Atmospheric circulation modulates the spatial variability of temperature in the Atlantic-Arctic region
2019
International audience; The Arctic region has experienced significant warming during the past two decades with major implications on the cryosphere. The causes of Arctic amplification are still an open question within the scientific community, attracting recent interest. The goal of this study is to quantify the contribution of atmospheric circulation on temperature variability in the Atlantic–Arctic region at decadal to intra‐annual timescales from 1951 to 2014. Daily 20th Century reanalyses geopotential height anomalies at 500 hPa were clustered into different weather regimes to assess their contribution to observed temperature variability. The results show that in winter, 25% of the warm…
The role of the agreement as a tool for management of property relations in cases of cross border marriages and civil unions/partnerships registered …
2021
The essay examines the role of the agreement as a tool for managing property relationships in crossborder marriages and registered partnerships, in light of EU Regulations 1103 and 1104 of 2016, on the property regimes of international married or registered couples. The main prerogative of such acts is the recognition of the parties? freedom to choose the court and the applicable law. The law governing the matrimonial property regimes, or the property consequences of registered partnerships, has universal scope. This agreement in the form envisaged, which is backed by the need for legal certainty and predictability of the applicable rules, means that the spouses, in family problems which ha…
Baltijas jūras ledus apstākļu ietekme uz gaisa temperatūras raksturu un diennakts svārstību amplitūdu Ventspils apkārtnē
2020
Bakalaura darba tēma ir “Baltijas jūras ledus apstākļu ietekme uz gaisa temperatūras raksturu un diennakts svārstību amplitūdu Ventspils apkārtnē”. Darba gaitā tika ievākti un analizēti dati par maksimālajām un minimālajām diennakts gaisa temperatūrām un to amplitūdām no Ventspils, Daugavpils un Alūksnes novērojumu stacijām gada aukstajā periodā (XI-IV). Tika apskatītas sakarības starp Baltijas jūras ledus stāvokli un gaisa temperatūrām Ventspils novērojumu stacijā. Ventspils ir piekrastes novērojumu stacija, bet Daugavpils un Alūksne - kontinentālas novērojumu stacijas. Ventspils diennakts maksimālās, minimālās gaisa temperatūras un to amplitūdas tika salīdzinātas ar Daugavpils un Alūksnes…
Dynamics of a harmonic oscillator coupled with a Glauber amplifier
2020
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system may be exactly subdivided into invariant finite dimensional subspaces. Resorting to the Jordan-Schwinger map, the dynamical problem within each invariant subspace may be traced back to an effective SU(2) Hamiltonian model expressed in terms of spin variables only. This circumstance allows to analytically solve the dynamical problem and thus to study the exact dynamics of the oscillator-amplifier system under specific time-dependent scenarios. Peculiar physical effects are brought to light by comparing the dynamics…
