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
Foehn wind it expands and cools due to the decrease in pressure with height. Since colder air can hold less water vapour, moisture condenses to form clouds and precipitates as rain or snow above the mountain's upwind slopes. The change of state from vapour to liquid water is accompanied by heating, and the subsequent removal of moisture as precipitation renders this heat gain irreversible, leading to the warm, dry foehn conditions in the mountain's lee. This mechanism has become a popular textbook example of atmospheric thermodynamics and it lends itself to attractive diagrams. However the common occurrence of 'dry' foehn events, where
