  1. Senior Project - Computer Science – 2005Simulating Milankovitch CyclesDerek FoxAdvisor: Prof. Hemmendinger Client: Prof. Hollocher (Geology) Milankovitch Cycles • Consist of three orbital parameters • Eccentricity of orbit • Obliquity of axis • Precession How Milankovitch Cycles Affect Climate • They determine the amount of solar insolation that reaches the latitudes of the Earth at a given time of year • The cycles have been correlated to the advance and retreat of glaciers during ice ages • This was verified in 1976 through the study of deep sea sediment cores that dated back 450,000 years. Three different Equations are used One for the latitudes where there is a sunrise and sunset Another for when there is no sunset (Arctic summer) A third for when there is no sunrise (Arctic winter) • My Program • Uses Milankovitch mathematics to visually simulate how solar insolation varies as the three cycles change • Has graphs that show the insolation change for specific latitudes over time • Has a model of the earth showing the insolation change at all latitude. • Design • Uses java for broad compatibility among different platforms • Convenient for publishing to the web On the web at: http://antipasto.union.edu/~foxd/hw/project1
