Abstract: Water drops of 2 mm diameter were supercooled on a glass slide, sprayed with AgI particles, and photographed at low magnification with a 16-mm movie camera at a speed of 64 frames per second to determine the nature of ...

Abstract: Droplet freezing by surface nucleation has been observed during the course of studies of ice nucleation in our laboratories. A constant rate of cooling apparatus and a specially constructed cold chamber were used for this ...

Abstract: Recent attempts to understand the development of intense precipitation has led several investigators to speculate about the role of drop impactions. Working with a large vertical wind tunnel, investigations were carried ...

Abstract: The freezing of freely suspended, supercooled water drops by contact nucleation has been studied. Water drops were balanced in an updraft of a large vertical wind tunnel and allowed to supercool to the ambient temperature. ...

Abstract: The design and operation of a large vertical wind tunnel (1.8 m diameter updraft) are described, together with the associated special photographic equipment and techniques required for studies of the interactions and ...
