Entrainment and the droplet spectrum in cumulus clouds

Quarterly Journal of the Royal Meteorological Society, 1982
AbstractThe model of the development of the droplet spectrum in cumulus clouds described by Mason and Jonas (1974) has been used to calculate the spectrum in penetrating downdraughts and the changes which occur when a region of dry air resulting from such a downdraught is subsequently forced to rise. It is shown that evaporation in the downdraught does

The effect of fluorescent tracers on droplet spectrum, viscosity, and density of pesticide formulations

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 2010
The most important factor affecting efficacy and drift of pesticide applications is the droplet spectrum. To measure pesticide drift, researchers utilize fluorescent tracers to rapidly quantify spray deposition. Although fluorescent tracers have been used for more than 50 years, no experiments have been performed on the effect they have on the ...

Droplet Spectrum Analysis from Artificially Generated Rain Showers

open access: yesJournal of Irrigation and Drainage Engineering, 2014
AbstractSevere droughts were experienced by many southerly states of the Indian subcontinent during the past decade. Farmer suicides were reported from the state of Andhra Pradesh year after year, especially when the monsoons failed. The government of India conducted expensive rain enhancement experiments through artificial cloud seeding; this did ...

Sampling Techniques to Determine Droplet Size Spectrum for Fan Nozzles

1990
Droplet size measurements obtained by sampling at discrete spray plume locations were compared to those obtained by sweeping the spray plume from fan nozzles through the sampling area of a laser droplet imaging probe. A mixture of water, 2.5% Tenneco 500/100 solvent and 0.5% Titron X-100 adjuvant was sprayed through flat spray and even flat spray ...

Polydispersed droplet spectrum and exergy analysis in wet steam flows using method of moments

open access: yesApplied Thermal Engineering, 2021
In steam turbine flow, the complex droplet spectrum caused by nonequilibrium condensation is necessary to be modeled accurately to predict the droplet behavior and estimate the exergy destruction and erosion rate.

The Microstructure of Cumulus Cloud. Part I. General Features of the Droplet Spectrum

Journals of the Atmospheric Sciences, 1969
Abstract From the examination of a large number of droplet samples in cumulus clouds it is found that many droplet-size distributions have neither positive skewness nor a single mode. Bimodal distributions increase in frequency with height above cloud base and with decreasing stability in the cloud environment, and it is suggested that they are ...

Infrared Spectrum of Fulvenallene and Fulvenallenyl in Helium Droplets

The Journal of Physical Chemistry A, 2019
Fulvenallene is the global minimum on the C7H6 potential energy surface. Rearrangement of fulvenallene to other C7H6 species and dissociation to produce fulvenallenyl radical (C7H5) is carried out in a continuous-wave SiC pyrolysis furnace at 1500 K. Prompt pick-up and solvation by helium droplets allows for the acquisition of vibrational spectra of ...
