![]() ![]() ![]() Whiteout, white-out, or milky climate is a weather situation in which the contours and landmarks in a snow-covered zone develop into virtually indistinguishable. Now, we've were given all the detailed explanation and resolution for everybody, who is interested! Asked by: Prof. This last type happens when low cloud covers the hills, diffusing the light and making the entire environment turn white, even when it is not snowing.This is a query our professionals keep getting once in a while. Dimming your torch beam can reduce, but not totally eliminate, this effect.Ĥ. On pitch-black nights, even light falling snow can reflect the light from head torches and create a whiteout. In blizzard conditions the volume of wind-blown snow, often mixed with ice particles, is so dense that it is all you can see.ģ. During a normal snowfall, a sudden heavy flurry, albeit usually brief, can sometimes strike and create whiteout conditions.Ģ. Throwing a rope or a snowball out in front is a good method.ġ. How the ground lies ahead if you are moving up or down. With the loss of an obvious event horizon, it can be difficult to assess Instead of going straight to your attack point (next destination), use the technique of Aiming Off, if you can.ħ. If there is a handrail nearby which is near impossible to miss, aim for it.Ħ. If there is a forest nearby head for this it will afford some protection from the weather too.ĥ. If your route was from a lower altitude, follow the old track back as it may also give some kind of contrast in the snow.Ĥ. Whiteouts are frequently a local phenomenon and related to a specific altitude so, if safe to do so, move to a lower position if it is not too far to travel. #White out conditions how toIt will tell you where you are and where to go, but it is important to stress that it does not tell you how to navoid snowdrifts, ice that has covered open water, and avalanches.ģ. If you have one, use your handheld satnav (GPS). Before moving off, be absolutely certain that you know exactly where you are you cannot navigate safely to another point if you don’t know where you have started from.Ģ. ![]() If you must move, there are some measures you can employ to minimise this risk.ġ. ![]() The risks are high and in the absence of a horizon we easily lose our spatial orientation which can also lead to vertigo. They also increase the risk of falling over a precipice or walking on to a corniced edge of snow that could collapse.įrequently, flurries of snow that cause whiteouts soon pass and the best course of action is to stay put, if it is safe to do so. They are dangerous because it is very easy to get disorientated, even within a couple of metres, and the risk of becoming confused and lost is very real. You lose perspective, you cannot judge distance… or, indeed, see anything at all. It erases all signs of shadow and definition. A whiteout is when you lose the horizon and everything around you, including the sky, appears white. In this issue we are going to focus on the one winter condition that you can encounter anywhere, from the walking in the North Yorkshire Moors to skiing in the Alps: a whiteout. In this issue we are going to concentrate on two key navigational tools that can get people out of trouble and show you how to perform them correctly. Low pollen and air pollution means the air is clearer and permits high visibility over great distances.Īdd to this the sheer magic that a painting of frost can add to your environment, winter becomes one of the most beautiful times of the yearn to explore the great outdoors.Sub-zero temperatures can make boggy ground, such as that found on much of the Cheviots and in the Scottish Borders, firm and easier to move over.The low sun can cast long shadows, highlighting contour features much more than at other times of year, making the interpretation of shapes on the land to the contours on your map more straight forward.Everyone is aware that shorter daylight hours and the chance of significantly reduced visibility can make navigating in winter more difficult, yet there are also big advantages when navigating in winter. ![]()
