Changes in weather not only affect daily lives but also pose financial risks to businesses by influencing consumer demand for many products and affecting the quality of others. Retailers are encouraged to place orders for weather-sensitive products long before a season starts, but history has shown that unexpected weather patterns (an abnormally mild winter, for example) can result in significant drops in demand, leading to huge losses for companies and impacting overall economic activity. In June 2005, for example, Walmart reported that below-normal temperatures had caused a higher-than-normal inventory level in its weather-sensitive products. It is well understood in supply chain management that inventory of the wrong product in the wrong place at the wrong time costs money. ******The products of 70% of American companies are weather sensitive, and about half of its GDP is affected by weather. To minimize the risk from weather-sensitive demand, in 1999 the financial market introduced a financial instrument called the weather derivative. Weather derivatives allow a corporation to transfer its weather risk to another party willing to absorb it in the form of options, futures or swaps. The value of such derivatives is derived from an underlying variable — in the case of weather, temperature, rainfall, or snowfall. The Chicago Mercantile Exchange (CME), which introduced weather derivatives, traded $32B in weather derivatives in 2007.******Surprisingly, little research has been done on weather risk in supply chains. This research will be the first to investigate how one measurement of weather condition — temperature — affects the supply chain, how supply chains may be better coordinated considering weather-sensitive demand, and how supply chain contracts can be optimized by hedging weather risk using weather derivatives. It will develop theories and guidelines so retailers can implement supply chain management strategies, risk hedging, and contracts that minimize costs. ******Recently, retailers including Walmart, Rona and Home Depot, and energy companies including Duke Power and Progress Energy have moved towards taking weather information into account when predicting product demand to make supply chain decisions. Acknowledging the increasing importance and magnitude of weather risk in supply chain contracts, this research will not only play a critical role in helping astute retailers and producers minimize downside risk, but also enhance research knowledge in this area.

天气变化不仅影响日常生活，而且通过影响消费者对许多产品的需求和影响其他产品的质量，给企业带来财务风险。鼓励零售商在季节开始前很久就订购对天气敏感的产品，但历史表明，意外的天气模式（例如异常温和的冬季）可能导致需求大幅下降，导致公司遭受巨大损失，并影响整体经济活动。例如，2005年6月，沃尔玛报告说，低于正常温度导致其对天气敏感的产品的库存水平高于正常水平。在供应链管理中，众所周知，在错误的时间在错误的地点库存错误的产品是要花钱的。** 美国70%的公司的产品对天气敏感，其GDP的一半左右受天气影响。为了最大限度地减少对天气敏感的需求的风险，1999年金融市场推出了一种称为天气衍生品的金融工具。天气衍生品允许公司将其天气风险转移给另一方，后者愿意以期权、期货或掉期的形式吸收天气风险。这些衍生品的价值来自一个基础变量-在天气，温度，降雨或降雪的情况下。芝加哥商业交易所（CME）推出了天气衍生品，2007年交易了320亿美元的天气衍生品。令人惊讶的是，很少有人对供应链中的天气风险进行研究。这项研究将是第一个调查如何测量天气条件-温度-影响供应链，如何考虑天气敏感的需求，供应链可以更好地协调，以及如何通过使用天气衍生品对冲天气风险来优化供应链合同。它将发展理论和指导方针，使零售商可以实施供应链管理战略，风险对冲和合同，以最大限度地降低成本。** 最近，包括沃尔玛、罗纳和家得宝在内的零售商，以及包括杜克电力和进步能源在内的能源公司，在预测产品需求以做出供应链决策时，已经开始考虑天气信息。认识到供应链合同中天气风险的重要性和规模越来越大，这项研究不仅将在帮助精明的零售商和生产商最大限度地减少下行风险方面发挥关键作用，而且还将提高这一领域的研究知识。
