Abstract. The North Atlantic Oscillation (NAO) affects atmospheric variability from eastern North America to Europe. Although the link between the NAO and winter precipitations in the eastern North America have been the focus of previous work, only few studies have hitherto provided clear physical explanations on these relationships. In this study we revisit and extend the analysis of the effect of the NAO on winter precipitations over a large domain covering southeast Canada and the northeastern United States. Furthermore, here we use the recent ERA5 reanalysis dataset (1979–2018), which currently has the highest available horizontal resolution for a global reanalysis (0.25°), to track extratropical cyclones to delve into the physical processes behind the relationship between NAO and precipitation, snowfall, snowfall-to-precipitation ratio (S/P), and snow cover depth anomalies in the region. In particular, our results show that positive NAO phases are associated with less snowfall over a wide region covering Nova Scotia, New England and the Mid-Atlantic of the United States relative to negative NAO phases. Henceforth, a significant negative correlation is also seen between S/P and the NAO over this region. This is due to a decrease (increase) in cyclogenesis of coastal storms near the United States east coast during positive (negative) NAO phases, as well as a northward (southward) displacement of the mean storm track over North America.

The anonymous author of a paper published in the November 1857 issue of The Nautical Magazine, introduced a novel philosophy in relation to the location of lighthouses. At the same time he discussed the proposition for a coastal traffic separation scheme for the English Channel — notorious then, as it still is, for its high incidence of collisions and groundings. The proposal was made just two years after Walter R. Jones of New York made his suggestion to Lieut. M. F. Maury of the United States Navy for an ocean traffic separation scheme which materialized in the form of Maury's ‘steam lanes’ for the North Atlantic.

Abstract. The North Atlantic Oscillation (NAO) affects atmospheric variability from eastern North America to Europe. Although the link between the NAO and winter precipitations in eastern North America has been the focus of previous work, only few studies have considered extreme precipitation and hitherto provided clear physical explanations on these relationships. In this study we revisit and extend the analysis of the effect of the NAO on mean and heavy winter precipitations over a large domain covering southeast Canada and the northeastern United States. Furthermore, we use the recent ERA5 reanalysis dataset (1979–2018), which currently has the highest available horizontal resolution for a global reanalysis (0.25∘), to track extratropical cyclones to delve into the physical processes behind the relationship between NAO and precipitation, snowfall, snowfall-to-precipitation ratio (S∕P), and snow cover depth anomalies in the region. In particular, our results show that positive NAO phases are associated with less snowfall over a wide region covering Nova Scotia, New England and the Mid-Atlantic of the United States relative to negative NAO phases. Over the same area, the analysis of heavy snowfall revealed that there are up to twice as many heavy snowfall events during negative phases compared to positive phases. Therefore, a significant negative correlation is also seen between S∕P and the NAO over this region. This is due to a decrease (increase) in cyclogenesis of coastal storms near the United States east coast during positive (negative) NAO phases, as well as a northward (southward) displacement of the mean storm track over North America.

Six recurrent thermal regimes are identified over continental North America from June to September through a k-means clustering applied to daily maximum temperature simulated by ECHAM5 forced by historical SSTs for 1930–2013 and validated using NCEP–DOE AMIP-II reanalysis over the 1980–2009 period. Four regimes are related to a synoptic wave pattern propagating eastward in the midlatitudes with embedded ridging anomalies that translate into maximum warming transiting along. Two other regimes, associated with broad continental warming and above average temperatures in the northeastern United States, respectively, are characterized by ridging anomalies over North America, Europe, and Asia that suggest correlated heat wave occurrences in these regions. Their frequencies are mainly related to both La Niña and warm conditions in the North Atlantic. Removing all variability beyond the seasonal cycle in the North Atlantic in ECHAM5 leads to a significant drop in the occurrences of the regime associated with warming in the northeastern United States. Superimposing positive (negative) anomalies mimicking the Atlantic multidecadal variability (AMV) in the North Atlantic translates into more (less) warming over the United States across all regimes, and does alter regime frequencies but less significantly. Regime frequency changes are thus primarily controlled by Atlantic SST variability on all time scales beyond the seasonal cycle, rather than mean SST changes, whereas the intensity of temperature anomalies is impacted by AMV SST forcing, because of upper-tropospheric warming and enhanced stability suppressing rising motion during the positive phase of the AMV.

With the development of certain administrative frictions (concerning coal quotas, occupation costs, and the scrap metal treaty) between the western occupying powers and the German Federal Republic, early indications were that if the talk of “contractual agreements” did materialize it would reserve, for the occupying powers, wide controls over important areas of west Germany's internal and external affairs. In Washington, however, a general modification of approach was noted during the September discussions between the United States Secretary of State (Acheson), the United Kingdom Foreign Secretary (Morrison), and the French Foreign Minister (Schuman), preparatory to the Ottawa meetings of the North Atlantic Council.

The debate over strategy, forces, and nuclear control, which now divides the North Atlantic Treaty Organization (NATO), is framed largely in military terms: what is the best way to protect the NATO area and its members from aggression? The military aspects are complex in themselves, but the import of these issues extends far beyond defense. Their handling will greatly affect prospects for a partnership between the United States and a strong, united Europe

At the end of the 1940s, the United States and several West European states allied to defend themselves against invasion by the Soviet Union. Balance-ofpower theory predicts the recurrent formation of such balances among states. But it says little about the precise nature of the balance, the principles on which it will be constructed, or its institutional manifestations. The North Atlantic Treaty Organization (NATO) has been a peculiar mix. As a formal institution, NATO has through most of its history been distinctly nonmultilateral, with the United States commanding most decision-making power and responsibility. At the same time, NATO provided security to its member states in a way that strongly reflected multilateral principles. Within NATO, security was indivisible. It was based on a general organizing principle, the principle that the external boundaries of alliance territory were completely inviolable and that an attack on any border was an attack on all. Diffuse reciprocity was the norm. In the terms set out by John Ruggie, NATO has generally scored low as a multilateral organization but high as an institution of multilateralism.

This essay analyses the North Atlantic Cotton Trade through records of cotton arrivals at Liverpool, using two sets of data from 1830-1832 and 1853-1855. Using Customs Bills of Entry, Williams presents data of cotton receipts from the United States to Liverpool; quantities of bales exported; numbers of vessels; origin ports of vessels; distinguishes between regular and occasional cotton traders; arrivals at Liverpool by nationality; and vessel tonnage. He determines that the majority of vessels participated in the cotton trade seasonally, and suggests that the cotton trade was not self-contained, but part of a complex interrelationship within the North Atlantic trade system, encompassing commodity dealings, shipping employment levels, and the seasonal characteristics of cargo. The conclusion requests further scholarly research into the pattern of ship movements in the Atlantic. Two appendices provide more data, concerning arrival dates of regular traders in Liverpool, and the month of departure of cotton vessels from Southern states.

Abstract This essay develops a response to the historical situation of the North Atlantic world in general and the United States in particular through theological reflection. It offers an overview of some decolonial perspectives with which theologians can engage, and argues for a general perspective for a decolonial theology as a possible response to modern/colonial structures and relations of power, particularly in the United States. Decolonial theory holds together a set of critical perspectives that seek the end of the modern/colonial world-system and not merely a democratization of its benefits. A decolonial theology, it is argued, critiques how the confinement of knowledge to European traditions has closed possibilities for understanding historical encounters with divinity, and thus possibilities of critical reflection. A decolonial theology reflects critically on a historical situation in light of faith in a divine reality, the understanding of which is liberated from the monopoly of modern/colonial ways of knowing, in order to catalyze social transformation.
