介绍了中尺度大气模式METRAS在橡树花粉扩散研究中的推广应用。我们将功能花粉排放，花粉活力和花粉沉积到METRAS和模拟花粉传播的规模可达200公里。模拟的基础是一个真实的景观结构，包括地形，土地利用，橡树林的位置和大小。在2000年开花季节的两个典型的日子里，我们模拟了一个单一的橡树林的橡树花粉散布，估计每年的花粉产量为10亿花粉粒/m（2）森林表面。根据模拟日的气象情况，花粉云约10花粉/m（3）可能会从源头延伸到30公里。在橡树林的下游，大约1,000花粉/m2沉积到25 km的距离，并且较低的花粉量沉积到100 km的距离。这些花粉浓度和沉积值在已发表的实地研究范围内。总体而言，它表明，中尺度大气模式是适用于模拟景观水平上的花粉传播。
We present the extension and application of the mesoscale atmospheric meteorology model METRAS for dispersion of oak pollen. We incorporated functions for pollen emission, pollen viability and pollen deposition into METRAS and simulated pollen dispersal on a scale of up to 200 km. The basis of the simulations is a real landscape structure that includes topography, land use, and the location and size of oak stands. We simulated the oak pollen dispersion of one single oak stand with an estimated annual pollen production of 1 billion pollen grains/m(2) forest surface on two exemplary days of the flowering season in 2000. Depending on the meteorological situation of the simulated days, a pollen cloud with about 10 pollen/m(3) may extend up to 30 km from the source. Downstream of the oak stand, approximately 1,000 pollen/m(2) deposited up to a distance of 25 km, and lower amounts of pollen deposited up to 100 km away. These values of pollen concentration and deposition lay within the range of published field studies. Overall, it is shown that mesoscale atmospheric models are applicable to simulate pollen dispersal on the landscape level.
