FORBES, April 9, 2012 by Todd Woody.
Started by a hedge fund meteorologist turned entrepreneur named Stephen Bennett, EarthRisk calculates the probability of market-changing bad weather up to 40 days in advance. That’s twice as long as the most farseeing conventional forecasts. On a visit to EarthRisk I’m taken by Bennett into “the Matrix,” the Web interface that shows these projections on grids and U.S. maps. EarthRisk defines extreme weather, for now, as a period of temperatures in the top or bottom 10% of the historic range that affects at least 10% of the area of a specific region of the U.S.
