介绍了一种桦树花粉释放模型，并讨论了其主要特征。该模型的建立基于双阈值温度和模型，该模型描述了开花季节的传播，并与热时间模型自然地联系起来，以预测开花的开始和持续时间。对于开花季节，排放模型考虑了环境湿度和降水率，两者抑制花粉释放，而风速和湍流强度则促进花粉释放。这些依赖关系是使用空气生物学观察定性评估。该模型在季节开始和结束时引入松弛函数，反映了种群中单个树开花的概率特征。提出的桦树花粉发射模型的物理基础与文献报道的另一种综合发射模块进行了比较。该发射模型已在SILAM色散建模系统中实现，并在另一篇论文中对其结果进行了评估。
A birch pollen emission model is described and its main features are discussed. The development of the model is based on a double-threshold temperature sum model that describes the propagation of the flowering season and naturally links to the thermal time models to predict the onset and duration of flowering. For the flowering season, the emission model considers ambient humidity and precipitation rate, both of which suppress the pollen release, as well as wind speed and turbulence intensity, which promote it. These dependencies are qualitatively evaluated using the aerobiological observations. Reflecting the probabilistic character of the flowering of an individual tree in a population, the model introduces relaxation functions at the start and end of the season. The physical basis of the suggested birch pollen emission model is compared with another comprehensive emission module reported in literature. The emission model has been implemented in the SILAM dispersion modelling system, the results of which are evaluated in a companion paper.
