中文摘要
极端天气可以提前数天预报,但其对农业的影响仍然难以预测:预报告诉我们风暴将袭击何处,而非哪些作物会受灾或有多少处于风险中,而能够提供答案的记录分散在许多来源中。我们提出 WxCrop,第一个通过因果分析检验物理可解释天气指数来判断农业危害的智能体,也是第一个结合天气和农业信息来可靠预测过去和预报日期作物损失的系统。我们在佛罗里达州的飓风、冰冻和干热天气上进行了验证,损失模型分别基于保险记录校准,同样的程序可扩展到其他危害和地区。三项检查展示了其可靠性:飓风指数以 0.98 的 AUC 检测到记录的气旋日,保留年份中记录的损失被复现到 2% 以内,独立的生产记录证实了县级排名(秩相关 0.63)。用户可以向智能体询问每种作物组的损失占预期季节价值的比例,每个数字都有来源,使政府、种植者和科学家能够快速应对农业灾害。
原文摘要
Extreme weather is forecast days ahead, yet its consequences for agriculture remain hard to predict: a forecast says where a storm will strike, not which crops will suffer or how much is at risk, and the records that could tell span many sources. We present WxCrop, the first agent that judges agricultural hazards from physically interpretable weather indices examined by causal analysis, and the first that combines weather and agricultural information to predict crop loss reliably for past and forecast dates. We demonstrate it in Florida on hurricanes, freezes and dry heat, with a loss model calibrated on insurance records for each, and the same procedure extends to other hazards and areas. Three checks show reliability: the hurricane index detects recorded cyclone days with an AUC of 0.98,...
