Abstract: Mountain ranges and high plateaus influence atmospheric circulation patterns on all scales, ranging from ultralong planetary waves to small turbulent eddies. Some of these effects are brought about simply by orographic ...

Abstract: During September 1961 a series of balloon ascents made from Flin Flon, Canada, carrying scintillation counters sensitive to gamma radiation, revealed the existence of shallow stable atmospheric layers carrying radioactive ...

Abstract: A review is given of mathematical expressions for total and mean specific kinetic energies in the longitudinal, time, and mixed longitudinal-time domains. These coordinate domains differ from those defined earlier by Oort. ...

Abstract: It is shown that long-term trends in the meridional components of the trade wind circulations in both hemisphere over the Pacific are highly correlated with the precipitation falling in the intertropical convergence zone ...

Abstract: Precipitation surges in the equatorial Pacific ?dry zone? (as delineated in a study by Doberitz) reveal statistically significant teleconnections with midlatitude tropospheric flow patterns during all seasons. These ...

Abstract: Following the perturbation theory, the aircraft measurements of ?Project Jet Stream? Flight No. 29 (4 April 1957) have been analyzed, applying a double-smoothing technique, thus treating the basic fields of flow and ...

Abstract: The three-dimensional wind field in the vicinity of the jet stream is defined with the aid of four parameters: mean wind speed and direction, thickness, and mean altitude of the Layer of Maximum Wind (LMW). Routine methods ...

Abstract: Evidence is derived from observational data that the trade wind circulations in both hemispheres over the Pacific are related to the sea surface temperature (SST) anomalies in the North Pacific. The equatorward component ...

Abstract: Cloud-photogrammetric studies conducted from the ground reveal the existence of wave perturbations near tropopause level, of a wavelength the same order of magnitude as is experienced in clear-air turbulence. A case study ...
