[Effect of weather on the occurrence of cerebral stroke].

In this paper a set of medical and meteorological data for the period of years 1985-1987 is elaborated and statistically evaluated in order to find correlations between daily occurrence of ischemic and haemoragic forms of cerebral stroke and particular biotropic types of weather. For tracing we gathered clinical medical data from eight health-service institutions in Bratislava. We compared both annual and seasonal courses of biometeorological types of weather in the investigated period with annual and seasonal courses of the followed sickness rate. We have found that the most unfavourable weather type is the central low pressure area with transition of the frontal system. The most favourable atmospheric type is a sunny weather in the warm high pressure area without surface inversion. (Tab. 2, Fig. 4, Ref. 10.)
