Description

The chronologically changing behaviour of CMs during a cold air outbreak in the Mediterranean is the focus of interest.

Content

Case study of various CMs over Eastern Europe and a WV Eye over the Mediterranean. Chronologically changing behaviour of CMs during a cold air outbreak in the Mediterranean is the focus of interest.

Description

In this case study a Mesoscale Convective System associated to a convergence line is described.

Content

In this case study a Mesoscale Convective System associated to a convergence line is described. The zone of strong convective activity initially extends from Estonia to Russia. During the life cycle it propagates to the North and finally reaches Southern Finland and causes heavy precipitation.

Description

In this case study a low pressure systems with associated cloud bands over Eastern, Northeastern and Southern Europe is described.

Content

Typical summer time distributions of low pressure systems with associated cloud bands over Eastern, Northeastern and Southern Europe (Black Sea Low). Development of frontal parameters and weather events relevant for Scandinavia are discussed in detail.

Description

This case study discusses strong convective activity in a pre-frontal convergence line over northeastern Europe.

Content

The purpose of this study is to investigate the circumstances which caused this particular pre-frontal convergence line to develop and to compare them with those typical for the conceptual model Non-orographic Convergence Line.

Description

This case study a polar low affected north-western Europe between the 27th and 29th of January 2004.

Content

In this case a Polar Low affected North-western Europe between the 27th and 29th of January 2004. The Polar Low moved along the Norwegian coast then southwards in a northerly flow and turned over the North Sea in the direction of the German Bight. Eventually the Polar Low made landfall over the border between the northern parts of The Netherlands and Germany.

This case study discusses a front decay over central and northern Europe, the impact of CA and distinct sinking within a frontal cloud band.

Content

Front Decay over Central and Northern Europe. The impact of CA and distinct sinking within a frontal cloud band is shown in detail.

Description

Storm Janika over Greenland, the Northern Atlantic and Finland.

Content

From 10th to 16th of November 2001 a series of intensive storms moved over the Northern Atlantic and passed through Scandinavia and Finland to the east. A few of the storms were remnants of hurricanes but the one storm that caused extensive damage, at least to Finland, was of a smaller scale. It was named "Janika".

Description

This catastrophic case describes two Mediterranean low pressure systems, propagating along a so-called 5b path.

Content

In August 2002 two Mediterranean low pressure systems developed, taking a so-called 5b path. Such occurrences are rather unusual in summer as was the very rapid repetition rate of two events within about 8 days. The first event happened between 06 and 08 August, the second between 10 and 13 August.

Description

This case study discusses a Dark Stripe visible in water vapour imagery behind a Cold Front.

Content

This case study will concern a Dark Stripe visible in water vapour imagery behind a Cold Front. This Dark Stripe indicates the presence of descending dry air, which can be of stratospheric origin. The stripe develops along the cyclonic side of the white water vapour band. Typical places of appearance of Dark Stripes are the rear of Cold Fronts and Occlusions, and the forward sides of Warm Fronts.

Description

This case study deals with convective cells over Austria in a pre-frontal unstable airmass causing exceptionally intensive hail which is a rare phenomenon in this region.

Content

This case study deals with convective cells over Austria in a pre-frontal unstable airmass causing exceptionally intensive hail and a tornado in Vienna which is a rare phenomenon in this region.
