Abstract: Laboratory experiments with finite-amplitude baroclinic waves arising from instability of a two-layer f-plane shear flow are reported. They show that as the system becomes more and more supercritical, as measured by ...

Abstract: Simple expressions are presented for the corrections to the classic Ekman pumping law We = ?·curl(τ0/f) due to nonlinear advection effects in the surface boundary layer. These involve products of the surface Reynolds stress, ...

Abstract: Limit-cycle type oscillations of the amplitude of a baroclinic wave field, which has grown by instability on a background zonal flow, have been observed experimentally in a rotating cylinder containing two immiscible fluid ...

Abstract: This paper discusses the nature of quasi-geostrophic ?-plane flow over an idealized set of ridges with height h=F(y/Ly) cosx/Lx. When the mountains are highly anisotropic, with scale factor ratio Lx/Ly?1, the asymptotically ...

Abstract: Airbone Doppler lidar wind measurements were obtained in the lee of Mount Shasta in northern California on 28 August 1984. These data consist of line of sight wind vectors at flight level (3000 m) and along planes tilted ...

Abstract: rojections of greenhouse gas concentrations over the twenty-first century generally rely on two optimistic, but questionable, assumptions about the carbon cycle: 1) that elevated atmospheric CO2 concentrations will enhance ...

Abstract: AbstractPhenology studies are a critical tool for identifying the ways that changing climate affects species and ecosystems. Here, a phenological framework was used to assess the sensitivity of human behavior to temperature ...

Abstract: his study is an application of the Statistical Severe Convective Risk Assessment Model (SSCRAM), which objectively assesses conditional severe thunderstorm probabilities based on archived hourly mesoscale data across the ...

Abstract: his study introduces a system that objectively assesses severe thunderstorm nowcast probabilities based on hourly mesoscale data across the contiguous United States during the period from 2006 to 2014. Previous studies ...

Abstract: Arsenic-contaminated groundwater affects millions worldwide. A cement-based filter medium (CBFM) can be used to remediate heavy metals from groundwater. Recently, the desulfurization of flue gas in coal-fired power plants ...
