Secondary ice crystals are thrown off when supercooled cloud drops are captured and freeze on a moving target in a cloud at —5�C. The rate of production of these ice crystals is proportional to the rate of accretion of drops of the diameter ≥24 micrometers. 
Fragmentation of Freezing Drops in Shallow Maritime Frontal Clouds
Images of frozen drops with pieces missing were collected on two days of airborne sampling in shallow supercooled stratiform frontal clouds in the coastal waters of Washington State. In those limitedExpand
Production of secondary ice particles during the growth of graupel by riming
Experiments indicate that secondary ice crystals are produced when rime grows in a supercooled cloud containing drops ≥ 24μm in diameter. This occurs between temperatures of −3 and −8°C, theExpand
Mystery of ice multiplication in warm‐based precipitating shallow cumulus clouds
[1] High concentrations of ice crystals exceeding those of background ice nuclei have often been observed in warm-based precipitating shallow cumulus clouds. Laboratory experiments reveal that suchExpand
Temperature dependence of secondary ice crystal production during soft hail growth by riming
Simple experiments confirm that the production of secondary ice particles during the growth of rime depends upon the surface temperature of the riming particle rather than upon the cloud temperature.Expand
Microstructure of Atmospheric Clouds and Precipitation
Before discussing the microphysical mechanisms of cloud particle formation, we shall give a brief description of the main microstructural features of clouds. Here we shall be concerned primarily withExpand
Ice particle concentrations and precipitation development in small polar maritime cumuliform clouds
Increases in the concentrations of ice particles, as well as precipitation development, can proceed very rapidly in even quite small maritime cumuliform clouds. In the upper portions of these clouds,Expand
Investigating the contribution of secondary ice production to in‐cloud ice crystal numbers
In-cloud measurements of ice crystal number concentration can be orders of magnitude higher than the pre-cloud ice nucleating particle number concentration. This disparity may be explained withExpand

Secondary ice particle production during rime growth: The effect of drop size distribution and rimer velocity
The rate of production of secondary ice particles during the growth of rime in a supercooled cloud at about -5°C is known to depend mainly upon the rate of accretion of large drops (diameter ⩾25 mm).Expand
Criteria for the Onset of Significant Concentrations of Ice Particles in cumulus clouds
Abstract Field observations and measurements, reported from many locations around the world, are used to deduce the cloud depths (and cloud top temperatures) required for the Onset of SignificantExpand


Concentrations of Ice Crystals in Clouds
Abstract Some cumulus clouds appear to be capable of producing ice crystals in concentrations of 10–100l−1 at temperatures approaching −5C. This has serious implications for cloud seeding with iceExpand
Production of secondary ice particles during the riming process
ICE crystals play a vital part in the formation of precipitation, particularly outside the tropics, so it is important to know the concentrations of ice particles in natural clouds and to attempt toExpand
Ice crystal concentrations in cumulus and stratocumulus clouds
Concentrations of ice crystals of the order of 100 l−1 were found in some of the cumulus clouds sampled on four different days over or near the Australian mainland. These concentrations were 102 toExpand
The Glaciating Behavior of Small Cumulonimbus Clouds
Abstract Data gathered during consecutive traverses through summer clouds in southern Missouri have been interpreted to indicate that: (1) the glaciating characteristics of commonly occurring smallExpand
Ice particles in maritime clouds near Tasmania
An instrumented aircraft was used to sample particles in the upper regions of small supercooled cumulus clouds in maritime air off the Tasmanian coast in May 1968. 114 clouds were studied on nineExpand
What is the Role of Ice in Summer Rain-Showers?.
Abstract Recent observations indicate that ice pellets and snow pellets are present in most convective clouds in the Central United States by the time these clouds reach top temperatures of −10C. TheExpand
The Cascade Impactor: An Instrument for Sampling Coarse Aerosols
A new instrument is described which will sample windborne and stationary aerosols such as natural fogs and clouds, fine sprays, insecticidal mists, coarse dusts, pollen and spores, etc. By means ofExpand
