  • Canada ; Hydrodynamics ; Methodology ; Quebec ; Statistics ; Stream ; Turbulence
  • This paper examines the effects of record length on the precision of turbulence statistics in fluvial boundary layers of gravel-bed rivers. From high-resolution velocity time series lasting 20 to 60 min, a bootstrapping method is used to determine
  • optimal record lengths and standard errors for 10 commonly used turbulence statistics.

  • Length of growing-season data wete obtained from 90 weather stations covering the core of the U.S. Corn Belt from 1911-2000 and analyzed qualitatively and statistically to ascertain if any systematic trends in warming were/are occurring within
  • the context of global warming. The AA. found that the 1920s were statistically cooler and the 1990s warmer. No discernible trend was statistically found throughout the 90-year-period.
