摘要：

A simple model for the immission of pollen grains from large area sources into the atmospheric convective boundary layer is presented. The terrain is assumed to be homogeneous (like a large plain) and the sources are assumed to be uniform over horizontal distances of the order of 10 km. The model requires the production rate of pollen to be specified, as well as the temperature as a function of time or analogous atmospheric parameters. The results compare well with data measured in the Po Valley, Italy.
