On the basis of a wide range of documents the article analyzes main stages and factors of the Czech Republic integration with the North Atlantic Treaty Organizations. The author emphasizes that transition into a full NATO member in March 1999 was the result of a long, complicated and controversial process of «European Come Back», which started in the beginning of 1990’s and allowed the state’s government to solve a number of problems in the military-political and military-technical spheres. The article draws special attention to the results and consequences of the Czechia NATO membership, its participation in the structures and activities of the Alliance. Numerous facts provided in the paper allow to evaluate the state’s gains from the integration processes and to emphasize key tendencies, main challenges and new opportunities for the country. The study proves that Euro-Atlantic integration has contributed to the institutional and legal reconstruction of the entire system of foreign relations of the Czech Republic, has become an important stimulus to the transition to a democratic model of political system, stability and national security. The article examines the defense strategy of the Czech Republic, reveals its goals and objectives in the field of European security and defense at the present stage. It is noted that NATO Allies supported the proposal to update the 2010 Strategic Concept. Since its adoption the Alliance has faced a new security environment and Russia has turned from a potential strategic partner into an aggressor state. The Czech experience has revealed the advantages and vulnerabilities of the Euro-Atlantic vector. Last but not lease the article studies the causes of polyvariety of the Euro-Atlantic realities and prospects for Alliance enlargement. Based on the results of public opinion polls conducted by the Czech research organizations, the article examines the attitude of Czech political parties and citizens towards their country’s membership in NATO, the role of the North Atlantic Alliance in ensuring the security of the Czech Republic and international relations in general.

AbstractAtmospheric stochastic forcing associated with the North Atlantic Oscillation (NAO) and intrinsic ocean modes associated with the large-scale baroclinic instability of the North Atlantic Current (NAC) are recognized as two strong paradigms for the existence of the Atlantic multidecadal oscillation (AMO). The degree to which each of these factors contribute to the low-frequency variability of the North Atlantic is the central question in this paper. This issue is addressed here using an ocean general circulation model run under a wide range of background conditions extending from a supercritical regime where the oceanic variability spontaneously develops in the absence of any atmospheric noise forcing to a damped regime where the variability requires some noise to appear. The answer to the question is captured by a single dimensionless number Γ measuring the ratio between the oceanic and atmospheric contributions, as inferred from the buoyancy variance budget of the western subpolar region. Using this diagnostic, about two-thirds of the sea surface temperature (SST) variance in the damped regime is shown to originate from atmospheric stochastic forcing whereas heat content is dominated by internal ocean dynamics. Stochastic wind stress forcing is shown to substantially increase the role played by damped ocean modes in the variability. The thermal structure of the variability is shown to differ fundamentally between the supercritical and damped regimes, with abrupt modifications around the transition between the two regimes. Ocean circulation changes are further shown to be unimportant for setting the pattern of SST variability in the damped regime but are fundamental for a preferred time scale to emerge.

Studies of dredged and drilled samples from the North Atlantic ocean have revealed that basalts with a wide range of major and trace element compositions have been generated at the Mid-Atlantic Ridge (M.A.R.). Many of the basalts erupted between latitudes 30° and 70° N do not have the geochemical characteristics of normal mid-ocean ridge basalts (m.o.r.b.) depleted in the more-hygromagmatophile (hyg.) elements. Drilling along mantle flow lines transverse to the ridge has shown that different segments of the M.A.R. have produced basalts with a distinct compositional range for tens of millions of years. As more data have become available, the nature and scale of this variation have been established and tighter constraints can now be placed on the petrogenetic processes involved. The rare earth elements are used to test quantitatively the effects of open and closed system fractional crystallization, equilibrium partial melting (including continuous melting), zone refining and mantle mixing processes on basalt chemistry. When evaluated in terms of the more-hyg. elements, the results show that major heterogeneities must exist in the mantle sources feeding the M.A.R. Ratios of many of the more-hyg. elements remain consistent in space and time in basalts erupted at a particular ridge segment, but vary widely between different ridge segments. These ratios are not significantly modified by the processes of basalt generation. The hyg. element relations provide a major constraint on the nature of heterogeneity in the Earth’s mantle and the processes producing it. The mantle sources of anomalous ridge segments can be best explained in terms of variable veining of a hyg. element depleted host by a hyg. element enriched liquid or fluid generated by very small degrees of partial melting. Such incipient melting, as well as subduction zone processes, may be viable mechanisms for changing hyg. element ratios in the mantle source regions on the scale observed. These processes can be integrated into a model for mantle evolution which involves (1) upward migration of incipient melts to provide a hyg. element enriched source for alkali basalts and a hyg. element depleted source for normal m.o.r.b., and (2) extraction of continental crust and recycling of the depleted residue into the mantle at subduction zones. Also, some recycling of continental material into the mantle may be required to explain Pb isotope patterns.

Abstract. The North Atlantic Marine Boundary Layer Experiment (NAMBLEX), involving over 50 scientists from 12 institutions, took place at Mace Head, Ireland (53.32° N, 9.90° W), between 23 July and 4 September 2002. A wide range of state-of-the-art instrumentation enabled detailed measurements of the boundary layer structure and atmospheric composition in the gas and aerosol phase to be made, providing one of the most comprehensive in situ studies of the marine boundary layer to date. This overview paper describes the aims of the NAMBLEX project in the context of previous field campaigns in the Marine Boundary Layer (MBL), the overall layout of the site, a summary of the instrumentation deployed, the temporal coverage of the measurement data, and the numerical models used to interpret the field data. Measurements of some trace species were made for the first time during the campaign, which was characterised by predominantly clean air of marine origin, but more polluted air with higher levels of NOx originating from continental regions was also experienced. This paper provides a summary of the meteorological measurements and Planetary Boundary Layer (PBL) structure measurements, presents time series of some of the longer-lived trace species (O3, CO, H2, DMS, CH4, NMHC, NOx, NOy, PAN) and summarises measurements of other species that are described in more detail in other papers within this special issue, namely oxygenated VOCs, HCHO, peroxides, organo-halogenated species, a range of shorter lived halogen species (I2, OIO, IO, BrO), NO3 radicals, photolysis frequencies, the free radicals OH, HO2 and (HO2+Σ RO2), as well as a summary of the aerosol measurements. NAMBLEX was supported by measurements made in the vicinity of Mace Head using the NERC Dornier-228 aircraft. Using ECMWF wind-fields, calculations were made of the air-mass trajectories arriving at Mace Head during NAMBLEX, and were analysed together with both meteorological and trace-gas measurements. In this paper a chemical climatology for the duration of the campaign is presented to interpret the distribution of air-mass origins and emission sources, and to provide a convenient framework of air-mass classification that is used by other papers in this issue for the interpretation of observed variability in levels of trace gases and aerosols.

Abstract Numerous representatives of theories of international relations, security theories or alliance theories have examined the new role of the North Atlantic Alliance or the North Atlantic Treaty Organization (NATO) in the post-bipolar world. Parallel with the theoretical examination of goals and tasks, NATO has transformed itself in practice, following the realities of the contemporary global era. In trying to achieve and keep the primacy of the strongest military- political organization, the Alliance has - especially in the Strategic Concept adopted in Lisbon in 2010-set the normative and institutional foundations of its global engagement, fulfilling the military (hard) and a wide array of non-military (soft) security challenges. This strategy has given rise to "Euro-Atlanticism", as a subsystem of international relations based on strong American-European relations, to fit with the process of regionalization of global politics. However, the 2013-2014 crisis in Ukraine has turned the focus of interest and activities of NATO once again primarily to Europe and it has stressed the importance and necessity of strengthening Euro-Atlantic security and defence ties. The most powerful member of the Alliance, the United States, is again strongly engaged in Europe and Russia, as a kind of successor to the Soviet Union, is once more detected as a major threat to European security. There have been many aspects of theories of international relations that have tried to explain the dynamic of the post-Cold War international community. However, the approach based on neo-realistic assumptions of the role of a security community, collective defence and the use of military force has proved to be dominant. NATO will continue to work on its political dimension as an alliance of the democratic world and the September 2014 Wales Summit will certainly mark the return of NATO to its roots, strengthening its security and military dimensions in the collective defence of Europe from Russia.

The North Atlantic Treaty Organization (NATO) and the European Union's (EU) European Security and Defense Policy (ESDP) both occupy the policy space of crisis management. This overlap has two effects. First, overlap has generated “chessboard politics” shaping member state strategies. Second, institutional overlap has generated a number of feedback effects. The prior existence of NATO shaped the conceptualization and organization of ESDP at its creation, and the existence of two alternative security institutions continues to influence the ways that the institutions evolve—how each institution defines security interests and how member states adjust the mandate of each institution to address changes in the security environment. Because both institutions are intergovernmentally organized and consensus-based, the actions and decisions of both institutions reflect the agreements of members. Chessboard politics and feedback effects are consequently interrelated—states strategize to affect outcomes in one venue or another, and decisions in one institution can affect decisions and behaviors in the other institution.
