- Fractal dimension does not vary between instruments within a dense detector array.
- Interstorm variability of fractal dimension can be substantial.
- Fractal dimension consistently decreases monotonically with increasing drop size.
- Fractal dimension is not well correlated to bulk rainfall variables.
SummaryA dense network of optical disdrometers with 1Â min resolution was utilized through the winter months of 2013-2014 in South Carolina, USA, to explore the manner in which box-counting fractal dimension is related to drop size. Ten storms of a duration exceeding eight hours were selected for detailed analysis. It was discovered that detector-to-detector variation within each storm was negligible, though storm-to-storm variability could be substantial. The box-counting fractal dimension was found to decrease with increasing drop size, suggesting that large drops are more temporally clustered than small drops. Implications for raindrop sampling are discussed.
