Current ‘physically based’ soil-vegetation-atmosphere transfer (SVAT) schemes use increasingly complex descriptions of the physical mechanisms governing evapotranspiration fluxes, thereby requiring the specification of a large number of parameters controlling the vertical fluxes over a single...
This paper has investigated the within-season rainfall variability at selected sites (Accra and Tamale) in two savanna zones of Ghana. The average duration of the dry and wet spells was estimated for each site from the long-term rainfall probability parameters. At Accra, the average duration of...
This study was part of the Boreal Ecosystem-Atmosphere Study (BOREAS). It took place in a mature aspen forest in Prince Albert National Park, Saskatchewan, Canada. The aspen trees were 21.5 m high with a 2–3 m high hazelnut understory. The objectives were: (1) to compare the radiation regime...
A scheme for scaling leaf boundary layer conductances ( b b ) to tree crowns was developed for Azadirachta indica A. Juss. trees in windbreaks in the Sahel. This scheme was derived from measurements of g b , made with heated leaf-replica pairs mounted in the crowns of windbreak trees, and values...
Windbreaks are openly exposed to turbulent motions in the atmosphere because they are taller than adjacent crops and usually only one or two trees in width. Transpiration by trees in windbreaks, consequently, can be expected to deviate substantially from the equilibrium rate as a result of...
Many types of analysis require rainfall data, which must often be generated to overcome limitations in the historical record. The ability to model outlying rainfall years satisfactorily is particularly important in risk studies. We describe a rainfall generator with this ability, based on a...
The diurnal leaf orientation behaviour of row-planted cotton plants ( Gossypium hirsutum L. cv. ‘DES 119’) and its relationship to sunlit leaf area distribution at three stages of development were studied in the field. Electromagnetic digitizing was used for plant geometrical structure...
