Different Holocene sea-ice drift patterns in the Arctic Ocean have been hypothesized by Dyke et al. from radiometric analyses of driftwood collected in the Canadian Arctic Archipelago. A dynamic-thermodynamic sea-ice model is used to simulate the modes of Arctic Ocean ice circulation for different atmospheric forcings, and hence determine the atmospheric circulations which may have accounted fo...

Hypotheses and inferences concerning the nature of abrupt climate change, exemplified by the Dansgaard–Oeschger (D–O) events, are reviewed. There is little concrete evidence that these events are more than a regional Greenland phenomenon. The partial coherence of ice core yO and CH4 is a possible exception. Claims, however, of D–O presence in most remote locations cannot be distinguished from t...

Transmission tower is a very important component of power system, and heavy iced transmission line has became one of the important factors against its safety and stability in China's power system these years but the transmission line designed from traditional standard can't endure the more worse environment. In this paper, for positioning the weak points of the transmission line under heavy ici...

The time of protostellar wind breakout may be determined by the evolution of the infalling flow, rather than any sudden change in the central engine. I examine the transition from pure infall to outflow, in the context of the inside-out collapse of a rotating molecular cloud core. I have followed numerically the motion of the shocked shell created by the impact of a stellar wind and infalling g...

Upwellings are observed on the northern shelf of Taiwan during northeasterly winds. Analytical and realistic numerical models are used to explain how vertical motions are created by divergence and convergence produced by wind acting on the vorticity field of two strong jets: the Kuroshio and the Taiwan Warm Current. The seaward increase in cyclonic vorticity near the Kuroshio’s western edge fav...

Abstract Coastal offshore currents transport terrestrial materials from coastal areas to continental shelf in the upper layer; these are regarded as unimportant winter when wind‐driven onshore dominant. In this paper, both long‐term observations and high‐resolution simulations East China Sea reveal unique wintertime layer that widespread 30–70‐m isobath area even overcome at 50–70‐m isobaths. T...

Spaceborne SAR images acquired over the ocean in conjunction with weather radar images are well suited to study atmospheric fronts in coastal areas. In this paper we confine ourselves to study quasi-stationary atmospheric fronts off the east coast of Taiwan which are located typically 3070 km offshore. These quasistationary atmospheric fronts were first detected on ERS SAR images [5]. In [5] we...

A number of O stars are suspected to have (weak) magnetic fields because of the observed cyclical variability in their UV wind-lines. However, direct detections of these magnetic fields with optical spectropolarimetry have proven to be very difficult. We have searched for non-thermal radio emission, which would be a strong indication for the presence of a magnetic field. Of our 5 selected candi...
