Episodic Trade Wind Regimes over the Western Pacific Warm Pool
The western Pacific warm pool experiences the greatest rainfall of any oceanic region on earth. While the SST is everywhere high over the warm pool, there is great spatial and temporal variability in rainfall. Sounding data from the recent TOGA COARE are used to document this variability. In particular, the vertical distributions of heating and moistening at different phases of the 30–60 day or...
متن کاملWarm Absorbers in Agn: a Multi-temperature Wind
Although soft X-ray absorption features in AGN were discovered almost ten years ago, the nature and location of the gas creating them has remained controversial. Guided by the results of recent highresolution X-ray spectroscopy, we argue that these features are created in a multi-temperature wind whose source of matter is photoionized evaporation from the inner edge of the obscuring torus often...
متن کاملDetection of a warm molecular wind in DG Tauri
We detect near-infrared H2 emission in DG Tau using the Infrared Camera and Spectrograph (IRCS) on the 8.2-m SUBARU telescope. The spectra obtained along the jet axis show that the centroidal position of the 1–0 S(1) emission is offset by 0.2′′ from the star towards the jet, while those obtained perpendicular to the jet axis show a marginal extension, indicating that the emission line region ha...
متن کاملThe warm circumstellar envelope and wind of the G 9 IIb star HR 6902
ASTRONOMY AND ASTROPHYSICS The warm circumstellar envelope and wind of the G9 IIb star HR 6902 Abstract. IUE observations of the eclipsing binary system HR 6902 obtained at various epochs spread over four years indicate the presence of warm circumstellar material enveloping the G9 IIb primary. The spectra show Si iv and C iv absorption up to a distance of 3.3 giant radii (R g). Line ratio diagn...
متن کاملLarge wind shift on the great plains during the medieval warm period.
Spring-summer winds from the south move moist air from the Gulf of Mexico to the Great Plains. Rainfall in the growing season sustains prairie grasses that keep large dunes in the Nebraska Sand Hills immobile. Longitudinal dunes built during the Medieval Warm Period (800 to 1000 years before the present) record the last major period of sand mobility. These dunes are oriented NW-SE and are compo...
