Regional Climate Modeling: An Overview

Regional climate models are useful tools for regional climate research. They are especially helpful for studying the effects of topography, coastlines, and other complex landsurface properties on regional climate and for simulating these effects realistically. Although regional climate modeling started more than ten years ago, improvements in model physics and performance have been slow. There ...

Modeling the effects of climate change on the distribution of Acanthalburnus urmianus (Günther, 1899) in Urmia lake basin rivers

According to the reports of the International Panel Climate Change (IPCC) there is no doubt about climate change occurring. All ecosystems on the earth have being concerned by the effects of climate change. Urmia lake basin and its rivers exposed to numerous anthropogenic stressors such as hydrological, morphological, connectivity and water quality pressures. The main objective of this study is...

Modeling the discharge of rivers in selected watersheds of Guilan province during climate change

   In this essay, we investigated the effects of climate change on the rivers of selected basins of Guilan province, one of the northern provinces of Iran for the period 2020 to 2050 under three climate scenarios: RCP2.6, RCP4.5, RCP8.5. For this purpose, rainfall and temperature data from 45 climate data stations and 20 hydrometric stations from 1983 to 2013 were used. The average precipitatio...

Understanding the Role of Job Stress in Safety Climate in a Dairy Industry using Structural Equation Modeling

Background and purpose: The safety climate refers to employees’ perception of safety which can be affected by job-related stress in the workplace. This study aimed to assess the safety climate and investigate the relationship between job stress factors and safety climate dimensions in a dairy industry. Materials and Methods: This was a cross-sectional study. The data was collected using two se...

Simulating the Influence of Greenhouse Gases on the Climate of West Africa

The response of climate to perturbations in GHGs is location dependent. Six experiments: control (CTRL); double CH4; double CO2; double N2O; halved CFC11 and halved CFC12 were carried out to reveal the local area response to different GHGs levels in the atmosphere over West Africa. Double CH4, CO2 and N2O generally induce wetness but they also induce localized dryness at the hilly and mountaino...
