“…Analysis of the results focused on the Northern Hemisphere in winter. Compared with the L42 model, the L34 model produces a poorer simulation of the stratospheric Brewer–Dobson circulation (BDC) in the lower stratosphere, with weaker polar downwelling and accompanying cold-pole and westerly jet biases. …”

Predictability of an Atmospheric Blocking Event that Occurred on 15 December 2005 by Matsueda, M, Kyouda, M, Toth, Z, Tanaka, H, Tsuyuki, T

“…The JMA GSM multianalysis ensemble forecasts revealed that regional amplification of initial perturbations over the sensitive area could lead to further improvements in forecasts over the blocking region without degradation of forecasts over the Northern Hemisphere (NH), whereas the global amplification of initial perturbations could lead to improved forecasts over the blocking region and degraded forecasts over the NH. …”

Cross-equatorial channel flow with zero potential vorticity under the complete Coriolis force by Stewart, A, Dellar, P

“…The leading-order solution describes a current that switches from the western to the eastern side of the channel as it crosses from the southern to the northern hemisphere. Including the non-traditional component of the Coriolis force substantially increases the cross-equatorial transport as long as the flow is everywhere northwards, but substantially decreases the transport if part of the flow retroflects and returns to the southern hemisphere. …”

A well-established Early Middle Pleistocene marine sequence on south-east Zakynthos island, western Greece: magneto-biostratigraphic constraints and palaeoclimatic implications by Papanikolaou, MD, Triantaphyllou, M, Platzman, E, Gibbard, P, Mac Niocaill, C, Head, M

“…The sequence is divided into three formations by two main unconformities that apparently relate to sea-level lowstands associated with two major northern hemisphere glaciations, those of marine isotope stages (MIS) 22 and 12. …”

Temperature, carbon dioxide and methane may be linked through sea ice dynamics by Hambler, C, Henderson, PA

“…<p><strong>Background:</strong> The seasonal cycle of atmospheric carbon dioxide is usually ascribed to the seasonality of Northern Hemisphere vegetation, and the seasonal cycle of methane is usually ascribed to seasonal removal by the hydroxyl radical.…”

Timing of birth and risk of multiple sclerosis: population based study. by Willer, C, Dyment, D, Sadovnick, A, Rothwell, P, Murray, T, Ebers, G

“… OBJECTIVES: To determine if risk of multiple sclerosis (MS) is associated with month of birth in countries in the northern hemisphere and if factors related to month of birth interact with genetic risk. …”

Responses of Mesosphere and Lower Thermosphere Temperature to the Geomagnetic Storm on 7–8 September 2017 by Meng Sun, Zheng Li, Jingyuan Li, Jianyong Lu, Chunli Gu, Mengbin Zhu, Yufeng Tian

“…That is, the variations of temperature are more prominent in the northern hemisphere than in the southern hemisphere. Conversely, the TIMEGCM outputs agree with the observations in general but overestimate the temperature increases and underestimate the temperature decreases at high and middle latitudes. …”
