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...

Clouds are the largest modulators of the solar radiative flux reaching the Earth’s surface. The amount and type of cloud cover prevailing at a given time and location largely determines the amount and type of solar radiation received at the Earth’s surface. This cloud radiative forcing is different for the different solar spectral bands. In this work, we analysed the influence of cloud radiativ...

We report on optical and infrared observations of the anomalous X-ray pulsar (AXP) 1E 1048.1−5937, made during its ongoing X-ray flare which started in 2007 March. We detected the source in the optical I and near-infraredKs bands in two ground-based observations and obtained deep flux upper limits from four observations, including one with the Spitzer Space Telescope at 4.5 and 8.0 μm. The dete...

We present models for the thermal and mechanical equilibria of slender magnetic loops on rapidly-rotating stars. These loops are embedded within an arcade located on the stellar equator. The loop properties are governed principally by the specified base pressure and conductive flux. While rapid rotation is important in determining the pressure structurewithin the loop, its main effect on the lo...

We observed 64 newly identified galactic bulge planetary nebulae in the radio continuum at 3 and 6 cm with the Australia Telescope Compact Array. We present their radio images, positions, flux densities, and angular sizes. The survey appears to have detected a larger ratio of more extended planetary nebulae with low surface brightness than in previous surveys. We calculated their distances acco...

The two-dimensional multifluid code TECXY has been used to model the biasing (with respect to the first wall) of the toroidal belt limiter ALT-II on the tokamak TEXTOR-94 and of the new toroidal pump limiter being installed on Tore Supra tokamak in the framework of the CIEL project. It is well known that the edge flow pattern can be influenced by the poloidal electric drifts from imposing radia...

Measurements of fast phenomena in the vicinity of a limiter inserted into a linear plasma column are shown in this work. The results were conducted at the plasma generator PSI-2 (Humboldt Universitaet zu Berlin, Germany) which provides a stationary plasma produced in a DC arc discharge. The plasma near a tungsten limiter was imaged on a photomultiplier tube equipped with 16 anodes. The photomul...

A theoretical investigation is performed for studying the flow of heat transfer characteristics of Sakiadis and Blasius flow of magnetohydrodynamic Maxwell fluid with thermal radiation. We also incorporated the Cattaneo-Chirstov heat flux model to control the heat transfer phenomena. Numerical solutions are carried out by using Shooting technique. The effects of various governing parameters on ...

Anthropogenic heat flux (QF) may be significant in cities, especially under low solar irradiance and at night. It is of interest to many practitioners including meteorologists, city planners and climatologists. QF estimates at fine temporal and spatial resolution can be derived from models that use varying amounts of empirical data. This study compares simple and detailed models in a European m...

This paper develops appropriate boundary conditions for the two-sided fractional diffusion equation, where the usual second derivative in space is replaced by a weighted average of positive and negative fractional derivatives. Mass preserving, reflecting boundary conditions for two-sided fractional diffusion involve a balance of left and right fractional derivatives at the boundary. Stable, con...
