Trends and emissions of six perfluorocarbons in the Northern Hemisphere and Southern Hemisphere [PDF]
Perfluorocarbons (PFCs) are potent greenhouse gases with global warming potentials up to several thousand times greater than CO2 on a 100-year time horizon. The lack of any significant sinks for PFCs means that they have long atmospheric lifetimes of the

DEVELOPMENT OF 23 CYCLES ACTIVITY IN NORTHERN AND SOUTHERN HEMISPHERES OF THE SUN
On an example of the 23rd cycle of solar activity the basic properties of its development in northern and southern hemispheres were researched (daily values of Wolf Sunspot Number - W, the daily values of Sun spots areas - Sp and daily values of flare ...

A Climatology of Northern Hemisphere Blocking [PDF]
Abstract In this paper a 55-yr (1948–2002) Northern Hemisphere blocking climatology is presented. Traditional blocking indices and methodologies are revised and a new blocking detection method is designed. This algorithm detects blocked flows and provides for a better characterization of blocking events with additional information on ...

Cetacean morbillivirus in Northern and Southern Hemispheres [PDF]
In the last 25 years, at least 10 dramatic morbilliviral epidemics have occurred among free-ranging pinniped and cetacean species and populations worldwide. The origin(s) of the new Morbillivirus genus members causing these mass mortality events, along with the reason(s) behind their “sudden” appearance among wild aquatic mammals, are still unknown (Di

Seasonality of Kawasaki disease: a global perspective. [PDF]
Understanding global seasonal patterns of Kawasaki disease (KD) may provide insight into the etiology of this vasculitis that is now the most common cause of acquired heart disease in children in developed countries worldwide.Data from 1970-2012 from 25 ...

A tropical mechanism for Northern Hemisphere deglaciation [PDF]
We investigate the role of the tropics in the melting and reforming of the Laurentide ice sheet on glacial timescales using an atmospheric general circulation model. It is found that warming of tropical sea surface temperatures (SSTs) from glacial boundary conditions, as observed at the end of glacial periods, causes a large increase in summer ...
