date: Fri, 16 Apr 1999 10:56:20 +0530 (IST) from: "Dr. Murari Lal" subject: Drift in Control (unforced GCM Experiments) to: m.hulme@uea.ac.uk My Dear Mike, We have analysed the unforced experiment's temperature data of the seven GCMs (global and annual mean). I am attaching here the time series of these data to show the model drift in over 200 years run. HadCM2 has no drift while CCCma has largest drift (Fig.2). NCAR model gives higher mean temperatures while GFDL gives lower mean temperatures (Fig. 1). I look forward to meet you in Bracknell on 3rd May. Cheers, Lal *************************************************************************** * Dr. M.
