I want to know the answer to the following question:
In what year did von Neumann publish the paper Numerical Integration of the Barotropic Vorticity Equation
All the background I'm provided with is that "Von Neumann's interest in weather systems and meteorological prediction led him to propose manipulating the environment by spreading colorants on the polar ice caps to enhance absorption of solar radiation (by reducing the albedo).". Is that enough to answer the question?
