The occurrence of non-fatal acute coronary syndromes (ACS) is examined in relation with the local bioclimatic conditions in the Ierapetra area, in the southernmost part of Crete Island, Greece, during the period 2004-2007. Daily ACS counts and corresponding meteorological parameters, such as maximum and minimum air temperature, relative humidity, wind speed and cloudiness, were analyzed. Beside...

The impact of airborne pollen to human health has been recognized as being important, while several studies are suggesting that the synergy between high pollen concentrations and air pollutants may induce and exacerbate allergic reactions, thus affecting overall quality of life of citizens. In this paper, the detailed pollen, air quality and meteorological data for the years 2006 and 2007, for ...

background: the aim of study was to measure particle matter concentration (pm 1, pm 2.5 and pm 10 ) during normal, semi-dust and dust-event days. the impacts of some meteorological factors on particle matter concentrations were also investigated. methods: samples were collected by grimm aerosol technik (gmbh model 1/108 germany) from november 2011 to may 2012. temperature, humidity, wind speed ...

Wind farms are producing a considerable portion of the world renewable energy. Since the output power of any wind farm is highly dependent on the wind speed, the power extracted from a wind park is not always a constant value. In order to have a non-disruptive supply of electricity, it is important to have a good scheduling and forecasting system for the energy output of any wind park. In this ...

To reveal the multivariate relationships between man-made and meteorological factors on dust storm frequency, the LUCC data, NDVI remote sensing data and meteorological data for the period of 1983-2013 were combined with dust storm frequency data, and the possible impacts of meteorological and anthropogenic factors on dust storm frequency were analyzed by using regression analysis and PCA (Prin...

The air pollution problem has been serious in Delhi due to the rapidly expanding economic, industrial and vehicular developments. It has significant influences on atmospheric visibility, whose degradation dominates in urban areas. Increased air pollution in urban area may lead to the atmospheric reactions, resulting into the formation of secondary pollutants similar to cloud the condensation pr...

Models to predict seasonal hydrogen sulfide (H2S) concentrations were constructed using neural networks. To this end, two types of generalized regression neural networks and radial basis function networks are considered and optimized. The input data for H2S were collected from August 2005 to Fall 2006 from a huge industrial complex located in Ansan City, Korea. Three types of seasonal groupings...

In recent years, wind power generation is rapidly gaining popularity due to the major concerns about the excessive emissions and global energy crisis. In addition, this kind of power systems have shown more security options than others. Due to the highly variable and intermittent nature of the wind energy, it is crucial to achieve higher accuracy of long-term wind speed forecasts for improving ...

In order to achieve the predicted speed, high accuracy, the use of simple purpose, forest fire prediction of the key issues is to choose the main predictors. Forest fire prediction involves many factors, some of which are stable factors such as climate, topography, forest characteristics; and some unstable factors, such as fuel moisture content, meteorological factors, and other sources of igni...
