The simulation of Arctic sea ice and surface winds changes significantly when CCSM3 resolution is increased from T42 ( 2.8 deg) to T85 ( 1.4 deg). At T42 resolution, Arctic sea ice is too thick off the Siberian coast and too thin along the Canadian coast. Both of these biases are reduced at T85 resolution. The most prominent surface wind difference is the erroneous North Polar summer anticyclon...

We extend previous 2-D models of line-driven winds from rotating hot stars by accounting for the dependence of ionization structure and occupation numbers on local physical properties (density, velocity field) and the non-local stellar radiation field. For this purpose, we formulate for the first time an approximate non-LTE description of 2-D winds. We propose the concept of a “mean irradiating...

sensitivity of upper thermocline properties to tropical cyclone winds and possible feedbacks on the Hadley circulation" (2010). [1] The sensitivity of upper thermocline properties, and global climate, to tropical cyclone (TC) winds is examined using global ocean and atmosphere general circulation models. We combine seven years of global, satellite‐based TC wind records with a standard surface w...

A new self-sustained model for long-term light curve variations of RX J0513.9−6951 is proposed based on an optically thick wind model of mass-accreting white dwarfs (WDs). When the mass accretion rate to a WD exceeds the critical rate of ∼ 1×10M⊙ yr , optically thick strong winds begin to blow from the WD so that a formation of common envelope is avoided. The WD can accrete and burn hydrogen-ri...

Moth migration has been assumed to involve hitching a ride in favorable winds. A new study has shown that silver Y moths migrate only on nights when winds would displace them southward, implying that they detect their direction of movement while airborne, likely by a magnetic sense.

Multiwavelength data on star-forming galaxies provide strong evidence for large-scale galactic winds in both nearby and distant objects. The results from recent ground-based and space-borne programs are reviewed. The impact of these winds on the host galaxies and the surrounding environment is discussed in the context of galaxy evolution.
