Temperature is one of the most important climate variables that many economic and social plans related to its changes. Because of The importance of this issue, this study investigated the changes of it in the province Khuzestan. Meteorological data that used in this study is mean temperature in annual and seasonal timescale. The study area is Abadan, Ahwaz, Dezful and Omidiye stations. For anal...

global warming has brought about changes in meteorological variable time series. these changes, accompanied with serious human intervention in nature, has resulted in hydrological changes. so the effects can be tracked down by the trend of the time series. the purpose of this study is to analyze and compare the monthly and annual trends of temperature, precipitation as well as stream flow time ...

A feeding station is the area of forage a grazing animal can reach without moving its forefeet. Grazing behavior can be divided into residence within feeding stations (with bites as benefits) and movement between feeding stations (with steps as costs). However, relatively little information has been reported on how grazing animals modify their feeding station behavior seasonally and interannual...

Common practice suggests that the assessment of wind and solar energy resources is based on data obtained from existing weather stations operated by the national meteorological services and other public services. Usually, these stations are placed at populated locations (for example airports, ports, urban, rural and protected areas) to support weather analysis, forecasts and warnings, local wea...

Local studies aimed at assessing the impact of climate variability on crop yield at the individual farm level require the use of weather and climate data. These are often collected at points known as meteorological stations. In West Africa, meteorological stations are sparsely distributed and as a result, are often unable to satisfy the data requirements for such studies. One major problem aris...

Global solar radiation (GSR) is required in a large number of fields. Many parameterization schemes are developed to estimate it using routinely measured meteorological variables, since GSR is directly measured at a limited number of station...

Long-term (1961–1990) areal evapotranspiration (AE) has been modeled with the help of 210 stations of the Solar and Meteorological Surface Observation Network within the conterminous United States. Modeled AE, averaged over all stations, has shown an overall increase of about 2–3% in the period 1961–1990, both on an annual basis and over the warm season (May–September). The rate of increase has...

The paper presents a multi-agent system, AirQMAS, developed for air quality analysis at different stations from the Romanian national air quality monitoring network. The multi-agent system includes collaborative agents that work together in order to improve the overall efficiency of the system. Two types of agents are used: environmental agents and meteorological agents. The learning capability...

The Adriatic Sea meteotsunami research and warning network is described. The network is located in the middle Adriatic, an area where the most destructive of the Adriatic meteotsunamis (destructive tsunami-like sea level oscillations generated by air pressure oscillations) occur. The network consists of three microbarograph meteorological stations, and is supplemented by four permanent tidegaug...
