14 - 15 JUNE 1998 - OVERVIEW OF SATELLITE FEATURES IN THE SYNOPTIC SCALE DURING THE OBSERVATION PERIOD

by FMI

The following images (Fig. I00a-I00c) show the development of intensive MCS's, initially southeast of the Baltic States (56N/30E - 57N/36E) which, later in the evening, move towards Estonia and further over Finland. The large synoptic-scale frontal systems were located as follows:

A Warm Front cloud band was located over Finland and Sweden, and it was accompanied by precipitation.
A Cold Front cloud band was located over White Russia - Ukraine - Russia, and it was accompanied by rain and thunderstorms.
A CCB Occlusion was located over Romania - Ukraine, and it was accompanied by precipitation.

The development of MCS's within the warm air-mass was rapid resulting in huge multiple MCS in southern Finland, Estonia and White Russia. Many thunderstorms were observed within these MCS's.
