The plastic effect is historically used to denote various forms of stereopsis. The vivid impression of depth often associated with binocular stereopsis can also be achieved in other ways, for example, using a synopter. Accounts of this go back over a hundred years. These ways of viewing all aim to diminish sensorial evidence that the picture is physically flat. Although various viewing modes ha...

Pollution levels and the effect of air pollution on human health can be modified by synoptic weather type and aeroallergens. We investigated the effect modification of aeroallergens on the association between CO, O3, NO2, SO2, PM10 and PM2.5 and asthma hospitalisation rates in seven synoptic weather types using single air pollutant models, adjusted for the effect of aeroallergens and stratified...

Previous studies have demonstrated the key role of baroclinicity and thus the isentropic slope in determining the climatological-mean distribution of the tropospheric eddy fluxes of heat. Here the authors examine the role of variability in the isentropic slope in driving variations in the tropospheric eddy fluxes of heat about their long-term mean during Northern Hemisphere winter. On month-to-...

abstract drought is a natural creeping event that starts due to lower moisture compared to normal condition. this phenomenon impacts all aspects of human activities. however there is neither any detailed definition nor a general and proper index for drought monitoring. in this study, fuzzy logic has been applied to deal with inherent uncertainties of the real world data. we presented a fuzzy mo...

An adaptation technique based on the synoptic atmospheric circulation to forecast local precipitation, namely the analogue method, has been implemented for the western Swiss Alps. During the calibration procedure, relevance maps were established for the geopotential height data. These maps highlight the locations were the synoptic circulation was found of interest for the precipitation forecast...

The loess hilly-gully region is a focus region of the "Grain for Green" program in China. Drought is the main problem in the study region. Precipitation and temperature are two indicators that directly characterize climatic drought. A thorough analysis of the precipitation, temperature and drought characteristics of the loess hilly-gully region can clarify the current water and heat conditions ...

in this research, elemental and chemical characteristics of atmospheric dust particulates including major and trace elements in two synoptic meteorological stations (abadan and urmia cities) during dust events and ambient periods have been evaluated. results showed that during dust events to ambient periods in both stations, major elements including ca, mg, al and trace elements comprised p and...

The jet stream has wide importance in analyzing synoptic maps because it correlates with other meteorological factors, so the study attempted to sub-tropical (SJS) and shows variation ranges of atmospheric variables on its path depending highly accurate obtained from (University Wyoming), tried show correlation surface temperature Baghdad city data given automatic weather station that located a...

Abstract This study is the first that worked on temporal and spatial distributions of annual rainfall (Pyear) maximum 24-h (Pmax24h) in Semnan province. For this purpose, different statistical were used to estimate Pyear Pmax24h Six synoptic stations across province studied all had complete data. Different return periods studied. The goodness fit test for showed about 67% follow Generalized Par...
