Pollen Star Ring: View from Finland | Solar System Science
"Pollen ring in the evening sun. Caused by pine trees."
The peak pollen release often aligns with warmer temperatures and increased sunlight. This triggers the pine trees to release their pollen. Generally, you can expect to see significant pollen levels from late spring through early summer. The pine pollen grain has two special air-filled bladders that help it achieve flight. Pine trees produce large amounts of pollen because they rely on the wind to deliver the pollen to their female cones.
Finland is a Nordic country in Northern Europe. It borders Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland to the south, opposite Estonia.
