apparent extreme in October 2010, since when it has remained extremely high.

Early morning Dew Point

The Dew Point anomaly was positive and rapidly rising in winter. It seems to have peaked at less than a record value in October 2010. By February the anomaly was much less positive.

Daily Temperature Range

The temperature range anomaly fell during winter to yet a new negative record for smoothed data. It continued to fall to an apparent negative peak in October 2010. The raw value for February and the little-smoothed value for January are right back near normal.

Daily minimum temperature

Winter daily minimum anomalies remained little below the peak of December 2009. Later values traced an arc through the “Equable” zone of the graph, until February’s raw value was again near the December 2009 peak (“Hot Days; Hot Nights”).

Subsoil temperature

The winter subsoil temperature anomaly was below zero and falling quite rapidly. It then accelerated downwards to an apparent negative extreme in November 2010. By February, the raw value was back higher than any point on the 3-year trace.

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.

“”Flooding Rains” stop”Trends to January 2011.

The raw January 2011 anomaly values have leapt away from the “Flooding Rains” area in the bottom left corner of the graphs. Anomaly values of maximum temperature and temperature range are up, and that of rainfall is down.

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.

Trends to November 2010

Data points for climate anomalies in the autumn months (MAM) of 2010 are now fully smoothed.

  • In autumn 2010 the smoothed maximum temperature anomaly fell much faster than it had risen in the previous autumn (clearer on the second and fourth graphs). Partially smoothed later values suggest that an extreme negative temperature anomaly came in October 2010.
  • Rainfall anomalies are plotted (inverted) on the y-axis of the first graph. Fully-smoothed autumn values rose with falling maximum temperature, but remained negative. Later values generally rose rapidly to an extreme positive raw value of +38 mm in November.
  • During autumn of 2010 the anomaly of percent cloudy days rose to a new record for fully-smoothed values. It continued to rise to an apparent extreme in October 2010.
  • Early morning dew point was positive and rising in autumn. It seems to have peaked at less than a record value in September 2010.
  • The anomaly of daily temperature range fell during autumn to a new negative record for smoothed data. It continued to fall to an apparent negative peak in September 2010.
  • In autumn daily minimum anomalies fell little below the peak of December 2009. Later they traced an arc through the “Equable” zone of the graph, ending near zero.
  • The autumn subsoil temperature anomaly was near zero and scarcely falling. It then accelerated downwards to an apparent extreme in October 2010.
