Rain and pollen level?
Does rain/drizzle reduce pollen levels? It must take some pollen out of
the air, but what happens to it then? Just sits on the ground and waits for sunshine to dry it out? Or what? Hugh -- Hugh Newbury www.evershot-weather.org |

Or what? Yes. It then gets attacked by the ferocious bacteria that are hiding in the soil, waiting to pounce or poor, innocent pollen grains. More seriously, airborne pollen is generated by relevant plants (trees and grasses, mostly), and drops out very slowly and is taken out quite fast by rain. The process continues. Pollen, unlike seeds, does not remain viable in the soil, but its structure seems to be really quite durable and so it is used in archaeological invegigations of historical ecosystems.
