Representing low-intensity fire sensible heat output in a mesoscale atmospheric model with a canopy submodel: a case study with ARPS-CANOPY (version 5.2.12) [PDF]

Geoscientific Model Development, 2022
Mesoscale models are a class of atmospheric numerical model designed to simulate atmospheric phenomena with horizontal scales of about 2–200 km, although they are also applied to microscale phenomena with horizontal scales of less than about 2 km ...

Sensible heat fluxes control cloud trail strength

Quarterly Journal of the Royal Meteorological Society, 2023
AbstractConvective cloud bands known as “cloud trails” (CTs) are commonly found downwind of small islands (<(100) km2) throughout the world. They occur primarily in the afternoon, and are known to form in response to land–sea contrasts under the presence of background flow.

Variation Characteristics of Surface Fluxes on Different Underlying Surfaces and Their Relationship with Precipitation in the Canyon Area of Southeast Tibet

Gaoyuan qixiang, 2022
In this study， variation characteristics of surface fluxes were analyzed by using the eddy covariance observations from four stations of Pailong， Danka， Kabu， and Motuo in the southeastern gorge area of Tibet from November 2018 to October 2019.Pailong ...

Sensible Heat Flux From Arid Regions: A Simple Flux‐Variance Method [PDF]

Water Resources Research, 1995
Similarity models in the inner region of the unstable atmospheric boundary layer (ABL) are generally based on four dimensional parameters: buoyancy, friction velocity, surface heat flux, and the height above the land surface. In the free convection limit the friction velocity can be neglected, thus reducing the measurement needs in practical ...

The Characteristics of Land‐Atmospheric Water and Heat Exchange during Soil Freezing‐Thawing Process over the Underlying Surface of the Alpine Grassland in the Source Region of the Yellow River

Gaoyuan qixiang, 2022
The seasonal characteristics of water and heat exchange in the alpine grasslands are significant， and the freezing‐thawing process has an important impact on the land‐atmospheric water and heat exchange.Based on the observation data of the land surface ...

Sensible Heat Fluxes over an Urban Area—Vancouver, B.C. [PDF]

Journal of Applied Meteorology, 1974
The use of the eddy correlation technique is demonstrated for the measurement of sensible heat transfer in an urban area. The problems of time and space sampling (in the horizontal and vertical) are investigated. Based on 27 summer days of observations from a roof-top site in the central built-up part of Vancouver, the diurnal variation of sensible ...

Water and Heat Flux Characteristics of Alpine Wetland and Alpine Steppe under Grazing Enclosure on the Northern Xizang

Gaoyuan qixiang, 2023
Grazing enclosure has been extensively employed as a direct and effective management measure for grassland restoration on the Qinghai-Xizang Plateau.Enclosures significantly increased vegetation coverage and affected the water and heat exchange between ...

Measuring sensible heat flux with high spatial density [PDF]

2012 IEEE Sensors Applications Symposium Proceedings, 2012
Sensible heat flux is an essential quantity in the surface energy budget. Information about it is crucial for the derivation of models of air-surface interaction which in turn are needed for larger scale climate models. Sensible heat flux varies greatly across short distances and thus many sensors are required in order to obtain measurements of ...
