From the 06UTC forecast on 21st October 2015, the Met Office tropical cyclone prediction (CXML) data is now based on the higher-resolution MOGREPS-G forecasts. MOGREPS-G is run four times a day (00, 06, 12 and 18Z) using a 12-member ensemble with a grid length of approx 33km. Until now, the CXML data was based on the lower resolution MOGREPS-15 ensemble, even though MOGREPS-G data has been supplied to the TIGGE archive since July 2014. Note that each CXML dataset includes tracks from a lagged ensemble of 24 members, i.e., the current forecast and the forecast from 6 hours earlier. The CXML data are available via the NCAR archive at  http://rda.ucar.edu/datasets/ds330.3/ or see the TIGGE cyclone exchange page at http://cawcr.gov.au/projects/THORPEX/TC/index.html for further information.
