An Observational and Model Characterization of Vertical Structure of Wind Fields over Eastern United States: A Case Study of Sterling, Virginia

摘要: The performance of twenty GCMs that participated in the Coupled Model Intercomparison Phase 5 (CMIP5) is evaluated at Sterling, Virginia, by comparing model outputs with radiosonde observational dataset and reanalysis dataset. We CMIP5 models their ability to simulate wind climatology, seasonal cycle, interannual variability, trends pressure levels from 850 hPa 30 hPa. also addressed question number years required detect statistically significant using measurements. Our results show successfully reproduced observed climatological annual mean zonal speed vertical distribution. They capture zonal, meridional, distribution stronger (weaker) during winter (summer) season. However, there some disagreement magnitude profiles among models, reanalysis, observation. Overall, obtain trend decreases increasing level except for upper troposphere. Although profile variability agree observation, not significant. This indicates detection on local scale challenging because small signal-to-noise ratio problems.
