The amount of water held in individual wetland basins depends not only on local climate patterns but also on groundwater flow regime, soil permeability, and basin size. Most wetland basins in the northern prairies hold water in some years and are dry in others. To assess the potential effect of climate change on the number of wetland basins holding water in a given year, one must first determin...

[1] Shipboard radiosonde measurements revealed a persistent temperature inversion layer with a thickness of 200 m at 12–13 km in a nonconvective region over the tropical eastern Pacific, along 2 N, in September 1999. Simultaneous relative humidity measurements indicated that the thin inversion layer was located at the top of a very wet layer with a thickness of 3–4 km, which was found to origin...

Seasonal acclimatisation of thermal tolerance, evaporative water loss and metabolic rate, along with regulation of the hive environment, are key ways whereby hive-based social insects mediate climatic challenges throughout the year, but the relative importance of these traits remains poorly understood. Here, we examined seasonal variation in metabolic rate and evaporative water loss of worker b...

The present study aimed to investigate the applicability of Universal Thermal Climate Index (UTCI) as an innovative and science-based index in public health researches, in occupational heat stress assessment. All indoor and outdoor workers (200 people) of Brick industries of Shahroud, Iran participated in the research. First, the environmental variables such as air temperature, wet-bulb tempera...

"VOC emissions from beef feedlot pen surfaces as affected by within-pen location, moisture and temperature" (2015). Air quality Feedlot Gas chromatography Odour VOC A laboratory study was conducted to evaluate the effects of pen location, moisture, and temperature on emissions of volatile organic compounds (VOC) from surface materials obtained from feedlot pens where beef cattle were fed a diet...

Cape fur seal (Arctocephalus pusillus) pups spend the first weeks of life exclusively or mainly ashore. They are exposed to intense solar radiation and high temperatures for long time periods, which results in temperatures up to at least 80°C on their black natal coat. To test the hypothesis that the natal coat has a crucial function in coping with these extreme conditions, we investigated the ...

OBJECTIVES This report describes physiological and behavioural mechanisms behind the control of body temperature and thermal comfort during competitive singles tennis. METHODS Thermoregulatory responses and workload were observed during "best of three sets" tennis matches among 25 players. In total, 94 matches were played in ambient temperatures ranging from 14.5 to 38.4 degrees C. The therma...

Although the wet season in the tropical Amazon (108N–208S) at any one place and in any one year is initiated rapidly by synoptic systems, large-scale thermodynamic conditions modulate the frequency and intensity of these synoptic systems and hence control the climatology of the wet season. In this study, the satellite radiances, radiosondes, and assimilation data of the atmosphere are analyzed ...

For controlled environment agriculture (CEA) related facility planning and design, weather information for the specific location are required for the estimation of heating/cooling loads and design of environmental control components and systems. Summer/Winter design temperature and degree day were the traditional methods used by the engineers to estimate the annual cooling/heating load. Weather...
