Daily weather conditions for an entire city are usually represented by a single weather station, often located at a nearby airport. This resolution of atmospheric data fails to recognize the microscale climatic variability associated with land use decisions across and within urban neighborhoods. This study uses heat index, a measure of the combined effects of temperature and humidity, to assess...

BACKGROUND Epistaxis is one of the commonest ENT emergencies and is experienced by up to 60% of people in their lifetime, with 6% requiring medical attention. The objective of the study was to determine the frequency of primary epistaxis and its relationship with temperature and relative humidity. METHODS This cross sectional study included 460 patients with epistaxis attending the ENT Depart...

[1] The surface of maximum wind (SMW) is used as a frame for examining spatial and temporal variability in the vertical position of fast upper tropospheric winds over the Northern Hemisphere during winter. At a given observation time in a gridded data set, the SMW is defined as the surface passing through the fastest analyzed wind above each grid node, with a vertical search domain restricted t...

tourism is an element depends on climate so that suitable climate and weather forecast in the destination is an attractive factor for tourists. in this research we used 9 synoptic stations data and tci index of lorestan province for comfort assessment of the province .this index use 7 climatic factors includes: rainfall, temperature, mean and minimum relative humidity, maximum temperature, dail...

Weekly cycles of meteorological parameters have been found in many regions around the world; however, the phase and magnitude of these cycles vary greatly from regions and seasons. Based on the NCEP/DOE reanalysis data and the daily surface station observation data from 1980 to 2009 in Beijing and surrounding areas, the weekend effect of aerosol concentration, precipitation and several other me...

[1] Surface air temperature measurements from meteorological stations on the Tibetan Plateau are compared to 2-m temperatures from the European Centre for MediumRange Weather Forecasts (ECMWF) reanalysis (ERA-40) to assess the accuracy of this reanalysis product. We focus on ERA-40 grid cells containing at least four stations. The reanalysis temperatures are consistently lower, by as much as 7 ...

accurate estimation of evaporation is important for design, planning and operation of water systems. in arid zones where water resources are scarce, the estimation of this loss becomes more interesting in the planning and management of irrigation practices. this paper investigates the ability of artificial neural networks (anns) technique to improve the accuracy of daily evaporation estimation....

a precise estimation of water consumption throughout a crop's growth season and of the amount of water consumed in each growth stage may play an important role in water resources management, integrated water and soil management, and proper irrigation scheduling. in a greenhouse, this faces with the conditions specific to this environment. this study was conducted to propose a model to make an a...
