On the Variability of Drop Size Distributions over Areas
Publisher: American Meteorological Society
Abstract: ast studies of the variability of drop size distributions (DSDs) have used moments of the distribution such as the mass-weighted mean drop size as proxies for the entire size distribution. In this study, however, the authors ...
Disdrometer Network Observations of Finescale Spatial–Temporal Clustering in Rain
Publisher: American Meteorological Society
Abstract: he spatial clustering of drops is a defining characteristic of rain on all scales from centimeters to kilometers. It is the physical basis for much of the observed variability in rain. The authors report here on the ...
An Example of Persistent Microstructure in a Long Rain Event
Publisher: American Meteorological Society
Abstract: 2D video disdrometer (2DVD) probe was used to gather detailed drop measurements over a 770-min rain event. Accumulated totals of the rainfall and of the number of drops for each square centimeter showed persistent, significant ...
On the Detection of Statistical Heterogeneity in Rain Measurements
Publisher: American Meteorological Society
Abstract: AbstractThe application of the Wiener?Khintchine theorem for translating a readily measured correlation function into the variance spectrum, important for scale analyses and for scaling transformations of data, requires ...
Small-Scale Drop Size Variability: Impact on Estimation of Cloud Optical Properties
Publisher: American Meteorological Society
Abstract: Most cloud radiation models and conventional data processing techniques assume that the mean number of drops of a given radius is proportional to volume. The analysis of microphysical data on liquid water drop sizes shows ...
