Catkin, the seed of poplar or willow, has white fluff and dances with the wind, like floating catkin, so it is called catkin. The weather with dry, high temperature, abundant sunshine, low humidity and certain wind speed is easy to cause catkins to drift.

In the morning and evening, as the temperature drops and the wind decreases, catkins will fly less.
