Parameterizing Scalar Transfer over Snow and Ice: A Review
Publisher: American Meteorological Society
Abstract: Evaluating the profiles of wind speed, temperature, and humidity in the atmospheric surface layer or modeling the turbulent surface fluxes of sensible and latent heat over horizontally homogeneous surfaces of snow or ice ...
A New Value of the von Kármán Constant: Implications and Implementation
Publisher: American Meteorological Society
Abstract: The von Kármán constant k occurs throughout the mathematics that describe the atmospheric boundary layer. In particular, because k was originally included in the definition of the Obukhov length, its value has both explicit ...
Two Experiments on Using a Scintillometer to Infer the Surface Fluxes of Momentum and Sensible Heat
Publisher: American Meteorological Society
Abstract: traditional use of scintillometry is to infer path-averaged values of the turbulent surface fluxes of sensible heat Hs and momentum τ (, where ? is air density and u* is the friction velocity). Many scintillometer setups, ...
The Temperature of Evaporating Sea Spray Droplets
Publisher: American Meteorological Society
Abstract: Evaporating sea spray droplets are often assumed to be at the temperature of a well-ventilated wet-bulb thermometer, Twet. Although this assumption may be accurate enough in practice, it is incorrect on theoretical grounds. ...
Sea Spray Generation at a Rocky Shoreline
Publisher: American Meteorological Society
Abstract: ith sea ice in the Arctic continuing to shrink, the Arctic Ocean and the surrounding marginal seas will become more like the ocean at lower latitudes. In particular, with more open water, air?sea exchange will be more ...
Spectral Measurements in a Disturbed Boundary Layer over Snow
Publisher: American Meteorological Society
Abstract: I have measured time series of the turbulent fluctuations in longitudinal (u) and vertical (w) velocity and in temperature (t) and humidity (q) with fast-responding sensors in the near-neutrally stable surface layer over ...
On the Kolmogorov Constants for the Temperature-Humidity Cospectrum and the Refractive Index Spectrum
Publisher: American Meteorological Society
Abstract: Structure parameters for the temperature (C?2) and humidity (Cq2) spectra and for the temperature-humidity cospectrum (C?q) that I have measured and additional values of C?q/(C?2Cq2)1/2 reported in the literature yield an ...
Spray-Mediated Enthalpy Flux to the Atmosphere and Salt Flux to the Ocean in High Winds
Publisher: American Meteorological Society
Abstract: Forecasts for the intensity and intensity changes of tropical cyclones have not improved as much as track forecasts. In high winds, two routes exist by which air and sea exchange heat and momentum: by spray-mediated processes ...
Three-Wavelength Method of Measuring Path-Averaged Turbulent Heat Fluxes
Publisher: American Meteorological Society
Abstract: Conceptually, electro-optical measurements of the path-averaged refractive index structure parameter Cn2 at three wavelengths should yield measurements of the vertical fluxes of sensible (Hs) and latent (HL) heat. With ...
