This Lessons from History article about the wind-chill index (WCI) explores historical polar and meteorologic literature relevant to topic presents unpublished work 1939. Geographer Paul Siple (1908–1968) was a 6-time Antarctic explorer scientist who invented named WCI in his doctoral dissertation at Clark University. Charles Passel (1915–2002) performed studies Antarctica 1940 that led publica...

Precise spatial information on soil properties in plantation forests is needed to improve nutrient management and sustain productivity. Soil nitrogen, phosphorus, potassium, organic matter, carbon boron are important determinants indicators of fertility quality. Particularly forests, these highly variable space time. In this study, soils were sampled from three forest sites a dry sub-humid regi...

With the acceleration of urbanization, waterlogging has become an increasingly serious issue. Road waterlogging has a great influence on residents' travel and traffic safety. Thus, evaluation of residents' travel difficulties caused by rainstorm waterlogging disasters is of great significance for their travel safety and emergency shelter needs. This study investigated urban rainstorm waterloggi...

Flow past a single-line arrangement of evenly-spaced row trees, in an open territory, was numerically simulated under the action boundary-layer type oncoming flow, with strength “strong breeze”, based on Beaufort scale. By selecting Koelreuteria henryi as demonstrated tree species, spatial wind speed variations behind trees at pedestrian level, various heights and spaces, were analyzed to inves...

Wind-induced turbulence can strongly impact ecological processes in shallow lake ecosystems. The creation of shelter against wind be expected to affect both primary producers and herbivores aquatic food webs. Shelter may benefit particular more than others by changing relative resource availabilities for different producers. Herbivore community compositions affected either directly or indirectl...

PURPOSE We examined the cross-sectional and longitudinal association between social network characteristics and street youths' shelter use, a determinant of health outcomes for homeless youth. METHODS We analyzed interview data from 138 street youth recruited through venue-based sampling in San Francisco, to assess the cross-sectional relationship between shelter use in youths' social network...

Environmental temperatures considerably affect the reptilian ability for thermoregulation and harsh climatic conditions may impose a highly effective body temperature regulation to lizards. Such demanding conditions are more common to extreme mainland habitats (e.g. deserts or mountains). To the contrary, islands have more benign climate conditions thanks to the thermal buffering effect of the ...
