#365daysofbiking Inverted

Wednesday November 25th 2020 – I took to the canal towpath on the way home which was a bit of a mistake as it had rained a fair bit in the morning, and the way was lined with muddy puddles that made for damp legs.

But there was a treat waiting.

As I travelled, my headlight started picking up swirls of mist over the water, and by the time I was near the new pond and Clayhanger Bridge, there were appreciable clouds of vapour rising and tumbling above the water, but only in short stretches, whereas others were clear.

This phenomena is a meteorological inversion and is absolutely captivating to watch.

The bike headlight did a great job of lighting the scene up. It really was gorgeous. Best I’ve seen for a few years.

March 4th – The thing about an inversion is it’s transient. This one came and went in about 15 minutes, and it’s ever changing. As it drifted away, it left clear skies, a very noisy gull roost and beautiful colour.

Even the coos looked impressive with their clouds of steam

That’s how you fix a bad mood, and that is exactly why I ride a bike.

March 4th – I was going stir crazy. A bad day – the internet was getting me down, the thaw had set in and the world outside had the slimy, grey, filthy wet feel you only get with melting, heavy snow.

I slipped out on an errand at sunset and something magical happened. I caught a surface-air temperature inversion. I saw it start on The Parade in Brownhills, as it was gathering over the common. I raced to Chasewater. It was stunning.

An inversion occurs when the ground is colder than the air above and mist forms is very low, isolated pockets. I’ve not seen on this strong since I was a kid. Mist drifted around and almost deserted Chasewater, and I was in the middle of it, like a kid in a sweet shop.

January 13th – Now, this is winter at last. Riding homeward at 6pm, the air temperature according to the ride computer was -2.4 degrees C. It felt it too.

That morning had shown a light, wet dusting of snow, and it half-heartedly snowed during the late evening, too.

I’d like a bit of snow, or some good hard frosts.Come on then, weather… show us what you’re made of.

March 18th -This week has odd weather. Misty, with a perceptible wind, but the air quality is very poor; it seems smoggy like it did about a year ago, but I could be imagining that. The sun seems to have a hard time penetrating the murkiness, but when it does, it’s springlike, and warm.

It makes for decent canal views, that’s for sure.

April 3rd – The poor air quality brouhaha at the moment isn’t all hype. As a chap given to a degree of sinus trouble, it’s hell out there at the moment. There’s an appreciable wind, and the air isn’t wet like in normal mist; yet it feels oxygen-less, like being stuck in an unventilated house with the heating on. It makes me feel breathless faster, and stings my eyes, as well as causing a blocked nose. 

I’ve never experienced days like these before. I’m used to traffic fumes in the city in high summer, and the effect it has on my hayfever, but I’ve never seen this before.

The New Ring Road in Walsall looked ethereal and grey, even dystopian. But I did notice one thing; that’s a fine weathervane on the roof of the old Workhouse Guardians office, there.

March 27th – Not a great photo, but the light was terrible as I headed home. This curious matt-brown box with a bright white light on top puzzles many folk heading east towards Chuckery on the New Ring Road in Walsall, just by Queen Mary’s School. It’s an environmental monitoring pod which takes climatic and and air quality measurements, and logs them. It features a host of sensors – the white light is a particulate analyser, shining light through the air and measuring the floating contaminants. There will be wind, temperature, humidity, and various chemical sensors humming away in what is actually a vehicle trailer. The triangular cowl on the front is covering the towing hitch.

This is a fairly expensive piece of kit, being used to tell us what anyone in Walsall already knows; the air quality here is terrible – particularly next to a badly designed junction where traffic is often static.

No shit, Sherlock.
