Mountain Weather : Inversion Layers

Temperature inversion layer above Fairfield taken from from St. Sunday Crag. This climate phenomenon is due to a layer of warmer air above the cold dense air mass closer to the ground. I believe that the principle reason for this formation is due to a combination of the high pressure air mass which was sat on top of the UK and the low angle of the winter sun. According to Wikipedia "An inversion is also produced whenever radiation from the surface of the earth is less than the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the angle of the sun is very low in the sky."

Conditions in the higher layer were extremely bright clear air with temperatures around freezing, maybe +1° Celsius. Visibility was in excess of 20 miles despite the haze and the wind was steady around 20 mph. Within the lower layer the temperature must have been closer to -8° Celsius and the wind significantly stronger and the humidity; judging by what most people call hoar frost, but is in fact advection frost, which formed on everything and every one; close to 100%. The visibility within the colder layer was down at around 15m and the transition between one layer and the next was very sudden, within around 20m.

There seems also to be some particular aspects of this specific fell and it's surroundings that makes this dramatic formation occur regularly. I have seen and photographed it before on several occasions over the years.

High Up Iced Up

The Deepdale Horseshoe

Endorphins free flowing a day set up with great promise the weather forcast looked amazing with the high pressure still maintaining a presence over the UK after several days. This High was the cause of the bright clear weather last Saturday and the fantastic clear views from Place Fell and the still cold air in the valleys. Arriving in Patterdale at around nine am the outside temperature, according to the car's computer, was -6°C and everything was white and icy.

A burst of activity and the steep slope up to the 1st shoulder of St. Sunday Crag is reached; the views into the eastern crags of Helvellyn group is fantastic, it's so clear and you can see for miles, except the for the haze. The view over Ulswater is worth the climb in itself. I just manage to capture the steamer on its way across the lake, it's wake making increasing patterns on the surface.

The cloud which is streaming over Fairfield is being held at bay by the mass of relativley warm high pressure air sat on top of the colder layer below.

This inversion layer looks dramatic with freezing fog/cloud billowing in the strong wind, seemingly following the contours of the fell as it over Fairfield, Cofa Pike and down into the hollow at Grisdale Tarn. Eventually it seems to escape and breaks out over Dollywaggon and Nethermost Pike.

The route I plan to take takes me right into the cloud layer as I climb steeply up over Cofa Pike and on to Fairfield. As I pass those coming down everyone mutters something about how cold it is and judging by their appearance, they're all covered in a white frost they are not joking.

The temperature gradient is dramatic as is the change in visibility. From a almost warm 0°C in the sunshine on St Sunday to what feels like -8° takes almost no time at all and by the time I get to the top of Cofa Pike the visibility has dropped to just a few metres.

Inversion Layer

Navigation on the summit of Fairfield is notoriously difficult, the place is flat and relatively featureless. Even the cairns only add to the confusion in the fog as they are too close together and too many in number. Several times along the path to Hart Crag, the point at which I turn left to follow the path down to Bridgend, I'm asked for directions or confirmation of where we are. At one point I get the GPS and the compass out to make doubly sure as a small group of walkers, obviously on some form of organised walk are completely disorientated.

The remainder of the route follows the ridge down from Heart Crag over Black Crag and Hartsop Above How and the transition from the cold inversion layer back into the warmer one is almost as dramatic.

Boxing Day

Boxing Day is a no running day, given the profile of the Horsley Hell Run this must constitute a "Bank Holiday"

Xmas is Postponed

As Christmas is Postponed this year until Sunday runnin seemed to be in order. Another review of the Training Extended run, this time taking in the track beside Whittle Dean and through the village at Ovingham without having to run on the road. While I didn't have the GPS analysis of the map would put the total at 5 miles in just under the hour. Big mistake this time was not taking water or other fluids, suffering from cramp in the shins as I ran up the bank back to Horsley (HHR).

A Walk on the Wild Side

Dunstanburgh Castle

A walk along the Northumberland coast from Howick Haven to Low Newton

Sky flat calm sea
Castles in the sand
Light reflecting on air
Clouds standing waves
Views that seem to go on for ever
Along the edge
Where land meets sea and sky
Walking, talking
Feasted on crab, coffee and beer
Then turning for home
Chasing down the sun on the shortest day
Just time enough to see

The Icy Adventures of Gripp Type-Thinne

Catstycam and Red Tarn

With apologies to Spike Milligan and the Goons

On arrival in Patterdale, somewhat later than planned, our hero Gripp stares alternately into the back of the car and upwards to the fell tops and the sky. He's thinking of the weather, the distance and the snow and icy conditions.

He's troubled, there are three pairs of boots in the car; the new inov-8 trail running shoes untested in the snow; the old and trusted Scarpa Manta mountaineering boots and the cheap and bendy lightweight boots he's been wearing all summer and to which he has a fondness that apparently outweighs reason and experience. True since wearing these boots he's not had blisters and that is something of a miracle for he as been troubled with the ragged and bleeding heels affliction constantly through out his walking life and there are distressing visuals to prove it. He forgets though that the adoption of the 1000 Mile socks may also have something to do with it too.

He recalls the previous outings using the Scarpa's with dread, all he remembers is pain and suffering all the way up and down the fell. He forgets also the fact that this was before he got himself fit and 2st lighter and was, at that time, unable to walk more than 100 or so yards up an incline without getting out of breath. He makes his decision, wear the bendy boots, take the short ice axe and we'll be OK, it can't be that bad! can it?

Striding Edge

An hour and a half later just at the start of Striding edge proper Gripp was beginning to see the error of his ways and the lack of forethought in his decision. A slight panic was developing in his lower organs and the iPod was switched off to help his concentration, he needed all his experience and skills to be focussed on the snowy ridge in front of him.

He could of course have done the sensible thing, go back down to the pub but that would have been defeatist and cowardly, at least in his mind. The staff from Patterdale Mountain Rescue would not have thought so and the newspapers would not have their story if he had. You know the kind of thing Reckless Walker Endangers Life and Costs mount as Helicopter Rescue is launched blah blah. BBC News / Cumbria

He presses on, at first the broad expanse of the ridge is easy and the Névé is almost perfect. But as the ridge narrows and funnels him onto the crest of the ridge the ice is showing through and the rocks are covered with verglas, with zero grip from the bendy boots,` balance is all that keeps our hero upright and moving forward rather than accelerating vertically downward.

The ridge narrows even further and Gripp has to resort to the old fashioned approach, a cheval which brings new meaning to a shiver in his nether regions. There several points on the route now that demand all the concentration he can muster and others on the same journey gasp in astonishment, not as our hero imagines at the skill and bravery but at the foolishness of his escapades.

As the ridge abuts the fell proper there is a steepening of route which is banked nearly to the vertical with hard snow and ice. With bendy boots it's impossible to kick steps in the frozen water and Gripp has to rely on climbing what rock remains sticking out of the snow and using steps kicked by others or resorting to an ancient and almost forgotten skill of step cutting. Twice the second hand steps give way and sliding backwards the ice axe is brought into play. At least he had the sense to bring that.

Then almost suddenly the terrain flattens out onto the summit plateau and the stone cross near the actual summit of Helvellyn, euphemistically referred to as a shelter,is reached. Gripp sits down with some relief and refuels with coffee and favourite hill food

Micro-blogging using the Nokia E61 phone is not always as easy as one would like. The lack of signal lower down the fell and indeed in Patterdale itself, means that on this walk I'd got to the start of Striding Edge before being able to send anything. This shot shows Red Tarn and Catstycam in the background and was taken just past The Hole In The Wall and before I really started to regret not taking the crampons.

Hell Freezes Over Then Thaws

Training

This has been a week of inactivity and at least one trip to the pub and by lunchtime today I was restless and in need of some exercise. When the guys in the office got back from lunch in the pub I disappeared off and ran the HHR in the snow, slush and wet. It was even wetter experience than the infamous River Runnin as the slush was ankle deep most of the way down and the melt-water from the fields had produced a fair sized stream flowing all the way down from the Water Works (sic) to the gate and beyond.
The trail running shoes my Inov-8 Flyroc 345GTX, those ones I complained about ages ago really came into their own, grip in the snow was awesome!
