Abstract Background and Objective: Air pollution can harm humans and the environment. To reduce the effect of these parameters in the emissions of air pollutants known to the local topographical features and climatic conditions are factors. The purpose of this study, monthly and seasonal variations are contaminants and their relationship with meteorological parameters. Methods: the presen...
This paper presents the results of an investigation into the utility of remote sensing (RS) using meteorological satellites sensors and spatial interpolation (SI) of data from meteorological stations, for the prediction of spatial variation in monthly climate across continental Africa in 1990. Information from the Advanced Very High Resolution Radiometer (AVHRR) of the National Oceanic and Atmo...
We installed solar panels and digital meteorological equipments whose electrical power is supplied using PV on July 13, 2011. Then, the relationship between the electric power generation and the irradiation, air temperature, and wind velocity was investigated on a roof at a university. The electrical power generation, irradiation, air temperature, and wind velocity were monitored over two years...
Dengue and malaria are vector-borne diseases and major public health problems worldwide. Changes in climatic factors influence incidences of these diseases. The objective of this study was to investigate the relationship between vector-borne disease incidences and meteorological data, and hence to predict disease risk in a global outreach tourist setting. The retrospective data of dengue and ma...
BACKGROUND The evaluation of exposure to ambient temperatures in epidemiological studies has generally been based on records from meteorological stations which may not adequately represent local temperature variability. Here we propose a spatially explicit model to estimate local exposure to temperatures of large populations under various meteorological conditions based on satellite and meteoro...
The Internet has created new opportunities but also complexities in the operations and services of meteorological centres. Through exchange of meteorological data the Internet has introduced new methodologies and techniques for processing distributed meteorological data. Forecasters need to embrace massive technological innovations, new operating systems, and new types of information, tight dea...
The universal principle that an open system can be driven to a state far from equilibrium, or organized, by strong negative entropy flow from its surroundings has been validated in numerous fields from physics and chemistry to the life science. In this paper, entropy flows for a severe storm are calculated via the entropy flow formula using the National Centers for Environmental Prediction/Nati...

Interactive comment on “ Volcanic effects on climate : revisiting the mechanisms ” by H . - F . Graf
The paper addresses an important problem of mechanisms of sensitivity of highlatitude circulation with respect to volcanic forcing. The authors attempted to distinguish two major mechanisms based on reflection and refraction of planetary waves using analysis of NCEP data assimilation output for the period from 1958 to 2002. All previous data analyses were conducted using mostly surface data. Th...
