Spatial and temporal distribution of dust deposition rate (DDR) in Isfahan city and the influencing climatic parameters were studied. Dust samples were collected using glass trays placed on the roof of one-story buildings from 20 sites in Isfahan city for 12 months. Climatic data were obtained from Meteorological Organization and analyzed. The highest and the lowest amount of DDR in agreement w...
in the current investigation, evaporation and transpiration potential were also estimated by means of fao penman- monteith evapotranspiration estimation method and deviation from optimum percentage (dop) technique by climatic elements (min-max temperature, relative humidity, wind speed and radiation) during at least 10 years statistical period regarding sunflower phenological conditions in kurd...
Climate change sensitivities of subtropical cloud-topped marine boundary layers are analyzed using large-eddy simulation (LES) of three CGILS cases of well-mixed stratocumulus, cumulus under stratocumulus, and shallow cumulus cloud regimes, respectively. For each case, a steadily forced control simulation on a small horizontally doublyperiodic domain is run 10-20 days into quasi-steady state. T...
abstract evapotranspiration as one of the important elements in agriculture has a considerable role in water resource management. therefore, using a more exact estimation method is an essential step of agricultural development, especially in arid semi-arid area. in this research, in order to exact estimate of garlic evapotranspiration using lysimeteric data, an artificial neural network (ann) m...
Background and aims: lack of thermal comfort in outdoor environments, can cause disorders and diseases, negative impact on productivity and performance, and even can cause death. Therefore, it is important to evaluate it. Various indices and models have been used to assess the level of comfort of humans. In most evaluations has been tried to estimate the comfort level using meteorological data ...
Background & Aim: Particulate matters are of the most important air pollutants, particularly in large cities, having harmful effects on the human’s health and the environment. The present study aimed to investigate of the relationship between meteorological parameters with PM2.5 changes using AQI index in Mashhad from 2014 to 2016. Methods: This study is cross-sectional. Data related to concen...
BACKGROUND Asthma exacerbations attended in emergency departments show a marked seasonality in the paediatric age. This seasonal pattern can change from one population to another and the factors involved are poorly understood. OBJECTIVES To evaluate the association between meteorological factors and schooling with asthma exacerbations in children attended in the paediatric emergency departmen...
H2S, PM2.5, O3, NO2, SO2 and meteorological parameters such as temperature, relative humidity, precipitation, wind speed and wind direction were measured simultaneously in an eastern Croatian town called Slavonski Brod during the season winter/spring 2010. Emissions from the nearby cross-border (Bosnia and Herzegovina) oil refinery were identified as sources of temporary elevated concentrations...
