Hi Ray, Attached is a first round of plots for you to look at: data/model comparison of the seasonal variations in the nightly mean temperature and intensity at Adelaide and Alice Springs. Let me know if there are any other seasonal plots that might interest you. I'm slowly making my way from longer time-scales to shorter time-scales, and I'm now working on some nice color plots showing multi-day waves.... Lynette Lynette J.
