We have "successfully" reproduced hurricane Helene from the AMMA field campaign using both GFS and ECMWF initializations. We have a nested 36, 12 and 4 km grid although the Helene shows up at all resolutions. Helene begins on the 9th of Sept. as an easterly wave and we have convection that corresponds well with Meteosat imagery. As part of our tests we tried 156 different combinations of parameterizations to find what produced the best results. You might look at <br clear="all">
