Weather July 2016

Sorry this is a bit late: I have been finding (mainly) better weather elsewhere.  The following table gives the report in Gazette format - a bit different to that which appeared in hard copy as it now shows what my weather station recorded at home, rather than details for another site which I was able to access over the internet from Atherton!

In summary July seems to have been a pretty good month to be away: wet cool and windy.

Rain
Another above average month, although not so much as June.
This next chart shows the daily falls.

 Falls greater than 0.5mm (to get away from decent fog being recorded as 0.2mm) occurred on 12 days.  Looking back at history (since 1993), for July the average is falls of this level being recorded on 8 days and only 1995 recorded more wet days at 15.  By the end of the month we were 47mm in front of last year.

Temperatures

The next chart shows daily maxima and minima and change over the day.

Basically a couple of cool spells followed by warm damp times.  Looking at comparisons with longer term averages:

The average maximum was a tad above the long term average but, as with June 2016 the average minimum was very much above average at positive 1.5oC  rather than negative 1.3oC.  

 This led me to lok at the number of frosts recorded this year.   Minima below 0oC (air frost) were recorded on 12 days and below +2oC (ground frost)  on 18 days.  While this seems pretty chilly, both values are well below the average.  The next chart shows the number of frost days recorded each month thus far in 2016 as a percentage of the average number of such days by month.
Clearly it has been a much less frosty Autumn/Winter than average.  This is probably due to it being so damp.

Humidity

As usual I have used the 3pm (1500hrs) value.
Humidity at 1500hrs didn't drop below 50% at any point in the month.  This emphasises the the cooler months of Winter achieve higher humidity levels than Summer but the average outcome for the month is only slightly above the long term average.

Wind

Basically a rather blowy month.  The maximum gust each day ...

... while looking like a cross section of the Alps, shows a draughtier picture than usual.  This is emphasised by a comparison with longer term averages.

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 our routes: That map comes from Google Maps (G

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 recall years ago driving al

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 birds: The view from the top of
