Longer November heatwave 130 years ago

By Brett Dutschke
Weatherzone, November 24, 2009

The most recent heatwave was record-breaking for many areas, but in November 1878 a heatwave lasted almost twice as long, according to weatherzone.com.au.

Nearly all inland areas of New South Wales and South Australia and surrounding areas of Victoria, Queensland and the Northern Territory have had at least eight days of extreme heat, record-breaking for November.

But in some inland towns, records were not broken.

Inland weather stations which have measured temperature for the last 131 years or longer show that there was a November heatwave which lasted about two weeks.

Gunnedah, in northern NSW had 15 consecutive days of 35 degrees or hotter in November 1878. This month Gunnedah had nine in a row, the longest November stretch in 131 years. The northern NSW town only averages four-to-five days above 35 in November.

With this piece of evidence one could claim that this most recent hot spell is unprecedented in November in 131 years.

For some coastal areas of South Australia, including Adelaide this year’s heatwave is the longest on record for November. Official temperatures have been measured as far back as 1887 in Adelaide, but not as far back as 1878, like Gunnedah.

Dear Editor,

In answer to this question the “100” year cycle has hit. The year 1879 came at the end of five warm sunspot cycles before entering a period of milder cooler cycles from 1878 to 1933. This weather action is falling in at the end of seven very warm sunspot cycles from 1934 to 2007.

Some trigger action is in place that causes this to show up when transitioning from a global warming period to a global cooling period. A meteorologist would have to find and explain the trigger.

We have entered into a solar minimum that hits every 100 years for two cycles per Joseph D’Aleo. The next two cycles are going to be more characteristic of the 1700 to 1723 and 1798 to 1823 cycles.

We are in for very cold weather, drought and very low lake levels for the next 20 to 30 years, roughly.

My work is posted at nationalforestlawblog.com October Newsletter above Al Gore’s picture.

Most Sincerely,

Paul Pierett
