Type II solar radio bursts are produced by shock waves moving through the corona and solar wind. An existing theory predicts the Type II dynamic spectrum by considering electron acceleration at the shock, growth of Langmuir waves, and their conversion into radiation. Two contributions are presented. First, a more realistic 2-dimensional model for the solar wind is constructed for specified time periods from spacecraft data at 1 AU. It converts time to longitude and extrapolates to different heliocentric distances using MHD-like equations and power-law temperature profiles. Second, the type II theory is combined with the data- driven solar wind model to predict the dynamic spectrum for a specific Type II burst. The results show good qualitative agreement with the observations, as well as demonstrating that shock interactions with corotating interaction regions lead to enhanced emission. The new theoretical model for Type II bursts is relevant to NASA's STEREO mission and space weather research.
