我国极地数值天气预报系统的初步建立与应用
Polar numerical weather prediction system: preliminary establishment and application
摘要
Abstract
National Marine Environmental Forecasting Center has established an operational polar numerical weather forecasting system (PNWFS),which is based on mesoscale numerical model Polar WRF and 3DVAR data assimilation method with a spatial resolution as high as 3.3 km.Validation result shows that PNWFS can predict the evolution characteristics of short-term weather pattem over Polar Regions,and therefore meet the needs of Chinese Antarctic and Arctic expedition as well as commercial shipping.Within the past five years,in addition to regularly providing numerical weather prediction products for Polar Regions,PNWFS also performs well in the weather forecasting support of several important events,such as (1) the rescuing of XUELONG icebreaker which was trapped in Antarctica sea ice in 2014,(2) the first cruise of Chinese commercial vessel in Arctic passage in 2013,and (3) the operating of Chinese fixed-wing aircraft in Antarctica.In future,more efforts will be made to PNWFS in the aspects of data sources,development of model and product,and the product distribution,in order to provide a more accurate and reliable weather protection for Chinese polar scientific expedition and shipping industry.关键词
