A Climatology of Northern Hemisphere Blocking [PDF]

Journal of Climate, 2006
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]

Frontiers in Microbiology, 2014
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

High-resolution record of Northern Hemisphere climate extending into the last interglacial period [PDF]

, 2004
Two deep ice cores from central Greenland, drilled in the 1990s, have played a key role in climate reconstructions of the Northern Hemisphere, but the oldest sections of the cores were disturbed in chronology owing to ice folding near the bedrock.

Implications of changes in the Northern Hemisphere circulation for the detection of anthropogenic climate change [PDF]

, 2000
The first principal component of Northern Hemisphere sea level pressure, known as the Arctic Oscillation (AO) index, has increased significantly in recent winters, and this change is associated with ∼30% of Northern Hemisphere January–March warming.

Marine‐Calibrated Chronology of Southern Laurentide Ice Sheet Advance and Retreat: ∼2,000‐Year Cycles Paced by Meltwater–Climate Feedback

Geophysical Research Letters, 2023
Climatic warming following the Last Glacial Maximum caused the southern Laurentide Ice Sheet (LIS) to begin ∼2,000‐year cycles of retreat and readvance whose cause remains ambiguous.

Objective determination of the extratropical transition of tropical cyclones in the Northern Hemisphere [PDF]

, 2015
Extratropical transition (ET) has eluded objective identification since the realisation of its existence in the 1970s. Recent advances in numerical, computational models have provided data of higher resolution than previously available.

Trends and emissions of six perfluorocarbons in the Northern Hemisphere and Southern Hemisphere [PDF]

Atmospheric Chemistry and Physics, 2020
Perfluorocarbons (PFCs) are potent greenhouse gases with global warming potentials up to several thousand times greater than CO 2 on a 100-year time horizon. The lack of any significant sinks for PFCs means that they have long atmospheric lifetimes of the order of thousands of years ...

DEVELOPMENT OF 23 CYCLES ACTIVITY IN NORTHERN AND SOUTHERN HEMISPHERES OF THE SUN

Odessa Astronomical Publications, 2013
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 ...
