Abstract: Evidence is presented that the circumpolar current of temperature latitudes often is not symmetric about the earth's axis of rotation. This asymmetry, which varies with time, is frequently so large that the ?zonal index? ...

Abstract: The structure of hurricane Cleo (1958) is presented, based on observations of wind, temperature, pressure, humidity, clouds, and precipitation obtained from three research reconnaissance aircraft of the National Hurricane ...

Abstract: A 3-hr flight of a constant-volume balloon which is entrained into a cumulus congestus cloud and lifted to an altitude of nearly 3 km provides an opportunity to determine the trajectory and vertical velocity of the balloon ...

Abstract: Changes of the general circulation, especially the strength of the upper westerlies, over 28 months are investigated quantitatively.The role of the high troposphere, represented by the 300-mb level, is stressed and it is ...

Abstract: This paper demonstrates that improved forecasts of the annual number of hurricanes in the Atlantic tropical basin are possible by separating tropical-only hurricanes from hurricanes influenced by extratropical factors. It ...

Abstract: A temporary mesoscale network of pilot balloon stations on a tropical island (Barbados, West Indies) revealed the existence of a low-level jet at 700 m above mean sea level, with a maximum wind near 40 m/s and a duration ...
