In particular, the regional specialized metrological centres in New Delhi and Tokyo, working in the framework of the WMO, are training national forecasters. At their joint session in 2015, TC and PTC members recommended the further scaling up of such training. The project uses a ‘cascading forecasting process’ to provide guidance from global and regional weather models to participating countries such as Vanuatu and the Solomon Islands. In this way, national forecasters do not need to invest in expensive computing power.
