Abstract: The three-dimensional structure and propagation characteristics of tropical synoptic scale transients during the northern summer we studied with twice daily ECMWF global gridded analyses for the 1980?1987 period. Regions ...

Abstract: Periods of enhanced synoptic activity in the tropical western Pacific, Bay of Bengal-northeastern India, and African-Atlantic regions are identified by extended empirical orthogonal function analysis. Composite mete-orological ...

Abstract: Spatial patterns and seasonality of interannual and interdecadal variability in the 500-hPa geopotential height, sea level pressure, and 1000-500-hPa thickness field are examined based on NMC analyses over the Northern ...

Abstract: On 7 June 1998, a mesoscale convective system (MCS), associated with a mesoscale cyclone, was initiated on the south side of a mei-yu front near Hong Kong and developed over the Taiwan Strait. In this study, numerical ...

Abstract: Typhoon Winnie (1997) was the fourth supertyphoon in the western North Pacific in 1997. In its mature stage, an outer eyewall, consisting of deep convection with a diameter of 370 km, was observed by satellite and radar. ...
