All the analysis was done using SAS EM 4.1 software. The prevalence of tracheobronchitis were higher in spring and autumn. Average atmospheric pressure, average temperature, highest air temperature, lowest air temperature, water-vapour pressure, degradation of visibility were positively correlated with the prevalence of tracheobronchitis. Factors that affected the incidence of tracheobronchitis were average atmospheric pressure, degradation of visibility, daily temperature difference and water-vapour pressure.

Experts from meteorological department pointed out that the reason why it snowed at that time is that the atmospheric pressure above the area dropped suddenly to 950 millibars. It was 20 millibars lower than the limit of the normal atmospheric pressure. In June, 2000, the temperature in Koppaonike City, a small town in the plain of Yugoslavia, was over 15 degrees centigrade all along. But in midday of June 17 it dropped suddenly to zero or below. Then a heavy snow fell on. This surprised the local residents. People went to street one after another to have a look.
