This study analyses potential associations between day-to-day variations in common ragweed pollen counts in the southern Hungarian district of Szeged and meteorological variables using adapted factor analysis. The database includes ten years (1997-2006) worth of data on daily common ragweed pollen ratios (value on the given day per value on the day before) and daily differences (value on the gi...
After considering the observed long-term trends in average monthly temperatures distribution in Moscow, the authors evaluated how acute mortality responded to changes in daily average, minimum and maximum temperatures throughout the year, and identified vulnerable population groups, by age and causes of death. A plot of the basic mortality-temperature relationship indicated that this relationsh...
The short-term relationship between winter temperatures and cardiac disease mortality in Cape Town was investigated for the period 1978-1985. The mortality data were stratified according to age (0-4 years, 5-59 years, 60 years and older), while the temperature data comprised daily maximum and minimum temperatures at Cape Town International Airport. The analyses identified a strong lagged relati...
Daily meteorological observations have been made at the Brera astronomical observatory in Milan since 1763. Even if the data have always been collected at this observatory, the Milan series are far from being homogeneous as several changes were made to instruments, station location and observation methods. Within this context, the purpose of the paper is to discuss data homogenisation. Homogeni...
Using daily minimum air-temperature (Tmin) data from the state of Illinois, the dates of spring and fall freezes – and the resulting growing-season length – are examined for trends during the period 1906–1997. Of the stations in the Daily Historical Climate Network, most show trends toward earlier spring freezes; however, trends in fall freezes are not consistent over the station network. Altho...
BACKGROUND Few studies have examined variation in the associations between heat waves and mortality in an international context. OBJECTIVES We aimed to systematically examine the impacts of heat waves on mortality with lag effects internationally. METHODS We collected daily data of temperature and mortality from 400 communities in 18 countries/regions and defined 12 types of heat waves by c...
Effects of climate change are a critical and globally accepted phenomenon gradually becoming inevitable catching the attention policymakers around world. Temperature is principal climatic factor defined as degree or intensity heat causing huge consequences on human beings’ lives. This paper suggests some stochastic approaches to do an analysis Karachi region’s daily minimum extreme temperature ...
