This graph is an example of pollenconcentration during three different types of days. Day 1 shows airborn pollen between 9:00 and 17:00. Day 2 shows a pollenpeak during the early morning hours. Day 3 shows a peak in the evening. Weatherconditions, like a rainshower, a sunny or cloudy day, have big influence on the hourly […]
Are winddirection, pollenconcentration and pollenpressure correlated? It very much depends on your location. This graph shows that for the Netherlands a south-east wind is less favourable, as it can bring pollen from Germany and Belgium. When you live on a small island like Helgaland, every winddirection is favourable. Besides winddirection also windspeed is correlated.
Are windspeed and pollenconcentration correlated? It seems that in periods with a low windspeed the average complainlevel is higher that during periods of high windspeed. A more detailed graph is not available yet.
Are temperature and pollenconcentrations related? This graph shows the correlation between the average complainlevel and the temperature during two months.
Are rain and pollenconcentrations correlated? There seems little doubt about that. Rain can wash the air clean from pollen. This graph shows the correlation between the average complainlevel (purple) and rainfall (blue) during two months. The rainfall seems to press down the complainlevel. On the other hand a short rain shower, can trigger pollenrelease by […]
