The snow in Stockholm is melting and partly turning to ice.

Seriously, you wear shoes like that under those conditions you deserve to be on the ground! At least here in Colorado we know how to dress for the weather.

Yesterday, there was a 45°C difference between the warmest and the coldest places in Canada. But change is coming later this week as an arctic blast slides south across the prairies to cover most of the country, in fact much of the continent. (It's coming to get you Chris.) We'll miss the worst of it here on the east coast, but we'll certainly lose our above seasonal weather. It'll soon be time to hibernate.

Excellent! I'm looking forward to it.

Well... the icy cold weather disappeared, and we got this instead.

The American song, "Try to Remember the Kind of September" was translated into Swedish as "Minns i november den ljuva september", "Remember in November the lovely September". The latter message seems particularly particularly apt right now.

Halifax also looked like that late yesterday afternoon and into the evening. But it had begun to rain by the time I got up this morning, and the rain washed away the fog.

Cold leads to interesting structure when you start with a lattice.

Swimming in January in Öresund.
Photo: SVT.
Today was very cold here in Malmö, −12oC in the morning. But some people like to swim when it's cold. At the beach of Ribersborg, along the Strait of Öresund, we have something called a "cold bathhouse" - a building with a sauna and a bridge with ladders leading down to the waters of Öresund. In the winter, you can bet the water is cold. But some people love to sit in the sauna and get blisteringly hot, then get down into the ice cold water, then return to the sauna, then get down into the water again, and so on. Some people will do that for an hour or more.

Here is a link to a video, unfortunately in Swedish, where you can see two naked men brave the icy water of the Strait of Öresund. They are smiling and looking happy, and after their dreadfully cold bath they are sitting all naked on the bridge, sunning themselves in the bitter cold. It's worth seeing!

Tomorrow we will have snow. I hate it!

Our high yesterday was -18°C! We got about 6" of fluffy snow. It dipped to -23°C around sunrise this morning, but it's totally sunny today and up to a balmy -10°C- didn't need more than a flannel shirt to be out shoveling snow. Supposed to be back up above freezing for the next week or more. And sunny, of course.

But some people like to swim when it's cold.

I like cold weather. But I like being warm in cold weather. I'll pass on swimming!

The deck thermometer when I got up this morning. That's Fahrenheit.

If ice somehow locked the needle in place, would the thermometer lose calibration?

I don't think so. The mechanism is some kind of bimetal coiled spring, so if you lock the needle, there's just an increasing torque as the temperature changes- not enough, I think, for the pointer to slip on its axle. At least, it's lived through about 15 winters on the deck, sometimes under snow or with ice on it, and I've never fiddled with the calibration.

Keeping the driveway clear gave us the chance to check out the angle of repose for dry snow while Bo watched from his own repose. :ssmile:

IMG_8256.JPG

At 2600 feet a dry snow is unusual here. Back in the distance I'm sure night skiing was excellent at Bogus Basin's 7600 feet. After finishing we stuck to breaking out the thirty year old cross country skis. :yes:

Dry snow, eh? We don't get that here. Our snow is almost always wet and unpleasant. Like now. :x

The angle of repose of dry snow? Yours looks impressive, I'll grant you that! :shock:

We've just had the first real day of spring here in Malmö!

Winter aconite in the Old Churchyard in Malmö.

People have been out strolling about, or sitting down wherever they could sit to soak up the sun. Kids have been playing in ponds, jumping about on rocks sticking up out of the water and playing with sticks. Many parks are absolutely yellow from winter aconite.

I've seen the first specimens of tussilago farfara this year, and tiny mosquitoes swarming around them. I've also seen sweet-smelling Viburnum farreri, iris, scilla, and many different kinds of crocuses.

The blue tit, Parus Caeruleus, was singing loudly.

It was a lovely day! :D

Malmö welcomes spring with a dance!

Oh well. Tonight we're going to have snow. But we won't get as much snow as they did on the U.S east coast a couple of days ago.

I found this video on youtube, and I can't resist it. Lot's of fluffy snow, big train, powerful snowplow, and people waiting for the train on a platform.

It really is springtime in the Rockies! It came early this year, with some flowers nearly a month early and aspen leaves at least two weeks early. Last week we had a couple of nights way below freezing, but luckily they didn't seem to damage the early growth. Snow on Thursday and Friday, but temperatures above freezing. Went riding on Saturday, through snow and new spring leaves, sunny and well above freezing.

IMG_2839p.jpg

Woke up this morning to over an inch of wet snow, but still above freezing. Took this from the deck. Loving all this moisture; it's what will make for a green summer with lots of wildflowers.

Science@NASA: Greenland's Thinning Ice

Postby bystander » Mon Jun 12, 2017 3:14 pm

Greenland's Thinning Ice
ScienceCasts | NASA Science News | 2017 Jun 08

Click to play embedded YouTube video.
With temperatures around the world climbing, melt waters from the continental ice sheets of Greenland and Antarctica are raising sea levels. Those ice sheets are melting from both above and below. Much of the ice lost from ice sheets comes from a process called calving where ice erodes, breaks off, and flows rapidly into the ocean. A large volume of ice is also lost from ice sheets melting on their surfaces.

To determine to what extent Greenland’s glaciers are being melted from underneath, NASA recently began a 5-year airborne and ship-based mission called Oceans Melting Greenland (OMG).

Previous research has shown that Greenland's glaciers, which flow like rivers of ice into the ocean, sit on the ground deeper below sea level than had been thought. Warm ocean currents sweep across and erode the hidden glacier faces. As a result, they’re melting faster – a few feet a day in summer – than anyone suspected. ...

For this study, a NASA aircraft is flying the Glacier and Ice Surface Topography Interferometer (GLISTIN) instrument around Greenland for a few weeks each year. ...

While OMG is looking at the effects on ice sheets from below, NASA’s Operation IceBridge mission is surveying polar ice from above. The overlap of OMG and IceBridge is providing the most accurate measurements to date of changes in Greenland’s ice sheet mass. ...
Know the quiet place within your heart and touch the rainbow of possibility; be
alive to the gentle breeze of communication, and please stop being such a jerk.
— Garrison Keillor
