Weather risk management by companies such as Delphi Weather Analytics. The weather risk market makes it possible to manage the financial impact of weather through risk transfer instruments based on a defined weather element, such as temperature, rain, snow, wind, etc. Weather risk management is a way for organizations to limit their financial exposure to disruptive weather events. By making a payment (a "premium") to a separate company that will assume the financial weather risk for them, an organization essentially is buying a type of insurance - the company assuming the risk will pay the buyer a pre-set amount of money which will
Anomaly matching condition Anomaly matching condition In quantum field theory, the anomaly matching condition by Gerard 't Hooft states that the calculation of any chiral anomaly for the flavor symmetry must not depend on what scale is chosen for the calculation if it is done by using the degrees of freedom of the theory at some energy scale. It is also known as the 't Hooft condition and the 't Hooft UV-IR anomaly matching condition. There are two closely related but different types of obstructions to formulating a quantum field theory that are both called anomalies: chiral, or "Adler-Bell-Jackiw" anomalies, and 't Hooft
