海洋热浪背景下海气湍流热通量资料的评估
Evaluation of air-sea turbulent heat fluxes data under the background of marine heatwaves
摘要
Abstract
In the summer of 2019,the Northeastern on Pacific region experienced a marine heatwave event called"Blob 2.0",which had a significant impact on the marine ecosystem.This study conducted a comprehensive analysis of the characteristics of air-sea turbulent heat flux during this event using the buoy data from National Data Buoy Center,the global objective flux product OAFlux,and atmospheric reanalysis datasets ERA5,NCEP2 and MERRA-2.The study also investigated the physical factors influencing these fluxes.The buoy observation revealed that during the"Blob 2.0"event,there was a positive increasing trend in latent heat flux,while sensible heat flux exhibited a negative decreasing trend.This phenomenon can be attributed to the positive increase in the air-sea specific humidity difference and the negative decrease in wind speed and air-sea temperature difference.Evaluation results indicated that all four flux data products underestimated the growth of latent heat flux,with ERA5 showing the closest agreement with buoy observation.Regarding sensible heat flux,both MERRA-2 and NCEP2 products exhibited a similar increasing trend as observed by buoys,with MERRA-2 showing a closer growth rate.However,OAFlux and ERA5 products showed an opposite trend compared to the observations.关键词
