Periodic Variation of Solar Flare Index for the Last Solar Cycle (Cycle 24)
Advances in Astronomy, 2021 In this study, we used the flare index (FI) data taken from Kandilli Observatory for the period of 2009–2020. The data sets are analyzed in three categories as Northern Hemisphere, Southern Hemisphere, and total FI data sets.

How the Great Plains Dust Bowl drought spread heat extremes around the Northern Hemisphere
Scientific Reports, 2022 Extraordinary heat extremes occurred in the 1930s in areas of the Northern Hemisphere far from the record setting heat over the US associated with the Great Plains Dust Bowl drought.

Simulating late Pliocene northern hemisphere climate with the LLN 2-D model [PDF]
, 1998 Deep-sea sediment records suggest Northern Hemisphere glaciation intensified at approximately 2.75 Ma. In this paper we simulate the fluctuations of the late Pliocene Northern Hemisphere ice-sheets volume using the LLN 2-D model, forced by the ...

Trends and emissions of six perfluorocarbons in the Northern Hemisphere and Southern Hemisphere [PDF]
Atmospheric Chemistry and Physics, 2020 Abstract. 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 order of thousands of years.

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.

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 ...

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.
