You are looking fine, Charles. And your work is as always, interesting and delightful to the eye.
I have kept up with the Cyclone Debbie mess so been reading a lot about Australia, and finding exotic places on Google maps. The Whitsunday Coast is an amazingly beautiful place, hope it recovers fast.
And you are still in the Melbourne area?
Stay well my friend.

I want one of these Mobility Scooters

My knee surgery is complete, I am learning how to walk again, and could use a mobility scooter.    Like this one.

It is just a bit faster than the electric ones you see, this one can do a quarter mile and get to almost 108 miles per hour. (173 Kilometers/hour)  

Alas, I don't think my doc and PT will go for it.  And it really is a souped up go-cart with a motorcycle engine and a scooter frame, so I think Medicare might not pay for it.  Also kinda hard to use indoors.  But a man can dream.

According to Guinness World Record rules, to qualify the vehicle has to be based on a commercially available mobility aid and, from the outside, must look like a traditional motorscooter. So Anderson took a racing go-kart chassis, and re-designed it to fit the dimensions of a Days Strider mobility scooter. He then equipped it with the engine from a Suzuki 600 cc Bandit and replaced the 8-mph (13-km/h)-rated tires with racing wheels and tires from the go-kart.

Finally the Weather Shifts to Winter Rain in California

My favorite weather scientist +Daniel Swain has written a new blog post about the weather in California.  The short version, "Rainy Season is finally here in CA, some drought relief in sight"

Daniel states in his newest blog report:
There is very strong multi-model support for an extended period (of at least 3 weeks, starting on Sunday) of greatly enhanced storminess and widespread precipitation throughout California.
That is science speak for "It's gonna rain a lot for a while in CA." 

The large-scale atmospheric shift I’ve been referencing in nearly every blog post from the past 6 months has finally materialized, and will make itself known in California as early as this weekend.

This is the classic El Niño pattern that I have discussed in previous posts, with a powerful Pacific jet aimed either directly at or south of California.

The jet stream is dipping down enough for it to bring a long line of storms to California. That jet stream is shown below.

The area along of just north of the jet stream is a favorable position for storm development and intensification. Usually, California is located near the regional minimum of jet stream strength as it veers northward, but the imminent pattern shift will create a situation in which storms are much more likely to maintain their open-ocean strength or even strengthen as the approach California from the west. There is very strong multi-model support for an extended period (of at least 3 weeks, starting on Sunday) of greatly enhanced storminess and widespread precipitation throughout California.

EDIT
WeatherWest is read by many top climate scientists and weather experts, check out the extensive comments on this blog to get even more detail.  (for you real weather nerds)

Stay dry my California friends, have you cleaned out your gutters?

End of the Year Round Up

I have been bit busy with the holidays and our house remodel.  Thought I should check in with some pictures.  

There is a before and after of the solarium, and another before and after of the shower.  

I also included a picture of a Santa Sculpture that we have as part of our weird Santa collection, +Chad Haney should like this.   We call this Santa the 2nd Amendments Santa, he has his hunting rifle and a grim determined look. 

The last is a picture of an American Bushtit (no, not that kind, pervertシ) in our hedge.  They are tiny little birds and difficult to get a picture of as they are skittish and fast.  This is for a nature photo challenge that +Nikki C asked me to do months ago.  I think this is the number 4 of "nature" found in our yard.  Plus Nikki just posted that nice picture of an English Robin and she inspired me.

Terrible Fire in Massive Skyscraper in Dubai

I just saw this on Twitter.  Source is from Russia Today.

Pictures emerge on Twitter showing The Address Downtown Dubai hotel engulfed in flames. The building that hosts the 5-star hotel is 302 meters tall and is located not far from the New Year's Eve fireworks display.
It was not immediately clear what caused the fire, which covered at least 20 stories of the building near the Burj Khalifa, the world's tallest skyscraper, AP reports

Merry Christmas my Friends

I'm not religious, but for today I thought this post by +Don Komarechka was a good science/photography/symbolic one for Christmas Eve. 

Don is an amazing photographer of snowflakes, and he explains how these beautiful tiny crystals are formed as well as how he takes these amazing images.

So Merry Christmas to all and all a Good Night. 
Snowflake-a-Day #24
I’m not a religious person, but I thought this snowflake might be symbolic for many people. I saved it for Christmas Eve for that reason, but I’ll explain scientifically how these “crossed needles” form. View large!
 
 “Bullet rosette” type snowflakes like the one posted yesterday form in a similar way, but this is the “needle” variety. Needle crystals grow at slightly warmer temperature, only about 2 degrees below the freezing point of water. They form into elongated columns that grow much more rapidly, but they can also begin their lives around a common object with multiple nucleation sites.
 
Each crystal needs a nucleus to begin its growth. You can see a few new crystals forming from nucleation sites on top of the already-formed needed as well, two are easy to see where the needles cross. These could have been started from the impact of a super-cooled water droplet freezing on impact, giving rise to a new starting point. The same kind of origin is likely true for the initial needles that make up this snowflake.
 
Imagine a tiny pellet of ice, as if a small droplet of water has simply frozen solid. It wouldn’t be a crystal itself, but might have some irregular surface features for which water vapour could begin attaching itself to. This erratic start can cause crystals to begin forming at multiple points along the tiny ice pellet, growing independently of one another.
 
So, why the cross? Each crystal has the best chance of success if it grows into an open area where there is more water vapour to fuel further growth. The best-case scenario is seen when these crystals grow perpendicular to each-other, allowing for the maximum amount of space between the columns so that they do not inhibit the growth of one another. Other angles might be possible but by far the most common is this variety, as it has the greatest chance for outward growth.
 
This is similar to twelve-sided snowflakes, which are basically just two 6-sided crystals stuck together. They grow best when they’ve randomly stuck together in a 30-degree rotation, allowing each branch to have equal spacing on either side. Without equal spacing, twelve-sided snowflakes wouldn’t form and neither would crossed needles like this.
 
Needle-type crystals are very difficult to photograph because of the warm temperatures in which they form. The temperature in the clouds is often cooler than the temperature on the ground, and so close to the freezing point in the sky means they often begin melting before even hitting the ground. On rare occasions the ground temperature is equal or cooler than the environment where the crystal formed, and you have an opportunity to observe and photograph them before they disappear. There have only been two or three scenarios where I’ve been able to get solid needle images.
 
To understand how snowflakes form, and how to photograph them using the same techniques I use for all my snowflake photographs, pick up a copy of Sky Crystals: https://skycrystals.ca/book/ - it’s the best guide to photographing these beauties, and winter in North America is about to hit us in a few days! Temperatures are dropping, so get ready!

To see the fruits of my labour over five years and 2500 hours with the subject in a single image, check out “The Snowflake” print: https://skycrystals.ca/poster/ - nothing like this has ever been done before. It’s worth a look!
 
Merry Christmas!

Why Is the Sun's Atmosphere Hotter than Its Surface? 

Excellent post by +annarita ruberto. She is one of the exceptional science teachers that posts regularly here on G+.  (H/T to +Jyoti Q Dahiya)

The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the sun: What heats the atmosphere to such extreme temperatures?
Normally when you move away from a hot source the environment gets cooler, but some mechanism is clearly at work in the solar atmosphere, the corona, to bring the temperatures up so high.
Why Is the Sun's Atmosphere Hotter than Its Surface?

The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the sun: What heats the atmosphere to such extreme temperatures?
Normally when you move away from a hot source the environment gets cooler, but some mechanism is clearly at work in the solar atmosphere, the corona, to bring the temperatures up so high.

Clear evidence now suggests that the heating mechanism depends on regular, but intermittent explosive bursts of heat, rather than on continuous gradual heating. This solution to the coronal heating mystery was presented in a media briefing on April 28, 2015, at the Triennial Earth-Sun Summit, or TESS, meeting in Indianapolis, Indiana.

This is the inaugural meeting for TESS, which is a first of its kind: uniting the various research groups that study the sun-Earth connection from explosions on the sun to their effects near our home planet and all the way out to the edges of the solar system – a research field collectively known as heliophysics. The overarching goal is to share techniques across disciplines and encourage interdisciplinary collaboration on outstanding heliophysics questions.

The coronal heating mystery is one such outstanding question. Four scientists spoke at the media briefing.

Jim Klimchuk, a solar scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, explained that the new evidence supports a theory that the sun's corona is heated by tiny explosions called nanoflares. These are impulsive heating bursts that individually reach incredibly hot temperatures of some 10 million Kelvins or 18 million degrees Fahrenheit – even greater than the average temperature of the corona – and provide heat to the atmosphere. The research evidence presented by the panel spotted this super hot solar material, called plasma, representative of a nanoflare.

"The explosions are called nanoflares because they have one-billionth the energy of a regular flare," said Klimchuk. "Despite being tiny by solar standards, each packs the wallop of a 10 megaton hydrogen bomb. Millions of them are going off every second across the sun, and collectively they heat the corona."

Image Description: NASA's EUNIS sounding rocket examined light from the sun in the area shown by the white line (imposed over an image of the sun from NASA's Solar Dynamics Observatory) then separated the light into various wavelengths (as shown in the lined images – spectra – on the right and left) to identify the temperature of material observed on the sun. The spectra provided evidence to explain why the sun's atmosphere is so much hotter than its surface.
