三维的，湍流传播的空气中的孢子产生流行病学接触分布的特点是不断增加的顺风距离增加的长度尺度。这种行为是由于孢子从植物冠层逃逸到上面更快移动的空气中。这种接触分布在大距离处接近距离的逆幂律。基于这种类型的孢子传播的模拟流行病表现出空间疾病梯度，随着流行病的进展，这种梯度变得越来越浅。同向速度与距病灶的距离呈线性相关，与疾病严重程度无关[...]
The three-dimensional, turbulent dispersal of airborne spores yielded epidemiological contact distributions characterized by a length scale that continually increased with increasing downwind distance. This behavior was due to the escape of spores from the plant canopy into the faster moving air above. Such contact distributions approached an inverse power law of distance at large distances. Simulated epidemics based on this type of spore dispersal exhibited spatial disease gradients that became more shallow as the epidemic progressed. Isopathic velocities were related linearly to distance from the focus of disease, irrespective of disease severity [...]
