Retrospective predictions of seasonal hurricane activity in the Atlantic and east Pacific are generated using an atmospheric model with 50-km horizontal resolution by simply persisting sea surface temperature (SST) anomalies from June through the hurricane season. Using an ensemble of 5 realizations for each year between 1982 and 2008, the correlations of the model mean predictions with observa...

Using station rainfall data and NCEP/NCAR reanalysis from 1978-2007, we characterize the spatial variations of the heavy rainfall (Meiyu) during June-July over the Jiang-Huai basin (JHB, ~28°–34° N and 110°–122° E) in East China and their associated atmospheric circulations. An empirical orthogonal function (EOF) analysis of the Meiyu rainfall revealed 2 other significant modes besides the domi...

The 2008 Wells earthquake occurred on a northeast-striking, southeast-dipping fault that is clearly delineated by the aftershock swarm to a depth of 10-12 km below sea level. However, Cenozoic rocks and structures around Wells primarily record east-west extension along northto north-northeast-striking, west-dipping normal faults that formed during the middle Miocene. These faults are responsibl...

[1] Contemporary deformation of the Yellowstone hot spot and surrounding western United States is analyzed using tectonic microplate modeling, employing constraints from GPS observations corrected for postseismic deformation of M7+ earthquakes, fault slip rates, and earthquake focal mechanisms. We focus primarily on the kinematics of the Yellowstone hot spot and the eastern Snake River Plain vo...

The δO of seawater (δOw), an indirect indicator of sea surface salinity (SSS), in the northern East China Sea (ECS) is reconstructed for the Holocene using paired analyses of Mg /Ca ratio and δO of planktic foraminiferal tests. According to modern observation, interannual variations in SSS during summer in the northern ECS are mainly controlled by the Changjiang (Yangtze River) discharge, which...

Fossil plants are abundant in dolomite of the Clear Fork Group (Leonardian; late Early Permian) in the North Robertson Unit of the Robertson Clear Fork oil field of Gaines County, West Texas. The unit is a portion of the larger Robertson field. Thirty-seven separate collections were made from drill cores taken in three wells, spanning an interval 300 m thick from a depth below the surface of > ...

Magnetostratigraphy of sedimentary rock deposited in the Chaka basin (north-easternTibetan Plateau) indicates a lateMiocene onset of basin formation and subsequent development of the adjacent Qinghai Nan Shan. Sedimentation in the basin initiated at 11Ma. In the lower part of the basin ¢ll, a coarsening-upward sequence starting at 9Ma, as well as rapid sedimentation rates, and northward paleocu...
