BACKGROUND: Microbial quality of drinking water is very important in animal health. OBJECTIVES: The present survey was conducted to evaluate the microbial quality of cows' drinking water in dairy farms in Mashhad suburb, Iran, to find out defects in this field. METHODS: Water samples were taken from 30 farms and 4 sites including: Water tanks,  inlet and outlet  of bovine drinking troughs and c...

BACKGROUND Synoptic circulation patterns (large-scale tropospheric motion systems) affect air pollution and, potentially, air-pollution-morbidity associations. We evaluated the effect of synoptic circulation patterns (air masses) on the association between ozone and hospital admissions for asthma and myocardial infarction (MI) among adults in North Carolina. METHODS Daily surface meteorology ...

This article determines the atmospheric situation for 53 days where any weather station in Balearic Islands detected torrential rain (equal to or above 200 mm a single day) during period 1941–2010. To do this, synoptic charts each day were analysed, classifying them accordance with types established by Martín Vide (1984) and, addition, through automatic classifications from Jenkinson and Collis...

The study aims to analyse the weather conditions and upper elements associated with wet year 2002/2003, dry 2007/2008 in Jordan for months from November March, by using amounts of precipitation rainy days each year, analyzing synoptic maps at a pressure level (500hpa) determine direction axes cold troughs warm ridges extent their correlation prevalence humidity drought conditions. Tephigram cha...

The present work aims at examining the association of nighttime temperature inversions and synoptic-scale circulation in the Athens basin. Temperature inversions have a direct impact in the diffusion and transport of pollutants, a fact that highlights the importance of investigating their cause effect relationship. For this purpose, randiosonde measurements from the upper-air station in Hellini...

Abstract. Gaining a holistic understanding of extreme weather, from its physical drivers to impacts on society and ecosystems, is key supporting future risk reduction preparedness measures. Here, we provide an overview the state art, knowledge gaps open questions in study weather events over vulnerable eastern Mediterranean. This region situated transition zone between subtropical mid-latitude ...

in order to determine the synoptic pattern of heavy and extreme precipitations on the southern coast of the caspian sea, precipitation characteristics of the caspian region were investigated by the use of eight synoptic stations data. considering the percentage thresholds, the days with heavy and extreme precipitations were determined for a 10 year period (1994-2003). since more than 75% of day...
