AbstractHail and graupel are linked to lightning production and are important components of cloud evolution. Hail can also cause significant damage when it precipitates to the surface. The accurate prediction of the amount and location of hail and graupel and the effects on the other hydrometeor species depends upon the size distribution assumed. Here, we use ~310 km of in situ observations from flights of the South Dakota School of Mines and Technology T-28 storm-penetrating aircraft to constrain the representation of the particle size distribution (PSD) of hail. The maximum ~1-km hail water content encountered was 9 g m−3. Optical probe PSD measurements are normalized using two-moment normalization relations to obtain an underlying exponential shape. By linking the two normalizing moments through a power law, a parameterization of the hail PSD is provided based on the hail water content only. Preliminary numerical weather simulations indicate that the new parameterization produces increased radar reflectivity relative to commonly used PSD representations.

The feasibility of sapphire fiber sensors based on evanescent absorption spectroscopy in the infrared range for determination of water content in polar organic solvents has been investigated. Evanescent absorption spectra of sapphire fiber sensors in glycerol, ethanol and glycol with different volume concentrations were recorded and analyzed, respectively. Evanescent absorbance around 2.7μm of fiber sensors in those organic solvents has been utilized to implement for in situ monitoring water concentration in organic solvents. The evanescent fiber sensors for monitoring water concentrations in those organic solvents are acceptably accurate, cost-effective and reliable. Overall results demonstrate that the sapphire fiber sensor based on evanescent absorption is a promising candidate for prediction of water content in polar organic solvents in on-line and remote situation.
