Abstract
The study concerns research into the connection
between atmospheric circulation over
the area of Central and Eastern Europe, and the
occurrence of days with thunderstorms in Poznañ
(Poland). The analysis of lower synoptic
maps for the researched period 1951–2000 made
it possible to isolate seven types of synoptic
situations characteristic of days with thunderstorms
on the area of Poland. During research
based on the use of logistic regression, a determination
was made of the influence of various
synoptic situation types on thunderstorm
activity in one of the polish meteorological station
– Poznañ. An indication was made of type 2
of synoptic situations that is particularly conducive
to the appearance of days with thunderstorms.
This type is also characterised by the
highest probability of the occurrence of stormy
days. It has to be pointed out that type 2
synoptic situation may be the cause of very
violent storms not only in Poland, but also in
Europe or the USA. This is reflected in the
descriptions of individual cases of violent storms
or their accompanying phenomena occurring
over Europe (PIAGET 1976; COURVOISIER et al. 1979;
KURZ 1985, 1986; KOLENDOWICZ 2003, 2005), and
the results of the studies conducted by CHANGNON
(1985, 2001), WALKNER (1992) and KOLENDOWICZ
(1998) pertaining to the analysis of
a greater number of violent storms.
