October weather report

Rainfall

We did fairly well for rain this month, with 55.2mm:
  • exceeding my 'tolerable' benchmark of 50mm;
  • beating last year by 41.5mm; and
  • only being 0.6mm below the 7 year average
We also scored non-trivial rain on 5 days, spread through the month.  

Taking a slightly longer term squizz at this, my 12 month moving average appears to be taking a small up-tick after a rather dry Winter.

Temperatures

Overall quite a pleasant month with warming daytime temperatures and cooling at night.  The 14th was an exception with next to no range of temperature and a maximum of 7!  Hello mid-Winter!

In terms of my seasonality comments in the September report this month neither achieved a high of 30oC nor achieved >50% of days with an air frost (although we did get 3 of them to punish early tomato planters).  So it fits nicely in my bracket between Winter and Summer (ie Spring).

Humidity

The humidity values for the month were all over the place, with particular peaks on the rainy days.
The very low values towards the end of the month made me wonder how it fitted in to an annual pattern.The answer is "pretty well",   That is especially since I have shown only a basic parabola as my trend getting an R2 of 0.89: upping the order of the polynomial to 4 gets us to an R2>98% (but is probably pushing degrees of freedom constraints a tad)!

Wind

Again the chart does a good impersonation of a cross cut saw.  I looked at the monthly averages (using various measures of amount of breeze) and they showed nothing of significant variation.  More data is needed, and time is the only healer of that problem.

Insects from pine trees

Image
This afternoon (13/1/2015) we were looking out of our sunroom and noticed a strange bit of mist.  On getting my binoculars on the case I found it to be a cloud of tens of thousand of insects.  They appeared with naked eye to be flying away, but with binoculars I thought they were circling. Here are some images In the second one it may be possible to see there are two streams coming from the top of each tree. There was a loud buzzing noise but that could just be several thousand wings. Earlier in the day Frances had been to some nearby willows and they were infested with many little black soft bodied insects.  Perhaps they shifted to the pines and were swarming? Help!! Any information welcome. A colleague, from Wamboin, had noticed a similat phenomenon, but involvng eucalypts rather than pines!  Here are the photos he took with his phone. I have consulted some expert friends.   Their responses were: I would have gone for chironomids. I rec...

A tour of the West (part 1)

Image
A friend from my time in the UN sent me some photos of her family trip along Route 66.  They did this is a large camperwagon rather than a Chevy Corvette (apparently the kids jacked up about being offered a trip in the trunk).  It seems to have been a very good trip for them and most interesting to see their photos.  It was also educational for me, as I found out the German for rocking chair (schaukelstuhl, since you ask). They did 7200 miles in 30 days - a pretty serious bit of distance. This made me think of the trips we did in 1981 when living in Denver.  Frances initiated that idea by getting a book about the National Parks of the West  and marking interesting places.  I then worked out a route on a Rand-McNally Road Atlas (GPS was unknown then  - as were iPhones, personal computers and the internet).  From memory, taking nearly the whole Summer school holidays we covered about 10,000 miles in 70 days.  Here, approximately,  are ...

Maslins beach rules

Image
Anyone who was in Adelaide in the 1970s will be having a good nudge nudge at that title.  However the beach is really nice even though it is the haunt (in Summer ) of naked people.  (As an aside one of the 'van park staff was talking to some other guests and commented that the sights on the beach in Summer were not at all exciting.)  In April it is the haunt of seniors, many of them exercising their dogs, and thus a far more attractive place. Getting to the beach was a walk of about 1km along roads, from our van.  The second half of this went past a rather daggy looking paddock with many formed ridges in it, as though it was irrigated, although a water sources wasn't evident.  The paddock got interesting towards the end as some green parrots appeared.  Thanks to Frances eye for detail we have subsequently identified these as Elegant Parrots: my first lifer for 2014.    The locale is indicated by the red lines in this mudmap: Here are the bird...
