The nearest upwind source for this pollen is populations growing in southern Oklahoma and central Texas, at distances of 200 km and 600 km respectively. Long-distance dispersal of J. ashei pollen into the Tulsa area shows a strong correlation with the trajectories of wind blowing across southern populations before traveling north towards eastern Oklahoma. The strong tie between climatic conditions and the occurrence of this aeroallergen within the Tulsa, Oklahoma, atmosphere provided a unique opportunity to forecast the dispersal, entrainment, and downwind deposition of this significant aeroallergen. Forecasts of long-distance J. ashei pollen dispersal began during the winter of 1998/1999. Each forecast uses defined climatic parameters to signal pollination at each source site. Coupled to these estimates of pollen release, forecast weather conditions and modeled wind trajectories are used to determine the threat of dispersal to downwind communities. The accuracy of these forecasts was determined by comparing the forecast "threat" to aerobiological records for the same period collected in the "Tulsa region". Analysis of the two seasons revealed only a single occurrence of "high" or "very high" pollen concentrations in Tulsa not directly linked to "moderate" or "severe" forecast threats from the southern source areas.}, number={2}, journal={INTERNATIONAL JOURNAL OF BIOMETEOROLOGY}, author={Water, PK and Keever, T and Main, CE and Levetin, E}, year={2003}, month={Dec}, pages={74–82} } @article{davis_eisner_wiener_main_1997, title={A flow visualization study of spore release using a wind tunnel-mounted laser light sheet}, volume={81}, ISSN={["0191-2917"]}, DOI={10.1094/PDIS.1997.81.9.1057}, abstractNote={A phase Doppler anemometry system in combination with a laser light sheet was used in a low-speed recirculating wind tunnel to examine the flow field around an individual leaf. Turbulence similar to that encountered near the surface of the earth in a neutral stability boundary layer was generated using a grid at the upwind end of the wind tunnel test section. Individual healthy and diseased plant leaves were introduced into the tunnel with the leaf tip pointing downwind. The Mie-scattered radiation from the spores departing the diseased leaf was captured on videotape. Image processing software was used to enhance the visual quality of the individual frames from the videotape and to make spore velocity calculations. Three main vortex regions around the leaf were identified. The importance of these regions to the separation of the spores from the leaf surface and their subsequent downwind movement was analyzed.}, number={9}, journal={PLANT DISEASE}, author={Davis, JM and Eisner, AD and Wiener, RW and Main, CE}, year={1997}, month={Sep}, pages={1057–1065} } @article{yao_arya_davis_main_1997, title={A numerical model of the transport and diffusion of Peronospora tabacina spores in the evolving atmospheric boundary layer}, volume={31}, ISSN={["1352-2310"]}, DOI={10.1016/S1352-2310(96)00181-1}, abstractNote={Abstract Numerical solutions of the diffusion equation of Peronospora tabacina spores from a finite-area source over flat terrain in the evolving convective boundary layer are presented. Temporal variations in the release of spores, atmospheric stability, wind speed, and eddy diffusivity are considered. The model also includes the vertical variations of wind and eddy diffusivity. The model results indicate that ground level concentrations decrease with time as wind speed and eddy diffusivity increase in the evolving convective boundary layer. The loss of P. tabacina spores due to deposition at the surface also decrease with increasing instability and wind speed. Deposition is found to be particularly important close to the source area.}, number={11}, journal={ATMOSPHERIC ENVIRONMENT}, author={Yao, CG and Arya, SP and Davis, J and Main, CE}, year={1997}, month={Jun}, pages={1709–1714} } @article{main_keever_1997, title={Spread and development of the 1997 blue mold epidemic in North America = Propagation et developpement de l'epidemie de mildiou de 1997 en Amerique du Nord}, number={3}, journal={Bulletin d'Information - CORESTA}, author={Main, C.
