Hurricane models are continuously upgraded and refined by mathematicians like Dr. Michael Navon at SCS. He and his FSU group, and collaborators across the US, are working on improving the mathematical foundation of the models. One of the questions Dr. Navon is currently working on is data assimilation. Simply speaking, this is about how to update your model with new data from observations, and about how much you should trust new measurements compared to the well-founded data from the model, which is based on thousands of earlier measurements.
A recent article in Science suggests that the number of whales before hunting started was much larger than anyone has suspected. These controversial results originated from calculations on genetic variation among today's whales. Peter Beerli at SCS developed the method and the computer tool used in the study.
