Atmospheric analysis

Mountainous/Alpine regions
Mount Cook
Mountainous areas are subject to heavy snowfalls, high winds, and low temperatures. Semi-permanent snow and ice fields exist at about 1000-1100 metres during winter. Anticyclones often bring settled weather in summer, but clear cold conditions in winter with severe frost. Winter and spring are usually more unsettled than summer and autumn.
