[Effect of the weather on morbidity dynamics in a large city. An investigation on the population of Munich].

The dependence on the weather on the nightly morbidity figures can be demonstrated in a total of 10,200 patients who have used the Munich Emergency Medical Service within 3 months. No prognostic inferences emerge which could be useful in practice, because the effect of the weather is at first almost completely masked by the effect of the weekly rhythm and trend, and only a retrospective analysis over a longer period can make its substantiation possible. Using the Tölzer Weather Phase Schemes, a significant increase in the morbidity figures can be demonstrated for the passage of fronts, inversion positions and the development of warm damp air conditions near the ground. An effect on the number of notifications of illness on meteorologically perfectly defined foehn days is not demonstrable. Only an indifferent effect on the general symptomatology can be attributed to the weather; there is no statistically significant evidence of a specific effect on a single clinical picture.
