Abstract: A mathematical filter for eliminating persistence in meteorological data is proposed and discussed. This filter takes the form Zt=Xt??1Xt?l. Relationships between statistical parameters of the filtered and the original ...

Abstract: During the winters of 1961?62 and 1963?64, measurements of light scattering by falling snow provided a continuous record of snowfall rates on the campus of McGill University in Montreal. This permitted an analysis of the ...

Abstract: The results of a spectral analysis of the horizontal fluctuations in temperature and liquid water content measured by instrumented aircraft at four altitudes daily during four days in the life-cycle of a storm moving ...

Abstract: A major impediment to the development of computer algorithms for the automatic classification of ice particle types found in the atmosphere as measured by a Particle Measuring System two-dimensional probe is the difficulty ...

Abstract: Classification algorithms have been developed to distinguish six categories of cloud ice particles. These algorithms have been incorporated in schema which, when applied to shadowgraph images produced by the Precision ...
