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.
