Europe/Western Russia/Black Sea Region Turns Colder and Stormy for Early April

This week, a transition to a sharp negative phase of the Scandinavia Index takes place. During -SCAND, an upper trough becomes dominant across northwest Eurasia. Initially, temperatures turn quite cold across Northern Europe/Northwest Russia featuring some arctic air.

The northern surge of Sahara Dust was caused by a strong low-level southerly current of air across Northwest Africa in-between a small but potent upper trough on the Northwest Coast of Africa and an amplified upper ridge pattern over Northern Europe. The pattern is characteristic of the positive phase of the Scandinavia Index (+SCAND) regime.
