Question of the course work:

Does temperature vary with height and aspect across The Devil’s Kneading Trough

Identification of the Question:

In my opinion there should be a relationship temperature varies with height and aspect. The theory behind those temperature varies is that cold air sinks down the valley during the night. To be more precisely it is the ground temperature which have been cooled down by the ground and so it became more dense than the rest of the air. As the ground air has now a high density it sinks down the valley. So the bottom of the valley should be colder than the rest of it. But during the day when the shortwave radiation of the sun starts to have an impact the bottom of the valley becomes warmer than the top because the bottom has more surrounded land which gets heated up. So my theory would be that temperature falls during the morning or night but rises during the day. Another theory of me would also be that the west sloap becomes quicker warmer than the east slope. This should be caused by the shortwave radiation of the sun. In the morning just the west sloap gets this radiantion because the east sloap lies in the shade.

It is possible to answer it by specific measurments.

Development of a Strategy:

To answer the question we need a suitable step valley where we can collect our primary data like ground and air temperature, profiles and aspect.The valley should be step so that we can height distances relative quickley. The secondary

data will the data that we can’t really colect from the valley like height and pressure.
