Weather report November 2017

There are a few minor changes to what went in the Gazette,

...  mainly a matter of me solving a computer problem.  The main issue was on the side of the keyboard away from the screen!
I do apologise to all chimpanzees, or indeed any life form more advanced than pond sludge, who wouldn't make a mistake as daft as the one I did!   Whatever, we're back on line!

Mainly a temperate month, with a very welcome serve of rain!

Rainfall

Yes, we got some!  At one stage it looked as though we might get over 100mm for the month but we 'only' got 76.4mm.  This is well above 2016 (and the average for the area since 1983) but slightly below the average of the last 10 years at our place.
 We are now well over 50% of the average rainfall , Year-to-Date.  Although I am very dubious about the statistical validity of projecting a 4th order polynomial with only 11 observations the value of R2 is pretty good.

Temperatures

At an early point in the month I commented that given the cold start, and low forecast temperatures we could be looking at the lowest average minimum ever for this month.  However some warmth arrived later in the month and we didn't achieve that.  Here are the daily extremes which clearly show the warming through the month..
 The next two charts show the average monthly value for maximum and minimum,  The maximum was still a little down ...
 ..  but the minimum, possibly due to the number of wet (or at least cloudy) days, was well up.
Obviously frosts were not an issue and we only had 2 days above 30oC compared to an average of 5 such days.

Humidity

The chart below shows relative humidity for 3pm in % and rain in mm.  They both (sort of) fit on the same axis.
 As would be expected, in most cases the higher humidity occurs on days on which it rained.  I was a tad surprised at the number of days (11) with rH below 40%.  To my surprise the average rH for the month at almost exactly 50% was greatly above both 2016 and the average of the previous 4 years.

Wind

A rather windy month overall (although calmer than August-September this year).
Most of the windy days were early in the month, and there is very little (r2 = 0.35) correlation between wind and rain!

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...
