Symposium on nowcasting and very-short-range forecast


More than 150 weather experts from over 20 countries and regions attended the World Meteorological 4th International Symposium on Nowcasting and Very-short-range Forecast 2016 from 25-29 July in Hong Kong, China. The theme was ‘From Nowcasting and Mesoscale Modelling: Sciences to Services’.

Nowcasting and mesoscale numerical modelling are currently among the most active research areas in meteorology. The aim is to provide rapidly updated, high precision meteorological products and services from data collection to the end users in order to  predict high impact weather a few hours in advance.

This year's symposium carried a special theme on aviation nowcasting, with the participation of air traffic management and airlines representatives.

"This is an emerging subject which requires significant efforts in advancing the nowcasting and modelling technologies so as to meet the needs of the next generation global aviation in the next 15 years and beyond,” said the Director of the Hong Kong Observatory (HKO) and the President of the WMO Commission for Aeronautical Meteorology, Shun Chi-ming.

The seminar was jointly organized by the WMO World Weather Research Programme, the Hong Kong Observatory, the Hong Kong Meteorological Society and the Institute of Environment, Energy and Sustainability (IEES) of The Chinese University of Hong Kong (CUHK).

Scientific findings presented during the symposium included:

  • Very short-range forecasting of high impact weather; 
  • New observational instruments;
  • Advances on mesoscale Numerical Weather Prediction (NWP) model, data assimilation and ensemble prediction;
  • Urban meteorology;
  • Transfer of the science on nowcasting and very-short-range forecasting to services; Applications of nowcasting of severe weather in public weather services, transportation and public utilities;
  • Socio-economic impacts;
  • Verification and validation.

“Occurrence of severe weather events causes considerable disruptions to our social and economic activities.  Nowcasting and very-short-range prediction of severe weather events present stiff challenges to our forecasters and decision makers. Therefore, advancements in the accuracy of such short-term forecasts are of significant benefit to our society,” said Fung Tung, Associate Vice-President of CUHK and Associate Director of IEES.

‘The implementation plan of WMO/WWRP covers societal challenges of extremes, water, urbanization and new technologies,’ said Alexander Baklanov from WMO. “Working groups of WWRP are carrying out projects on High Impact Weather, Polar Prediction and Sub-seasonal to Seasonal Prediction,” he said.

The symposium is held once every three or four years. It is the first time that it has been held in Asia.
