Abstract: Forecast probabilities of rain were calculated up to 12 hours in advance using a Markov chain model applied to three-hourly observations from five major Australian cities. The four weather states chosen in this first study ...

Abstract: Routine estimates of certain atmospheric energetics parameters [AZ, KZ, AE, KE, C(AZ,AE), C(KE,KZ)] have been computed for the National Meteorological Center's routine 0000 and 1200 GMT analyses and for the 00, 12, 24, 36, ...

Abstract: Monthly mean values of the geostrophic angular momentum transport at 500 mb. have been computed as a function of latitude and zonal wave number (1 through 10) for a 10-yr. period. The total transport is found to be in good ...

Abstract: Evidence is presented for an approximate year-to-year variation of the zonal available potential (AZ), eddy available potential (AE), zonal kinetic (KZ) and eddy kinetic energy (KE) in the extra-tropical troposphere between ...

Abstract: Comparison is made between the horizontal wave energy flux at 32.5N for the atmospheric layers 700?500 mb and 300?200 mb, as computed by the approximation of Eliassen and Palm, and the observations of Oort and Rasmusson. ...

Abstract: While several mechanisms have been suggested to account for the association of the Arctic and Antarctic Oscillations (AO/AAO) with atmospheric parameters, this paper focuses on the relationship with the atmospheric outgoing ...

Abstract: Significant advances have been made recently both in observational studies and in dynamical numerical simulations of stratosphere warmings. Observed characteristics of warmings are reviewed, with discussion of the trajectory ...

Abstract: By means of spectrum analysis of 11 years of lower stratospheric daily winds and temperatures at Balboa, Ascension and Canton-Singapore, evidence is presented supporting the existence of two principal wave modes with periods ...

Abstract: Results of comparisons of wind and temperature data obtained by closely spaced launchings of Japanese MT-135 and American ARCAS meteorological rocket systems are presented. In general, smoothed temperature profiles show a ...
