Abstract: During the last two decades (1979?2002), there has been an ever-increasing frequency of summer severe-rainfall events over Ontario, Canada. This observed upward trend is robust as demonstrated through the Mann?Kendall test ...

Abstract: In this study, a variational approach was employed to compute surface sensible heat flux over the Arctic sea ice. Because the variational approach is able to take into account information from the Monin?Obukhov similarity ...

Abstract: A variational method is employed to compute surface sensible heat fluxes over a deciduous forest using observed temperature, temperature variance, and wind. Because the variational approach is able to take into account ...

Abstract: A variational method is developed to estimate the aerodynamic roughness length and roughness scaling length for temperature based on wind and temperature measurements conducted routinely at an observational network. The ...

Abstract: Dry deposition velocities of gases and particles are highly dependent on surface type. In a numerical model, each grid cell may contain multiple surface types, each with a different deposition velocity. Therefore, some ...

Abstract: In this study, the authors have performed the variational computations for surface sensible heat fluxes over a large northern lake using observed wind, temperature gradient, and moisture gradient. In contrast with the ...

Abstract: he summer nonconvective severe surface wind (NCSSW) frequency over Ontario, Canada, in relation to regional climate conditions and tropical Pacific Ocean sea surface temperatures (SSTs) during the period of 1979?2006 is ...

Abstract: AbstractUnderstanding the aging characteristics of rejuvenated asphalt binders is vital for the effective selection and optimization of rejuvenators prior to their application in aged asphalt. Traditional chemical approaches ...

Abstract: AbstractStructural failure due to thermal cracking is a major form of damage to asphalt pavements in cold regions. Controlling this distress through the laboratory testing of asphalt binders continues to be a major challenge, ...
