August 2015 weather

In official terms August is the 3rd month of Winter.  According to the Canberra Times it was a very cold and wet three months. I'll start with a few images that seem to support that view.

Verga on 24 August, looking to the East from the top of the block during our morning walk.

The 25th of August was seriously unpleasant weather.  Cool, cloudy, showers and wind.  Here are a couple of radar images.  First a Doppler wind image: the dark streaks to the West of Carwoola suggest the wind is gusting at over 100kph on the western side of the ranges.
We only scored 3.4mm of rain that day but the image below shows it bucketing down towards the coast.  The yellow patch was there most of the day.

Rain (or rather Precipitation)

I have suggested precipitation as a heading as we got snow on 12 August.  By 1315 that was well into settling and the temperature had dropped to 1.1oC!  The passage of that event is shown best by a temperature chart.

Here is the overall comment on precipitation.
We ended up with our highest ever August rainfall of 76mm.  That is the third month this year in which have set new records.  here were significant falls on 4 days, spread through the month (mainly on Wednesdays to muck up the ANPS WWs).

Temperature

 The bottom of the green lines shows the minima and they are steadily below freezing apart from the very warm patch 22 to 26 August.

We had 6 days with a maximum below 10oC, the lowest at 6.9oC.  3 days staggered through 15oC on one occasion reaching the giddy heights of 19oC.  The average maximum temperature was a little lower than the 3 years average.
There were 20 frosts with 19 of them being below 0oC.  In contrast there were 5 days in the "warm patch" referred to above where the minimum exceeded 5oC.  This had the effect of boosting the average minimum (just) into positive territory.

Humidity

Quite a moist month.
Taking a longer view, it was above the three year average value but slightly less than the other two months of Winter,

Wind

The month was a fair bit draughtier than other recent months with an average gust of 7.24 kph.  However this is probably just getting back to the "normal' values.

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...
