Have you tried with temperature data and the digitlal elevation model?

Yes but i need more information about thé gradiant and orientation of this factor

For example, to cuantifyng hallways it's necessary using an GIS, as QGIS, it´s free. you can use r.watershed (QGIS) which calculates the flow accumulation of water in a dem, but it is the same for an catabatic wind in a frost event. The katabatic wind descends and stagnates at the bottom of the valleys, as well as for water draining.
