✦ Synopsis

The present paper is a study of summer snowfalls over the Mount Olympus range (altitude > 2500 m) in northern Greece. This occurs about three times every summer and is, of course, linked to the atmospheric circulation over Europe. At least two days before snowfall, a deep trough, reaching almost to the northern end of the western Mediterranean, causes a strong southward invasion of cold air. This cold air-mass movement results in cyclogenesis near northern Italy. A depression is formed which moves to the east, causing bad weather over northern Greece and a snowfall over the higher part of Mount Olympus. The freezing of air masses over the mountain area is so strong that the dry-bulb freezing level found at 640 hPa two days before snowfall, reaches 710 hPa immediately after snowfall.
