They act as cloud condensation and ice nuclei and may have an influence on the hydrological cycle. Here we investigate a...

[1] The cloud‐air transition zone at stratiform cloud edges is an electrically active region where droplet charging has been predicted. Cloud edge droplet charging is expected from vertical flow of cosmic ray generated atmospheric ions in the globa l e lec t r i c c i rcu i t . Exper imenta l confirmation of stratiform cloud edge electrification is presented here, through charge and droplet mea...

Two Multi-Layer Perceptron (MLP) models are developed to estimate the radar reflectivity factor (dBZ) and rain intensity (R) from the spectral moments of an L-band wind profiler. Out of the four spectral moment inputs of the MLP models, the backscattered power (P) and Doppler velocity (VD) were found to have better correlation with the rain parameters. The model results were validated with the ...

In this study, a new set of reflectivity equations is introduced into the ARPS (Advanced Regional Prediction System) cloud analysis system. This set of equations incorporates double moment microphysics information in the analysis by adopting a set of diagnostic relationships between the intercept parameters and the corresponding mass mixing ratios. A reflectivityand temperature-based graupel cl...

Two-dimensional video disdrometer (2DVD) data were analyzed from two equatorial Indian (Gan) and west Pacific Ocean (Manus) islands where precipitation is primarily organized by the intertropical convergence zone and theMadden–Julian oscillation (MJO). The 18 (3.5) months of 2DVDdata fromManus (Gan) Island show that 1) the two sites have similar drop size distribution (DSD) spectra of liquid wa...

The WHIP (Workflows Hosted In Portals) project is building a set of software plug-ins to enable interactive, user driven, workflow integration, sharing, and collaboration within Web portals. This software architecture enables the dynamic publishing of workflows, facilitating information exchange and scientific collaboration. The WHIP plug-in provides functionality to perform composition, editin...

Observations from the International Winter Monsoon Experiment (Winter MONEX) have been used to determine temperature changes in the lower troposphere beneath the stratiform components of tropical mesoscale convective systems. It is found that while the apparent heat source Q1 in the lower troposphere beneath the stratiform cloud systems is negative (due to hydrometeor melting and evaporation), ...
