This paper presents results from a computational and laboratory investigation of wind flow fire spread over an isolated sloped-ridgeline laboratory-scale hill under various slopes with the blowing perpendicularly to ridgeline. The show two situations unexpected or unusual behaviour; one is lateral front windward face into down-ridge direction resulting strong near-surface component parallel oth...

Raindrop size distribution (DSD) over the complex terrain of Guangdong Province, southern China, was studied using six disdrometers operated by Meteorology Service during period 1 March 2018 to 30 August 2022 (~5 years). To analyze long-term DSD characteristics topography in three stations on windward side, Haifeng, Enping and Qingyuan, leeward Meixian, Luoding Xuwen, were utilized. The median ...

phylaxis, and especially those of the Royal Society Reports to the Malaria Committee, 1 have been struck by the absolute absence ol mention of" wind" as a very serious factor to contend with. Observations have been made on the flight ol the mosquito aud the utmost distance allowed is half mile. As several observers agree to this distance according to the observations they have made, the conclus...

Abstract The article is based on the theory of computational fluid dynamics. We qualitatively analyse difference between total pressure windward side and leeward by numerical method, compare wind environment around ground floor non-overhead courtyard building with same width height. distribution velocity field, field trace map fully overhead not completely are obtained. By introducing CFD simul...

Oblique collision between the Caribbean plate and Bahama Banks has lead an eastward migration of northern boundary by successive southward jumps major strike-slip faults. The Septentrional-Oriente Fault zone (SOFZ) defines present-day accommodating most escape plate. Here, we reevaluate complex history SOFZ along Windward Passage area easternmost region Cuba northwest Haiti. Based on seismic re...

Detailed investigation of two-dimensional roughness element influence on the flow behind three-dimensional was carried out. For first time studies were conducted windward side flying wing in range free-stream 7,2 – 20 m/s favourable gradient region elements. Secondary instability mechanisms disturbances leading to turbulence stage investigated. It shown that longitudinal structure forming grows...

The aerodynamic breakup of the droplet has been intensely studied in this paper. We aim to establish a unified relationship between dimensionless kinematic parameters such as displacement, spreading diameter, Weber number, time, and so on. characteristics acoustic levitated ethanol are experimentally investigated when exposed an air jet flow. phenomenons were recorded with high-speed camera. an...

The vegetation database CACTUS (registered in GIVD under SA-00-004) aims to bring together all plot-based relevés from the Dutch Caribbean Islands that are available literature, unpublished resources, and recent field surveys. currently contains 2,701 descriptions. is used for classification, investigate change over time, assist planning of surveys, as a source plant species distribution maps, ...

Introduction: Barchans are individual, mobile, crescentic shape dunes, the two horns of which face in the direction of movement. Generally they occur in areas of limited sand supply, with a low precipitation and vegetation cover, on planar surfaces and where winds are unimodal to narrowly bimodal. On Mars, the most common dune is transverse and within the barchan group there is a wide variety o...
