Type II solar radio bursts are produced by shock waves moving through the corona and solar wind. An existing theory predicts Type II dynamic spectra by considering electron acceleration at the shock, growth of Langmuir waves, and their conversion into radiation. Two contributions are presented, both relevant to space weather research and missions like STEREO. First, a more realistic 2-dimensional model for the solar wind is developed, based on spacecraft data at 1 AU, and illustrated for a specific period. It relates time to longitude and extrapolates to different heliocentric distances using MHD style equations and power-law temperature models. Second, the type II theory is combined with the data-driven solar wind model to predict the dynamic spectrum of a specific Type II burst. The results show reasonable semiquantitative agreement with observations. Issues and possible improvements are outlined.
