Abstract: Generally speaking, in continental climates thick depth hoar layer may develop near at or near the ground, where in maritime climates a compacted snow or wet grain layer tend to develop at or near the ground. However, it is common knowledge that even in maritime climates where wind erosion of shallow areas of the snow-pack is seen, a depth hoar layer often develops. In some cases this phenomenon can be linked to the cause of serious avalanche accidents. Observations of this particular development of depth hoar were made in the maritime climate in Japan during 04-06 winters for which results follow. -Rainfall has a strong influence of deterring the development of depth hoar. -Even if the total snow-pack becomes saturated / become wet grains from rainfall, transformation back into depth hoar is possible -To estimate the development of such depth hoar layer(s), one must consider the timing and frequency of rainfall events.
