The relative importance of various source regions on East Asian surface ozone
source regions East Asian surface ozone
2010/12/20
We estimated the source-receptor relationship for surface O3 in East Asia during the early 2000s using a method that tags O3 tracers according to their region of chemical production (tagged tracer met...
Magnetic Source Regions of Coronal Mass Ejections
Coronal mass ejection flare filament eruption
2010/9/16
The majority of flare activity arises in active regions which contain sunspots, while Coronal Mass Ejection (CME) activity can also originate from decaying active regions and even so-called quiet sola...
Helioseismic Ring Analysis of CME Source Regions
Sun coronal mass ejections oscillations magnetic field
2010/9/16
We apply the ring diagram technique to source regions of halo coronal mass ejections (CMEs) to study changes in acoustic mode parameters before, during, and after the onset of CMEs.We find that CME re...
Climatological aspects of the extreme European rainfall of August 2002 and a trajectory method for estimating the associated evaporative source regions
Climatological aspects the extreme European rainfall a trajectory method the associated evaporative source regions
2009/12/14
During the first half of August 2002, a sequence of extreme precipitation episodes affected many regions of central and southern Europe, culminating in one of the most severe flooding events ever expe...
High frequency ion sound waves associated with Langmuir waves in type III radio burst source regions
High frequency ion sound waves Langmuir waves type III radio burst source regions
2009/11/11
Short wavelength ion sound waves (2-4kHz) are detected in association with the Langmuir waves (~15-30kHz) in the source regions of several local type III radio bursts. They are most probably not due t...
Composition of Saharan dust and its possible source regions –a review
Saharan dust source identification composition
2011/11/8
The Sahara is the strongest source on earth for mineral dust, supplying up to 109 t per year of material to the atmosphere (about 50 % of the total mineral dust burden). Saharan dust is subject to lon...
IMPACTS OF CLIMATE FACTORS ON RUNOFF COEFFICIENTS IN THE SOURCE REGIONS OF THE YELLOW RIVER
water resources runoff coefficient precipitation streamflow baseflow baseflow coefficient
2009/10/12
In the 1990's, runoff at the Tangnaihai hydrologic station experienced a serious decrease which attracted considerable attention. Changes in temperature and rainfall would have an important impact on ...
Source regions of some persistent organic pollutants measured in the atmosphere at Birkenes, Norway
persistent organic pollutants atmosphere Birkenes Norway
2009/9/14
A key feature of POPs (Persistent Organic Pollutants) is their potential for long-range atmospheric transport. In order to better understand and predict atmospheric source-receptor relationships of PO...

In situ measurements of speciated atmospheric mercury and the identification of source regions in the Mexico City Metropolitan Area
speciated atmospheric mercury source regions Mexico City Metropolitan Area
2009/3/12
In order to expand the currently limited understanding of atmospheric mercury source-receptor relationships in the Mexico City Metropolitan Area, real time measurements of atmospheric mercury were mad...
The Role of Mesoscale Eddies in the Source Regions of the Agulhas Current
Role of Mesoscale Eddies Source Regions Agulhas Current
2008/7/22
A primitive equation model to study the dynamics of the Agulhas system has been developed. The model domain covers the South Atlantic and the south Indian Ocean with a resolution of ° in the Agulhas r...
Impact of land-cover and climate changes on runoff of the source regions of the Yellow River
2007/8/24
After dividing the source regions of the Yellow River into 38 sub-basins, the paper made use of the SWAT model to simulate streamflow with validation and calibration of the observed yearly...
Based on geographical and hydrological extents delimited, four principles are identified, as the bases for delineating the ranges of the source regions of the Yangtze and Yellow rivers in ...
