This analysis examines the significance of pollen dissemination for meteorological factors. Things to do to achieve its goals. The goal - to assess pollen transfer and determine the amount of pollen in the air leading to meteorological factors. Objectives: Based on the city of Siauliai aeropalinologinių air mass trajectory data to analyze pollen carryover mechanism. According to the results of atmospheric models to determine rainfall, air temperature, wind speed, relative humidity influence to the abundance of pollen in the air. To evaluate the spread of pollen influencing factors and exclude pollen dispersion patterns. The callback trajectory analysis showed that for 2004-2013. flowering time was dominated by north west air Carryover. Air masses came from the first european region. Study of the prevalence of trees in northwestern Europe has shown that it affects pollen fetch before and after the application season. Pollen before the pollen season has been spreading mainly in Region 1. After spreading pollen pollen season was also the most in Region 1. From all six subjects plants: genus poplar, pine, hazel, alder, birch and oak pollen in season 2004 - 2013 was mostly blowing west (W) direction wind. In 2004 - 2013 period was found that the lowest correlation coefficients was obtained by comparing to meteorological factors (rainfall, wind speed) and the pollen concentration. It has shown that during the event the highest correlation coefficients were obtained between the air temperature and relative humidity. |
