An exploratory analysis of lightning-ignited wildfire data for the Warren Region of Western Australia was carried out for the period from April 1976 to December 2016. Temporal patterns in the series were examined in terms of characterizing the seasonal cycle, and detecting long-term trends and changes in seasonality over time. A generalized additive modelling approach was used to ensure that temporal features were determined by the data rather than a priori assumed mathematical forms (e.g. linear or low-order polynomial functions). The spatial organization of the data was evaluated using concepts from the theory of stochastic point processes. Results indicate a strong seasonality in the monthly lightning ignition series, the presence of a long-term trend and an interaction between trend and seasonality. There is also strong evidence of spatial variation in the number of ignitions per unit area in terms of location and distance from nearest ignition. Within the Warren Region, observation platforms for fire detection and reporting protocols have remained stable over the period of record, and changes in land use are unlikely to have altered the pattern of lightning ignition. Thus, the above results might reflect an interplay between: landscape attributes (e.g. vegetation classes, elevation, slope, aspect); changes in rainfall and fuel moisture; changes in fuel management practices; and, perhaps, an increase in the frequency of dry thunderstorms and fire weather conditions.

对1976年4月至2016年12月的西澳大利亚州沃伦地区的闪电点燃的野火数据进行了探索性分析。从表征季节性周期和发现长期趋势的角度研究了该系列的时间格局。以及季节性随时间的变化。使用通用的加性建模方法来确保时间特征是由数据确定的，而不是先验假定的数学形式（例如，线性或低阶多项式函数）。使用随机点过程理论中的概念对数据的空间组织进行了评估。结果表明，每月闪电点火序列具有很强的季节性，长期趋势的存在以及趋势和季节性之间的相互作用。在位置和距最近点火的距离方面，也有强有力的证据表明每单位面积点火的数量会发生空间变化。在沃伦地区内，用于火灾探测和报告协议的观察平台在记录期间一直保持稳定，土地用途的变化不太可能改变雷电的点火方式。因此，以上结果可能反映了以下因素之间的相互影响：景观属性（例如，植被类别，海拔，坡度，坡向）；以及 降雨和燃料水分的变化；改变燃料管理做法；也许还会增加干雷暴和大火天气情况的发生频率。火灾探测和报告协议的观测平台在记录期间一直保持稳定，土地用途的变化不太可能改变雷电的点火方式。因此，以上结果可能反映了以下因素之间的相互影响：景观属性（例如，植被类别，海拔，坡度，坡向）；以及 降雨和燃料水分的变化；改变燃料管理做法；也许还会增加干雷暴和大火天气情况的发生频率。火灾探测和报告协议的观测平台在记录期间一直保持稳定，土地用途的变化不太可能改变雷电的点火方式。因此，以上结果可能反映了以下因素之间的相互影响：景观属性（例如，植被类别，海拔，坡度，坡向）；以及 降雨和燃料水分的变化；改变燃料管理做法；也许还会增加干雷暴和大火天气情况的发生频率。改变燃料管理做法；也许还会增加干雷暴和大火天气情况的发生频率。改变燃料管理做法；也许还会增加干雷暴和大火天气情况的发生频率。
