May Climate Anomalies Log

Heat Indicators log for May months

This post is the third in a set for the 12 calendar months. Graphs are sixteen-year logs of the monthly mean anomaly values of nine climate variables for Manilla, NSW, with fitted trend lines. I have explained the method in notes at the foot of the page.

Raw anomaly values for May

Extreme values of May anomalies in this period were:
Daily Minimum Temperature anomaly -3.6 deg: May 2006;
Morning Dew Point Anomaly +3.6 deg: May 1999;
Morning Dew Point Anomaly -3.9 deg: May 2006;
Morning Dew Point Anomaly -3.2 deg: May 2011;
Morning Dew Point Anomaly -4.4 deg: May 2012;
Temperature range anomaly (minus) -3.2 deg: May 2006.

Trend lines for May

Heat Indicators

The trends of all three air temperature anomalies were almost the same, except that anomalies of daily minimum temperature were more negative. All began high in 1999, reached a minimum in 2002, a maximum in 2007, and a minimum in 2011-12. The trend of subsoil temperature was contrary, and generally increasing.

April Climate Anomalies Log

Heat Indicators log for April months

This post is the second in a set for the 12 calendar months. Graphs are sixteen-year logs of the monthly mean anomaly values of nine climate variables for Manilla, NSW, with fitted trend lines. I have explained the method in notes at the foot of the page.

Raw anomaly values for April

April anomalies had few extreme values in this period:
Daily Maximum Temperature anomaly +3.4°: April 2005;
Morning Dew Point Anomaly -3.3°: April 2008;
Morning Dew Point Anomaly -4.8°: April 2013;
Rainfall anomaly +79 mm: April 2003.

Trend lines for April

Heat Indicators

The trends of all three air temperature anomalies were almost the same. They began very low in 1999, reached a maximum in 2002-3 and a minimum in 2009-10. The trend of subsoil temperature began similarly, but with much less variation, and peaked in 2012.

March Climate Anomalies Log

Heat Indicators log for March months

This post is the first in a set for the 12 calendar months. Graphs are sixteen-year logs of the monthly mean anomaly values of nine climate variables for Manilla, NSW, with fitted trend lines. I have explained the method in notes at the foot of the page.

Raw anomaly values for March

Extreme values for March anomalies in this period were:
Daily Minimum Temperature anomaly -2.9°: March 2008;
Morning Dew Point Anomaly +3.5°: March 2000;
Morning Dew Point Anomaly -3.2°: March 2008;
Rainfall anomaly +61 mm: March 2007;
Percent cloudy mornings anomaly +37%: March 2011.

Trend lines for March

Heat Indicators

Daily maximum temperature showed minima about -1 deg in 2001 and 2014, and a maximum about zero in 2007.
Daily minimum showed a minimum two years later, about 2003, then rose in parallel with daily maximum, but ended very high.
Subsoil temperature did not agree, and varied less. It had maxima in 2002 and 2012. It may show a lag of five years behind daily maximum.
