Effect of Meteorological Parameters on Birch, Hazel and Mugwort Airborne Pollen Concentrations in 2004 2011 in Šiauliai
Journal Title: Jaunųjų mokslininkų darbai - Year 2012, Vol 36, Issue 3
Abstract
Birch, hazel and mugwort plants were selected for pollen analysis because of their different flowering periods and allergic reactions caused. Meteorological parameters such as wind speed and direction, relative humidity, rainfall, air temperature were identified. Furthermore, Spearman’s correlation coefficient was calculated in order to determine the relationship between meteorological variables and the airborne pollen concentration. Non parametric statistics were used because the data was not normally distributed. Multiple regression analysis was carried out so that the complex influence of meteorological parameters on airborne pollen concentration can be evaluated. The results of statistical calculations indicate that hazel season is the most affected by the weather conditions. The greatest quantities of birch, hazel, and mugwort pollen in Šiauliai are recorded when the southeast wind is blowing. Based on correlation analysis, the strongest connection was found between average air temperature, relative humidity, and pollen concentration. Describing the impact of a specific meteorological parameter on the pollen concentration is very difficult because the amounts of pollen in the air depend on a complex effect of meteorological factors.
