. Plan views of accumulated precipitation within the model’s innermost domains and the stage IV product at two different times. Data are from the models’ Low-CCN simulations (see section 2b ), which had generally more precipitation than the High-CCN simulations. (a)–(h) Accumulated precipitation from 1600 to 1900 UTC 19 Jun 2013. (i)–(p) Accumulated precipitation from 1600 UTC 19 Jun to 0400 UTC 20 Jun 2013. The black square represents the location of the KHGX radar. Note that the model horizontal

mounted and immediately imaged using an inverted fluorescence microscope (wide-field Nikon TE2000-U) with a Plan Apochromat (VC 100x), 1.4 numerical aperture oil immersion objective (Nikon Instruments, Japan) and a CoolSNAP HQ charge-coupled device camera (Photometrics Inc.). Bacteria and viruses were counted in at least 20–30 fields of view at 490/528 nm (excitation/emission). Seawater, SML, and SSA collections were made every other day [note: aerosol measurements of heterotrophic bacteria (HB) began

panel overlay each other. Finally, double-moment bulk microphysics schemes still rely on considerable simplifications for the formation, growth, and fallout of ice particles. We plan to expand simulations discussed here through the application of the bin microphysics, as in Fan et al. (2013) . We will report the results of such simulations in the next installment of this series.

threshold for how increasing or decreasing urban aerosols can influence regional precipitation. These changes in the precipitation patterns and locations of severe weather could impact urban planning and agriculture, as this study suggests that severe weather can be sensitive to the magnitude of urban emissions. The use of realistic, evolving aerosol concentrations within these simulations shows the effects that the concentrations have on different stages of the storm and indicates the nonlinearity of

mechanism. The water confined in pores and cavities is assumed to freeze homogeneously in the case of soot, whereas the water confined in desert dust pores seems to freeze heterogeneously. For both ice nucleation modes, more experiments are needed to fill gaps in the datasets and to provide a more robust base for accurate parameterizations, in particular at high ice supersaturations and low temperatures of the cold cirrus regime. We also plan to evaluate AIDA experiments with other atmospherically
