We present ocean model sensitivity experiments aimed at separating the influence of the projected changes in the ‘‘thermal’’ (near-surface air temperature) and ‘‘wind’’ (near-surface winds) forcing on the patterns of sea level and ocean heat content. In the North Atlantic, the distribution of sea level change is more due to the ‘‘thermal’’ forcing, whereas it is more due to the ‘‘wind’’ forcing...

to doing this research daily interpolated temperature data from asfezari data base have been used. in order to recognition extreme cold days, the normalized temperature deviation index (ntdi) applied. then the index sorted according to extensive and severity and first 500 days selected for analysis. the geopotential height data extracted from www.esrl.noaa.gov data base. the thickness anomaly c...

ABsTRAcr Thc intermediate-wavelength geoid (A #)oo km) and sea-fbor topography fields in the central Pacific Ocean have been studied in terms of static and dynamic compensation models. Topographic fcatures on the sea-floor with As lo00 km haw been found to be wmpcnsatcd both regionally, by thc elastic strength of the lithosphere, and locally, by displacing mantle material to reach isostatic adj...

Crustal thickness is a critical parameter for understanding the processes of continental rifting and breakup and the evolution of petroleum systems within passive margins. However, direct measurements of crustal thickness are sparse and expensive, highlighting the need for methodologies using gravity anomaly data, jointly with other geophysical data, to estimate crustal thickness. We evaluated ...

Apatite fission-track analysis was applied to Triassic and Cretaceous sediments from the South-Iberian Continental Margin to unravel its thermal history. Apatite fission-track age populations from Triassic samples indicate partial annealing and point to a maximum temperature of around 100–110 °C during their post-depositional evolution. In certain apatites from Cretaceous samples, two different...

Proton magnetic resonance datal) in solid methane were analyzed by using the one parameter theory2) and the perturbation method. Assuming a single molecule as a unit of reorientation we obtained from the spin-lattice relaxation time the result shown in Fig. 1, where loglo r c is plotted against reciprocal tem perature. r c decreases with increasing temperature and rather sudden alterations of t...

The finite-temperature one-loop effective potential for a scalar field in the static de Sitter space-time is obtained. Within this framework, by using zeta-function regularization, one can get, in the conformally invariant case, the explicit expression for the stress tensor anomaly. Its value turns out to depend on the thermal state of the system. This conclusion is different from the one deriv...
