The purpose of the present article is to investigate if there exist any such set of temporal stable patterns in temporal series of meteorological variables studying series of air temperature, wind speed and direction an atmospheric pressure in a period with meteorological conditions involving nocturnal inversion of air temperature in Allen, Río Negro, Argentina. Our conjecture is that there exi...

Abstract. The Brewer ozone spectrophotometer (the Brewer) was designed at Environment and Climate Change Canada (ECCC) in the 1970s to make accurate automated total column measurements. Since 1980s, instrument has become a World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) standard monitoring instrument. Now, more than 230 Brewers have been produced. To assure quality of meas...

background: industrialization and urbanization had a devastating impact on public health and caused an increase in health related morbidity and mortality. in fact, asthma is a chronic condition which is considered as one of the significant challenges of public health. in this study, we investigated the association of air pollution and weather conditions with excess emergency ward admissions of ...

BACKGROUND Changes in meteorological parameters have been associated with cardiovascular mortality and stroke. The high incidence of stroke in Portugal may be modelled by short- or long-term weather changes whose effect may be different across stroke types and severity. METHODS Data include all patients with a first-ever-in-a-lifetime stroke registered in a population of 86,023 residents in t...

The 2.2 version of the Weather Research and Forecasting (WRF) model has been used to investigate the atmospheric behavior on extreme weather events, such as the passage of the Gordon extra-tropical depression over the Iberian Peninsula, on September 21st, 2006. The study of this particular event has been conducted using two nested domains, with 15 and 3 km resolution, respectively, and its resu...

This study aims to develop a forecasting model by assessing the weather variability associated with seasonal fluctuation of Aedes aegypti oviposition dynamic at a city level in Orán, in northwestern Argentina. Oviposition dynamics were assessed by weekly monitoring of 90 ovitraps in the urban area during 2005-2007. Correlations were performed between the number of eggs collected weekly and weat...

Large archives of historical meteorological data offer novel opportunities for weather forecasting and meteorological research. However, effective exploitation of such an archive is impeded by the logistics of managing large volumes of data and the difficulty of identifying relevant data. MetVUW Workbench is a case retriever that allows meteorologists to identify relevant past weather situation...

In the paper we discuss the analysis of multidimensional data. We consider the relationship between them using a special fuzzy number form. Calculations are kept on set of actual and historical meteorological data. Our model using to forecast pollution concentrations is important in today because pollutions have very big influence on our life in particular pollutions PM10 (particulate matter le...

This paper reports on a rough set approach to classifying meteorological volumetric radar data used to detect storm events responsible for summer severe weather. The classification of storm cells is a difficult problem due to the complex evolution of storm cells, the high dimensionality of the weather data, and the imprecision and incompleteness of the data. A rough set approach is used to clas...

Abstract A range of oxygenated volatile organic compounds (OVOCs) are present in the atmosphere as a result direct emissions and products atmospheric oxidation. Long-term measurements important to understand changes these emission sources oxidation processes. Accurate stable traceable gaseous primary reference materials needed underpin rigorous quality assurance control at monitoring stations s...
