to occur. Radiation fog usually dissipates soon after sunrise as the ground warms. An exception to this can be in high elevation areas where the Sun has little influence in heating the surface. Valley fog Valley fog forms where cold dense air settles into the lower parts of a valley, condensing


level closer to the surface. Therefore, intense snowfall cools the surrounding air and makes it more likely for snow to reach the surface. 5 6 7 Afternoon temperature Rural Urban Rural Valleys: Valleys become cooler at night as cold air sinks into the valley from the hills. This is why you can often

there is little wind, skies are clear, and there is a covering of snow; the lowest temperatures occur away from the moderating influence of the sea, on the floors of inland valleys into which cold air can drain. It was under such conditions that the temperature fell to -23.3 °C, the lowest ever
