abstract climate variability empowers critical consequences on sustainability of soil and water resources. in this paper the trend of annual and seasonal time scale of temperature (minimum, maximum, average), relative humidity (minimum, maximum, average), precipitation, wind speed, extreme events, cloudiness, reference evapotranspiration employing mann-kendall and least square errors were studi...

BACKGROUND The traditional nasal cannula with bubble humidifier is limited to a maximum flow of 6 L/min to minimize the risk of complications. We conducted a bench study of 2 new Food and Drug Administration-approved nasal cannula/humidifier products designed to deliver at flows> 6 L/min. METHODS Using a digital psychrometer we measured the relative humidity and temperature of delivered gas f...

Climatic conditions affect the performance of photovoltaic panels. In this study, the effect of ambient air temperature and relative humidity on the performance parameters of two types of silicon photovoltaic solar panels, including mono-crystalline silicon (mc-Si) and polycrystalline silicon (pc-Si), were studied in the laboratory scale. The experiments were carried out by the performance test...

[1] Simulations of warming climates with coupled climate models exhibit strong land-ocean contrasts in changes in surface temperature and relative humidity, but little land-ocean contrast in changes in equivalent potential temperature. A theory that assumes equal changes in equivalent potential temperature over land and ocean captures the simulated land-ocean warming contrast in the tropics if ...

In this study, the levels of meteorological parameters like maximum temperature (°F), relative minimum humidity (%), dew point wind speed (mph), rainfall (in), and air pressure (in) were analyzed for all three COVID-19 pandemic waves in NCT Delhi, India. After doing statistical analysis, results showed that only a few parameters, (maximum, minimum, relative), point, humidity, pressure, linked t...

The objective of this study was to evaluate the effects of relative humidity, light management, minimum ventilation rates, CO2 enrichment and canopy size on water consumption in three different greenhouse systems (conventional, open heat pump, and confined heat pump) in winter, spring, and summer months. Using different relative humidity set points resulted in almost the same relative humidity ...

Plants of the Urticaceae family can develop into a pest on soils enriched with nitrogen. Urticaceae pollen is a biohazard because it elicits severe pollinosis. Pollen grains were sampled by using a Lanzoni seven-day-recording trap from February 1995-December 2000 in the atmosphere of the city of Ponferrada (Leon, North Western Spain). The Spearman test was used to analyse the statistical correl...
