Abstract: Time-lapse photographs taken of a visual tracer laid in horizontal lines at several levels, one above the other, show convective motion of the air in a vertical plane. Through minor improvements in technique a three-dimensional ...

Abstract: A mathematical framework is described which allows the logical joining of the processes of condensation, collection and advection, and also freezing and electrical effects in a cloud model.

Abstract: Common motor oil is injected into the exhaust manifold of an aircraft where it is vaporized, and then mixes into the cold outside air to condense into a dense oil fog. This air marking technique has been used in atmospheric ...

Abstract: Accretion is shown to have a narrowing effect on the drop size distribution while the newly defined processes ?large hydrometeor self-collection, ? is shown to he responsible for the rapid growth of large hydrometeors and ...

Abstract: A new, highly accurate, yet fast method for the numerical solution of the stochastic collection equation is described. Basic size distribution parameters are defined that lay a basis for a parameterized description of ...

Abstract: The initial spreading of a cloud droplet distribution, its time of formation and placement of the second maximum, and the value of the minimum between the two maxima are systematically related to the mean mass and standard ...

Abstract: A new parameterization of cloud particle growth combines the effects of accretion and self-collection, and frees the large-hydrometeor water mass and spectral moments to grow independently. The large-hydrometeor water mass ...

Abstract: The experimental data of Gunn and Kinzer, Beard and Pruppacher, and Davies are used to curve-fit a polynomial for Re in terms of CdRe2. The resulting equations predict very accurately all known experimental data for drop ...
