Abstract: Wind measurements made by aircraft of Project Jet Stream during forty-eight flights are compared with geostrophic and gradient winds (computed on upper-air charts) in order to determine geostrophic and gradient departures. ...

Abstract: Aircraft observations over the central United States are used to construct empirical models of jet streams that agree well with models based on data from other regions of the mid-latitudes. Individual jet streams conform ...

Abstract: Due to a lack of observational data, little information exists in the literature concerning quantitative relationships between turbulent gust intensity in the free atmosphere and commonly measured meteorological quantities. ...

Abstract: Typical jet stream characteristics are illustrated by discussions of an average, a strong and a weak jet stream. The basic data were obtained by aircraft of Project Jet Stream in flights carried out mainly over the ...
