Pollen not only plays a role in allergies, but also influences the local weather. Especially in spring, when large amounts are released, it contributes to the formation of ice in clouds, which can increase rainfall.

Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation - even at temperatures between minus 15 and minus 25 degrees Celsius. ...
