numerous studies yet have been carried out on downscaling of the large-scale climate data usingboth dynamical and statistical methods to investigate the hydrological and meteorological impacts of climatechange on different parts of the world. this study was also conducted to investigate the capability of feedforwardneural network with error back-propagation algorithm to downscale the provincial...

Climate is constantly changing, and the signals indicating that changes are occurring can be evaluated over a range of temporal and spatial scales. Climate can be viewed as an integration of complex weather conditions averaged over a significant area of the Earth (typically on the order of 100 km2 or more), expressed in terms of both the mean of weather represented by properties such as tempera...

Grasslands and riparian forests in southeastern South Dakota have been greatly reduced since historical times, primarily due to conversion to row-crop agriculture. Common Nighthawk (Chordeiles minor) nesting habitat includes grasslands, open woodlands and urban rooftops, but nesting sites in southeastern South Dakota are confined to rooftops, as natural nesting habitat is limited. Nighthawks ne...

ozone concentration in metropolitan areas frequently exceed regulatory standards now. since it is harmful on human health and environment, its modeling and visualization are of vital important. modeling and prediction of ozone is required by urban managers to control and prevent its effects. in this paper, important parameters influencing the hourly ozone concentration are estimated by using da...

Several investigations have shown that enhanced mixing brought about by wind turbines alters near-surface meteorological conditions within and downstream of a farm. When scalar parameters been considered, the focus has most often centered on temperature changes. A subset these works also considered humidity to various extents. These limited are complemented just few studies dedicated analyzing ...

During the week of 7-14 March 2006, observations of winds and relative humidity were taken at various points along the mountain at Storm Peaks Laboratory in Steamboat Springs, CO. These observations were used to determine the relationship between slope flow and relative humidity. Slope flow is defined as the dot product of the wind vector and the gradient in elevation. The charts show details a...

[1] We show that a simple model of pan evaporation (‘‘PenPan’’) can be used to analyze monthly mean output from a global climate model (GCM). PenPan is based on a modified version of Penman’s potential evapotranspiration equation. Very good agreement is obtained with observed annual pan evaporation for Australian sites when PenPan is forced by surface observations of radiation, wind speed, humi...

Alternaria and Cladosporium spores belong to the most frequent and allergenic particles in bioaerosol in the temperate climate. The investigation of Alternaria and Cladosporium spore concentrations was performed in two cities in Poland, Szczecin and Cracow, in 2004-2013. The meteorological parameters taken to assess their impact on fungal spores were average, maximum and minimum temperature, re...
