Virtual long-distance pollen dispersal of Pinus taeda. Virtual pollen release, using the Regional Atmospheric Modeling System (RAMS). The experimental settings are described in Bohrerova et al. (2009). Pollen was released from two locations, in North Carolina outer banks (black point) and South Carolina (grey point), at 6:00 pm, 27 March 2006 corresponding with observed peak of pollen release nearby. The dispersing pollen plumes (black – NC; grey – SC) are shown at 6:00 am, 36 h after the release. The wind was moderate, mainly toward the northeast. Mortality due to UV and vapour pressure deficit is resolved based on bench-scale observations. The pollen in the image, 36 h after release is c. 40% viable.
