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. 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. |

The Met Office TIGGE data now includes data from the higher resolution, 7-day MOGREPS-G global ensemble (rather than MOGREPS-15, as used up to 00Z 15th July). The new data are being provided in near-real time from 00Z 6th November, and it is planned to back-fill the gap in due course. The new ensemble data includes 12 members run four times a day, with a reduced number of parameters. See attachment below for more details. |
