[1] The impacts of stratospheric ozone depletion on the extremes of daily precipitation in the austral summer are explored using two global climate models. Both models indicate that stratospheric ozone losses since the late 1970s may have increased the frequency and intensity of very heavy precipitation in austral summer over southern high and subtropical latitudes, and may have decreased the f...

It has long been known that the serum of certain leprosy patients gives positive reactions with tests for syphilis. These reactions have not been understood and have been interpreted as biologic ‘(false positives.” The reason for this interpretation undoubtedly lies in the widespread assumption that only in syphilis and in closely related diseases, such as yaws and bejel, are serum reactions wi...

Abstract Over most tropical land areas, the annual peak in precipitation occurs during summer, associated with local monsoon circulation. However, some coastal regions tropics bulk of autumn, after low-level summer westerlies have abated. Examples include Nordeste region Brazil, southeastern India and Sri Lanka, Tanzania. Unlike equatorial regions, they receive little rainfall spring. Such are ...

The variability of winter precipitation over the northeastern United States and the corresponding teleconnections with five dominant large-scale modes of climate variability (Atlantic Multidecadal Oscillation, AMO; North Atlantic Oscillation, NAO; Pacific-North American pattern, PNA; Pacific Decadal Oscillation, PDO; and El Niño–Southern Oscillation, ENSO) were systemically analyzed in this stu...
