Dog Days Of Winter

Climatology of winter transition days for the contiguous USA , 1951 – 2007

In middle and high latitudes, climate change could impact the frequency and characteristics of frontal passages. Although transitions between air masses are significant features of the general circulation that influence human activities and other surface processes, they are much more difficult to objectively identify than single variables like temperature or even extreme events like fires, drou...

Characteristics of solar energy radiation on typical summer and winter days in

The energy received by solar collectors for power generation is limited to various conditions. The average data on solar irradiation are normally used to determine the potential of solar energy at any location. However, the variation of solar energy due to seasonal differences could affect the actual performance of the collectors, consequently leading to poorly justified system installations, w...

Warning: the short days of winter may be hazardous to your health.

Almost all living organisms have evolved biological rhythms linked to the day-night or light-dark cycles of the sun. The impact of such rhythms that follow the time of day and season of the year on a variety of physiological functions in humans has been recognized for a long time. The internal oscillator, or control station regulating the body’s circadian clock, is the suprachiasmatic nucleus (...

High-mortality days during the winter season: comparing meteorological conditions across 5 US cities.

While the relationship between weather and human health has been studied from various perspectives, this study examines an alternative method of analysis by examining weather conditions on specific high-mortality days during the winter season. These high-mortality days, by definition, represent days with dramatic increases in mortality and the days with the highest mortality. By focusing solely...
