Turbulent Fluxes in the Hurricane Boundary Layer. Part II: Latent Heat Flux

Journal of the Atmospheric Sciences, 2007
Abstract As part of the recent ONR-sponsored Coupled Boundary Layer Air–Sea Transfer (CBLAST) Departmental Research Initiative, an aircraft was instrumented to carry out direct turbulent flux measurements in the high wind boundary layer of a hurricane.

Foliage temperature and latent heat flux of irrigated wheat

Agricultural and Forest Meteorology, 1991
Abstract A series of 42 hourly measurements from a weighing lysimeter of foliage temperature provided a basis from which to evaluate the residual energy balance method for determining latent heat flux which incorporated foliage temperature measurements by an infrared thermometer.

Remote sensing of surface sensible and latent heat fluxes

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
The potential for radar/lidar remote sensing of the surface sensible and latent heat fluxes is discussed, and some preliminary results are given. The method utilizes a parameterization scheme involving observables measured by radar/lidar in the convective boundary layer. >

Partitioning of latent heat flux at a northern peatland

Aquatic Botany, 2007
Abstract The partitioning of latent heat flux ( Q E ) to vascular plant and moss surface components was assessed for a Sphagnum -dominated bog with a hummock–hollow surface having a sparse canopy of low shrubs. Results from porometry and eddy covariance measurements of Q E showed evaporation from the moss surface ranged from greater than 50% of ...

Sensible and latent heat flux estimates in Antarctica

1993
The assumption has been made that the net annual contribution of water by the processes of deposition and sublimation to the Antarctic Ice Sheet is zero. The U.S. Antarctic Program started installing reliable automatic weather stations on the Antarctic Continent in 1980.

Estimating daytime latent heat flux and evapotranspiration in Jamaica

Agricultural and Forest Meteorology, 2000
The suitability of the two-parameter scheme of De Bruin and Holtslag (1982) to estimate daytime latent heat flux and evapotranspiration in Jamaica was examined using meteorological data collected over fields of short grass. The study covered three different periods, January to February of 1994, January to February of 1990, and August to September of ...

Latent Heat Fluxes Through Soft Materials With Microtruss Architectures

Journal of Heat Transfer, 2008
Microscale truss architectures provide high mechanical strength, light weight, and open porosity in polymer sheets. Liquid evaporation and transport of the resulting vapor through truss voids cool nearby surfaces. Thus, microtruss materials can simultaneously prevent mechanical and thermal damage.

Tropical Gravity Wave Momentum Fluxes and Latent Heating Distributions

Journal of the Atmospheric Sciences, 2015
Recent satellite determinations of global distributions of absolute gravity wave (GW) momentum fluxes in the lower stratosphere show maxima over the summer subtropical continents and little evidence of GW momentum fluxes associated with the intertropical convergence zone (ITCZ).

Sensible and Latent Heat Flux Measurements over the Ocean

Journal of Physical Oceanography, 1982
Abstract This papar presents an extensive act of sensible heat (Reynolds flux and dissipation methods) and latent heat (dissipation method) flux measurements from a stable deep water tower and from ships on the deep sea. Operational difficulties associated with ship spray and flow distortion and with sensor calibration, response and contamination are ...

Flux-Variance Method for Latent Heat and Carbon Dioxide Fluxes in Unstable Conditions

Boundary-Layer Meteorology, 2009
Applied previously to momentum and heat fluxes, the present study extends the flux-variance method to latent heat and CO2 fluxes in unstable conditions. Scalar similarity is also examined among temperature (θ), water vapour (q), and CO2 (c). Temperature is adopted as the reference scalar, leading to two feasible strategies to estimate latent heat and ...
