Mosquito populations are sensitive to long-term variations in climate and short-term variations in weather. Mosquito abundance is a key determinant of outbreaks of mosquito-borne diseases, such as West Nile virus (WNV). In this work, the short-term impact of weather conditions (temperature and precipitation) on Culex pipiens L.-Culex restuans Theobald mosquito abundance in Peel Region, Ontario,...

OBJECTIVE To emphasize the effect of weather on the occurrence of the first episode of Schizophrenia. METHODS The relationship between weather and the first episode of schizophrenia was investigated at Ibn Sina Psychiatric Hospital, Damascus, Syria, from 1997 to 1999. RESULTS Schizophrenia in developing countries affects men at a higher rate than women. The highest rates are found in lower ...

The ever-increasing demand for accuracy of weather forecasting and understanding of weather phenomena requires new weather observation methods. Earth observation in the microwave regions can provide important data on moisture and temperature distributions in the atmosphere, even within cloud formations where such observations are not achievable in the visible or infrared spectrum due to occlusion.

This paper proposes and implements an equilibrium valuation framework for weather derivatives. We generalize the Lucas model of 1978 to include the weather as a fundamental variable in the economy. The model is specialized to temperature derivatives. Temperature behavior for the period of 1979-1989 is closely studied for ̄ve major cities in the U.S., and a model is proposed for the daily temper...

Weather factors are widely studied for their effects on indicating dengue incidence trends. However, these studies have been limited due to the complex epidemiology of dengue, which involves dynamic interplay of multiple factors such as herd immunity within a population, distinct serotypes of the virus, environmental factors and intervention programs. In this study, we investigate the impact of...

Sex differences in habitat use (habitat segregation) are widespread in sexually dimorphic ungulates. A possible cause is that males are more sensitive to weather than females, leading to sex differences in sheltering behaviour (the 'weather sensitivity hypothesis'). However, this hypothesis has never been tested. We considered the allometric rates of net energy gain during times of cold weather...

BACKGROUND Weather and climate changes are associated with a number of immediate and long-term impacts on human health that occur directly or indirectly, through mediating variables. Few studies to date have established the empirical relationship between monthly weather and mortality in sub-Saharan Africa. OBJECTIVES The objectives of this study were to assess the association between monthly ...

BACKGROUND The time distribution of injuries is not random. To assess the potential impact of weather and the phase of the moon on accidents, adjustment for known periodic and nonperiodic factors may be important. We compared the incidence of injuries with quantitative and qualitative weather variables as well as the lunar cycle, after correction for calendar and holiday-related factors. METH...
