A long heavy rain period in the Baltic States and Finland: 9-10 July 2005
During the 9th and 10th July the Baltic States and Finland experienced heavy rain as a wave-cloud formed in moist and warm south-easterly air stream.
This study concentrates on two areas at the opposite sides of the low pressure area. The objective is to provide a detailed insight into the mechanisms that govern the formation of convection within a cold front (Finland) as well as prolonged rain within an occluded front (Lithuania).
In Lithuania the event was characterized by extreme rainfall (locally more than 250 mm in 3 days), leading to floods and severe damage. The south-westerly gusts on the 10th August caused uprooting of trees and further economic loss in excel of 45 million Euro. In Finland the most remarkable events were those connected with the passing of the cold front in the evening of August 9, associated with the intensive precipitation and lightning.
