Survey of advection of cold waves in Iran is the main aim of this study. In this regard, 45 synoptic stations were employed and studied. In order to investigate the thermal advection of cold waves, 1000, 850, 700 and 500 hp levels were reviewed and analyzed. Results indicated that cold waves in Iran most affected thermal advection caused by Tibet- Siberia, Siberias integrated Turkmenistan high-...

concrete labyrinths of the new social work depart-ments?where the central heating automatically goes on on October 1st and automatically goes off on April 1st, whatever the weather?the filing clerks excitedly cried: 'Isn't it amazing to have the windows open in February!' Nervous daffodils appeared on the typists' desks. It was a mild winter. Of course there were one or two contretemps. During ...

Artificial night lighting is expanding globally, but its ecological consequences remain little understood. Animals often use changes in day length as a cue to time seasonal behaviour. Artificial night lighting may influence the perception of day length, and may thus affect both circadian and circannual rhythms. Over a 3.5 month period, from winter to breeding, we recorded daily singing activity...

—Weekly reports of the abundance of the Argentine ant, Linepithema humile, in 69 households for 18 mo (1/98–7/99) in the San Francisco Bay Area in northern California were compared with weather data. Ant abundance inside homes was highest in cold rainy weather, and there was a second smaller peak of ant abundance in hot dry weather. Pesticide use in the home decreased ant abundance, from one we...

Interactions between parasites and environmental factors have been implicated in the loss of managed Western honey bee (=HB, Apis mellifera) colonies. Although laboratory data suggest that cold temperature may limit the spread of Nosema ceranae, an invasive species and now ubiquitous endoparasite of Western HBs, the impact of weather conditions on the distribution of this microsporidian in the ...

In addition to N load, cold weather nitrification is an important consideration for stabilized performance of biological processes applied to continuous animal production systems. A winter simulation experiment was conducted in the laboratory to evaluate performance of immobilized bacteria for treatment of swine wastewater under cold weather conditions. Bench fluidized reactors (1.2 L) containi...

BACKGROUND Research in mainly developed countries has shown that some changes in weather are associated with increased mortality. However, due to the lack of accessible data, few studies have examined such effects of weather on mortality, particularly in rural regions in developing countries. OBJECTIVE In this study, we aimed to investigate the relationship between temperature and rainfall wi...

It is well known that deaths from myocardial and cerebral infarction occur more frequently in the winter months and cold weather than in the summer (Rose, 1966; Rogot and Blackwelder, 1970; Ohno, 1969; Ohno et al., 1970). The death rates from both conditions are highly correlated with air temperature but it is argued by some (Anderson and le Riche, 1970) that the association is indirect and ari...

BACKGROUND There is an assumption that baseball athletes who reside in warm-weather climates experience larger magnitude adaptations in throwing shoulder motion and strength compared with their peers who reside in cold-weather climates. HYPOTHESES (1) The warm-weather climate (WWC) group would exhibit more pronounced shoulder motion and strength adaptations than the cold-weather climate (CWC)...
