In this project we will price weather derivatives call options for snowfall in NYC. We will do this first using a statistical model built from historical data. We will also use this data to model the trend of snowfall over time. We will then consider a relatively simple physical model where snowfall is based on tempurature and percipitation. Then we combine these two models into a hybrid model. Last we will take a look at how changing the initial strike affects the payoffs for each model.
